Closes the old #7474, keeping the status bar hidden when displaying a modal
or dialog, this is accomplished by verifying if the activity status bar is hidden or not.

Added a test to [RNTester](https://github.com/facebook/react-native/tree/master/RNTester), so it can be tested from there:

1. Run [RNTester](https://github.com/facebook/react-native/tree/master/RNTester) project
2. Go to <StatusBar> tests
3. Set `hidden: true` in the *StatusBar hidden* samples
4. Set `modal visible: true` and see the result

Here are some gifs to help see the results:

Janic Duplessis db061ea8c7 Don't wrap ListEmptyComponent in an extra view
Summary:
A common UI pattern for list empty states is some text/images centered inside the visible part of the list. This is pretty hard to do currently because we wrap ListEmptyComponent with an extra view with no way to style it so we cannot just use `flex: 1` to make it fill the available space.

- Added an example of ListEmptyComponent in the FlatList example in RNTester

Before (no way to make ListEmptyComponent fill the space):

Moti Zilberman 0459e4ffaa Support Image resizeMode=repeat on Android
Summary:
`<Image resizeMode="repeat" />` for Android, matching the iOS implementation (#7968). (Non-goal: changing the component's API for finer-grained control / feature parity with CSS - this would be nice in the future)

As requested in e.g. #14158.

Given https://github.com/facebook/fresco/issues/1575, and lacking the context to follow the specific recommendations in https://github.com/facebook/fresco/issues/1575#issuecomment-267004303, I've opted for a minimal change within RN itself.

It's likely that performance can be improved by offloading this work to Fresco in some clever way; but I'm assuming that the present naive approach is still an improvement over a userland implementation with `onLayout` and multiple `<Image>` instances.

- Picking up on a TODO note in the existing code, I implemented `MultiPostprocessor` to allow arbitrary chaining of Fresco-compatible postprocessors inside `ReactImageView`.
- Rather than extensively refactor `ImageResizeMode`, `ReactImageManager` and `ReactImageView`, I mostly preserved the existing API that maps `resizeMode` values to [`ScaleType`](http://frescolib.org/javadoc/reference/com/facebook/drawee/drawable/ScalingUtils.ScaleType.html) instances, and simply added a second mapping, to [`TileMode`](https://developer.android.com/reference/android/graphics/Shader.TileMode.html).
- To match the iOS rendering exactly for oversized images, I found that scaling with a custom `ScaleType` was required - a kind of combination of `CENTER_INSIDE` and `FIT_START` which Fresco doesn't provide - so I implemented that as `ScaleTypeStartInside`. (This is, frankly, questionable as the default behaviour on iOS to begin with - but I am aiming for parity here)
- `resizeMode="repeat"` is therefore unpacked by the view manager to the effect of:
  ```js
     view.setScaleType(ScaleTypeStartInside.INSTANCE);
     view.setTileMode(Shader.TileMode.REPEAT);
   ```
  And the added postprocessing in the view (in case of a non-`CLAMP` tile mode) consists of waiting for layout, allocating a destination bitmap and painting the source bitmap with the requested tile mode and scale type.

Note that as in https://github.com/facebook/react-native/pull/17398#issue-285235247, I have neither updated nor tested the "Flat" UI implementation - everything compiles but I've taken [this comment](https://github.com/facebook/react-native/issues/12770#issuecomment-294052694) to mean there's no point in trying to wade through it on my own right now; I'm happy to tackle it if given some pointers.

Also, I'm happy to address any code style issues or other feedback; I'm new to this codebase and a very infrequent Android/Java coder.

Tested by enabling the relevant case in RNTester on Android.

Moti Zilberman 5898817fc1 Implement letterSpacing on Android >= 5.0
Summary:
`letterSpacing` is completely missing from RN Android at the moment.

I've reviewed the `letterSpacing` implementations in #13199, #13877 and #16801 (that all seem to have stalled) and managed to put together an improved one based on #13199, updated to merge cleanly post 6114f863c3, that resolves the [issues](https://github.com/facebook/react-native/pull/13199#issuecomment-354568863) I've identified with that code.

I believe this is the closest PR yet to a correct implementation of this feature, with a few caveats:

- As with the other PRs, this only works on Android >= 5.0 (silently falling back to no letter spacing on older versions). Is this acceptable for a RN feature, in general? Would a dev mode warning be desirable?
- The other PRs seem to have explored the space of potential solutions to the layout issue ([Android renders space _around_ glyphs](https://issuetracker.google.com/issues/37079859), iOS to the _right_ of each one) and come up empty, so I've opted to merely document the difference.
- I have neither updated nor tested the "Flat" UI implementation - everything compiles but I've taken [this comment](https://github.com/facebook/react-native/issues/12770#issuecomment-294052694) to mean there's no point in trying to wade through it on my own right now; I'm happy to tackle it if given some pointers.
- The implementation in `ReactEditText` is only there to handle the placeholder text, as `ReactBaseTextShadowNode` already affects the input control's contents correctly.
  - I'm not sure whether `<TextInput>` is meant to respect `allowFontScaling`; I've taken my cue here from `ReactTextInputManager.setFontSize()`, and used the same units (SP) to interpret the value in `ReactEditText.setLetterSpacingPt()`.
  - I'm not sure whether `<TextInput>` is even meant to support `letterSpacing` - it doesn't actually work on iOS. I'm not going to be able to handle the Objective-C side of this, not as part of this PR at least.
- I have not added unit tests to `ReactTextTest` - is this desirable? I see that some other props such as `lineHeight` aren't covered there (unless I'm not looking in the right place).
- Overall, I'm new to this codebase, so it's likely I've missed something not mentioned here.

Krzysztof Magiera b48f7e5605 Support for animated tracking in native driver
Summary:
This PR adds support for Animated tracking to Animated Native Driver implementation on Android and iOS.

Animated tracking allows for animation to be started with a "dynamic" end value. Instead of passing a fixed number as end value we can pass a reference to another Animated.Value. Then when that value changes, the animation will be reconfigured to drive the animation to the new destination point. What is important is that animation will keep its state in the process of updating "toValue". That is if it is a spring animation and the end value changes while the previous animation still hasn't settled the new animation will start from the current position and will inherit current velocity. This makes end value transitions very smooth.

Animated tracking is available in JS implementation of Animated library but not in the native implementation. Therefore until now, it wasn't possible to utilize native driver when using animated tracking. Offloading animation from JS thread turns out to be crucial for gesture driven animations. This PR is a step forward towards feature parity between JS and native implementations of Animated.

Here is a link to example video that shows how tracking can be used to implement chat heads effect: https://twitter.com/kzzzf/status/958362032650244101

In addition this PR fixes an issue with frames animation driver on Android that because of rounding issues was taking one extra frame to start. Because of that change I had to update a number of Android unit tests that were relying on that behavior and running that one additional animation step prior to performing checks.

As a part of this PR I'm adding three unit tests for each of the platforms that verifies most important aspects of this implementation. Please refer to the code and look at the test cases top level comments to learn what they do.

I'm also adding a section to "Native Animated Example" screen in RNTester app that provides a test case for tracking. In the example we have blue square that fallows the red line drawn on screen. Line uses Animated.Value for it's position while square is connected via tracking spring animation to that value. So it is ought to follow the line. When user taps in the area surrounding the button new position for the red line is selected at random and the value updates. Then we can watch blue screen animate to that position.

You can also refer to this video that I use to demonstrate how tracking can be linked with native gesture events using react-native-gesture-handler lib: https://twitter.com/kzzzf/status/958362032650244101

[GENERAL][FEATURE][Native Animated] - Added support for animated tracking to native driver. Now you can use `useNativeDriver` flag with animations that track other Animated.Values

Adam Putinski 31288161e1 Add accessibilityElementsHidden prop
Summary:
Allow iOS to have similar accessibility functionality to Android. This PR exposes the `accessibilityElementsHidden` property on iOS which is similar to Android's `importantForAccessibility="no-hide-descendants"`

I didn't see any existing examples for testing native props being passed through, but I did add an example to the RNTester app. I've attached some screenshots using the Accessibility Inspector to verify the property was correctly passed through.

Valentin Shergin 2716f53220 The New <Text> on iOS
Summary:
This is a complete rewrite of RCTText, the part of React Native which manages Text and TextInput components.

Key points:

* It's understandable now. It follows a simple architectural pattern, and it's easy to debug and iterate. Text flow layout is a first-class citizen in React Native layout system now, not just a wired special case. It also brings entirely new possibilities such as nested interleaving <Text> and <View> components.
* All <Text>-specific APIs were removed from UIManager and co (it's about ~16 public methods which were used exclusively only by <Text>).
* It relies on new Yoga measurement/cloning API and on-dirty handler. So, it removes built-in dirty propagation subsystem from RN completely.
* It caches string fragments properly and granularly on a per-node basis which makes updating text-containing components more performant.
* It does not instantiate UIView for virtual components which reduces memory utilization.
* It drastically improves <TextInput> capabilities (e.g. rich text inside single line <TextInput> is now supported).

Spencer Ahrens 65184ec6b0 rename and extend new maintain visible content position feature
Summary:
Builds off of cae7179c94

- Make the prop a dictionary for more configuration options
- Rename `maintainPositionAtOrBeyondIndex` -> `maintainVisibleContentPosition` + `minIndexForVisible`
- Add autoscroll threshold feature

Given the async native of RN JS and background layout, there is no way to trigger the scrollTo from JS without risking a delay, so we add the feature in native code.

Spencer Ahrens cae7179c94 new feature to support smooth bi-directional content loading
Summary:
== Problem / Background ==

Most lists paginate in a single direction (standard infinite list), but some paginate in both directions. Most common example is a chat thread where new messages show up on the bottom, and old content can be loaded by scrolling up. Comment threads are another example.

Right now, adding content to the bottom of a scroll view is smooth - the content doesn't jump. But when adding to the top of the scrollview, the content gets pushed down, which is jarring (note this may appear reversed because of inverting the list which is common for chat applications).

== Approach ==

The basic idea is simple - we set a flag in JS, then for every uimanager transaction, we record which is the first eligible and visible view in the ScrollView, and compare it's new origin to the old one. If it has changed, we update the contentOffset of the ScrollView to compensate.

This is done by observing `willPerformMounting` directly (only from scrollviews that have this new property set), and then observing the prev state with prependUIBlock and making the update synchronously in addUIBlock to avoid any flicker.

There is also a way to skip views that we don't care about, like a spinner at the top of the view that we don't want to stay in place - we actually want it to get pushed up by the new content, replaced visually in the viewport.

== Notes ==

Most chat applications will probably want to do a scrollToTop when new content comes in and the user is already scrolled at or near the bottom.

This is glitchy if visible children are re-ordered, which could be fixed with additional logic, but it doesn't come up in the type of applications we're targetting here so punting on that.

== Test Plan ==

Josh Hargreaves c9ff0bc212 Implement onKeyPress Android
Summary:
This implements onKeyPress for Android on TextInputs and addresses https://github.com/facebook/react-native/issues/1882.
**N.B. that this PR has not yet addressed hardware keyboard inputs**, but doing will be fairly trivial. The main challenge was doing this for soft keyboard inputs.

I've tried to match the style as much as I could. Will happily make any suggested edits be they architectural or stylistic design (edit: and of course implementation), but hopefully this is a good first pass :).
I think important to test this on the most popular keyboard types; maybe different languages too.
I have not yet added tests to test implementation, but will be happy to do that also.

- Build & run RNTester project for Android and open TextInput.
- Enter keys into 'event handling' TextInput.
- Verify that keys you enter appear in onKeyPress below the text input
- Test with autocorrect off, on same input and validate that results are the same.

Below is a gif of PR in action.

Douglas 45185947ee Fix tvOS compile issues; enable TVEventHandler in Modal (fix #15389)
Summary:
**Motivation**

Fix an issue (#15389) where `TVEventHandler` would not work when a modal was visible.  The solution adds the gesture recognizers from the native `RCTTVRemoteHandler` to the native modal view (except for the menu button recognizer, which still needs special handling in modals).  This PR also fixes some breakages in compiling React Native for tvOS.

**Test plan**

Compilation fixes should enable tvOS compile test to pass in Travis CI.

The modal fix can be tested with the following component, modified from the original source in #15389 .

``` javascript
import React, { Component } from 'react';
import ReactNative from 'ReactNative';
import {
    Text,
    View,
    StyleSheet,
    TouchableHighlight,
    TVEventHandler,
    Modal,
} from 'react-native';

export default class Events extends Component {

    constructor(props) {
        super(props);

        this.state = {
            modalVisible: false,
        };
        this._tvEventHandler = new TVEventHandler();
    }

    _enableTVEventHandler() {
        this._tvEventHandler.enable(this, (cmp, evt) => {
            const myTag = ReactNative.findNodeHandle(cmp);
            console.log('Event.js TVEventHandler: ', evt.eventType);
            // if (evt.eventType !== 'blur' && evt.eventType !== 'focus') {
            //  console.log('Event.js TVEventHandler: ', evt.eventType);
            // }
        });
    }

    _disableTVEventHandler() {
        if (this._tvEventHandler) {
            this._tvEventHandler.disable();
            delete this._tvEventHandler;
        }
    }

    componentDidMount() {
        this._enableTVEventHandler();
    }

Valentin Shergin 7bd0855650 Native implementation of <Image> intrinsic content size on iOS
Summary:
Now intrinsic content size of <Image> is implemented natively on iOS and now it is actually
`intrinsicContentSize`, not just overrided `height` and `width` styles (which was incorrect and hacky).
This change also removes support of nested content inside <Image>.
This is a first commit in the row where we improve <Image> implementation.

Daniel Friesen 28824f8eb3 Implement a JSTester example for the Dimensions API
Summary:
JSTester is missing a page for the Dimensions API. This also makes it hard to test out some things in the tester app that affect the app's frame when you need to know how they affect the dimensions.
