Android视频播放器ExoPlayer全屏
布局添加全屏按键
1. app gradle
dependencies {
implementation 'com.google.android.exoplayer:exoplayer:2.11.1'android {
compileOptions { targetCompatibility JavaVersion.VERSION_1_8 }2. AndroidManifest配置权限
权限
-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 屏幕允许翻转
:name=".MainActivity" android:configChanges="orientation">3. activity布局
注意：使用自定义布局，需要在exoplayer2.ui.PlayerView中，使用app:controller_layout_id指明使用的布局文件
MainActivity

全屏
requestWindowFeature(Window.FEATURE_NO_TITLE); // 隐藏标题 //这行代码一定要在setContentView之前，不然会闪退int flagsFullScreen = WindowManager.LayoutParams.FLAG_FULLSCREEN;getWindow().addFlags(flagsFullScreen); // 设置全屏//如果上面的不起作用，可以换成下面的。if (getSupportActionBar()!=null) getSupportActionBar().hide(); //应用标题栏退出全屏
WindowManager.LayoutParams attrs = getWindow().getAttributes();attrs.flags &= (~flagsFullScreen);getWindow().setAttributes(attrs);getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);if (getSupportActionBar()!=null) getSupportActionBar().show(); //应用标题栏初始化播放器
private void initializePlayer() { player = new SimpleExoPlayer.Builder(context).build(); playerView.setPlayer(player); DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, Util.getUserAgent(context,"myExoPlayer")); MediaSource mediaSource = new ProgressiveMediaSource.Factory(dataSourceFactory) .createMediaSource(Uri.parse(Environment.getExternalStorageDirectory() + "/1.mp4")); player.prepare(mediaSource); }参考链接:
