无法向搜索者添加搜索栏
我指的是 https://medium.com/google-exoplayer/customizing-exoplayers-ui-components-728cf55ee07a
将自定义播放暂停按钮和搜索栏添加到exoplayer
这是我正在尝试的代码
public class ExoplayerAct extends Activity implements VideoRendererEventListener {
private static final String TAG = "MainActivity";
private SimpleExoPlayerView simpleExoPlayerView;
private SimpleExoPlayer player;
private TextView resolutionTextView;
String j;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.exoplayer);
resolutionTextView = new TextView(this);
resolutionTextView = (TextView) findViewById(R.id.resolution_textView);
Intent iin = getIntent();
Bundle b = iin.getExtras();
if (b != null) {
j = (String) b.get("fileVideoPath");
}
// 1. Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
// 2. Create a default LoadControl
LoadControl loadControl = new DefaultLoadControl();
// 3. Create the player
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);
simpleExoPlayerView = new SimpleExoPlayerView(this);
simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);
//Set media controller
simpleExoPlayerView.setUseController(true);
simpleExoPlayerView.requestFocus();
// Bind the player to the view.
simpleExoPlayerView.setPlayer(player);
// I. ADJUST HERE:
//CHOOSE CONTENT: LiveStream / SdCard
//LIVE STREAM SOURCE: * Livestream links may be out of date so find any m3u8 files online and replace:
// Uri mp4VideoUri =Uri.parse("http://81.7.13.162/hls/ss1/index.m3u8"); //random 720p source
// Uri mp4VideoUri =Uri.parse("http://54.255.155.24:1935//Live/_definst_/amlst:sweetbcha1novD235L240P/playlist.m3u8"); //Radnom 540p indian channel
// Uri mp4VideoUri =Uri.parse("FIND A WORKING LINK ABD PLUg INTO HERE"); //PLUG INTO HERE<------------------------------------------
//VIDEO FROM SD CARD: (2 steps. set up file and path, then change videoSource to get the file)
// String urimp4 = "path/FileName.mp4"; //upload file to device and add path/name.mp4

//This is the MediaSource representing the media to be played:

//FOR LIVESTREAM LINK:
// MediaSource videoSource = new HlsMediaSource(mp4VideoUri, dataSourceFactory, 1, null, null);
final LoopingMediaSource loopingSource = new LoopingMediaSource(videoSource);
// Prepare the player with the source.
player.prepare(loopingSource);

exoplayer布局是
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:paddingLeft="@dimen/fab_margin"

android:paddingTop="@dimen/fab_margin"

如果我如上所述评论搜索栏，它可以正常工作
但如果我添加了搜索栏，则会给我错误
Caused by: java.lang.ClassCastException: android.widget.SeekBar cannot be cast to com.google.android.exoplayer2.ui.TimeBar
答案 0 :(得分：8)
在您的exo_playback_control_view布局中，将Seekbar替换为com.google.android.exoplayer2.ui.DefaultTimeBar
这是错误消息告诉您的内容，如果您检查文档here，您会发现为exo_progress控件指定的类型确实是TimeBar。
<com.google.android.exoplayer2.ui.DefaultTimeBar
android:id="@id/exo_progress"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="26dp"/>
