android – 如何将搜索栏添加到Exoplayer exo_playback_control_view.xml

作者:互联网

不能向搜索者添加搜索栏

我指的是
https://medium.com/google-exoplayer/customizing-exoplayers-ui-components-728cf55ee07a

添加自定义播放暂停按钮和搜索栏到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//LIVE STREAM SOURCE: * Livestream links may be out of date so find any m3u8 files online and replace: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
//         Uri mp4VideoUri = Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath()+"/2010a.mp4");

        Uri mp4VideoUri = Uri.parse(j);





//Measures bandwidth during playback. Can be null if not required.
        DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();
//Produces DataSource instances through which media data is loaded.
        DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this
                , Util.getUserAgent(this, "exoplayer2example"), bandwidthMeterA);
//Produces Extractor instances for parsing the media data.
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();


// II. ADJUST HERE:

//This is the MediaSource representing the media to be played:
//FOR SD CARD SOURCE:
        MediaSource videoSource = new ExtractorMediaSource(mp4VideoUri, dataSourceFactory, extractorsFactory, null, null);

//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);

        player.addListener(new ExoPlayer.EventListener() {

            }

            @Override

            }

            @Override

            }
        });
        PlaybackParameters playbackParameters = new PlaybackParameters(2.0f, 1.0f);
        player.setPlaybackParameters(playbackParameters);

        player.setPlayWhenReady(true); //run file/link when ready to play.
        player.setVideoDebugListener(this); //for listening to resolution change and  outputing the resolution
    }//End of onCreate

    @Override

//-------------------------------------------------------ANDROID LIFECYCLE---------------------------------------------------------------------------------------------

    @Override
    protected void onStop() {
        super.onStop();
        Log.v(TAG, "onStop()...");
    }

    @Override
    protected void onStart() {
        super.onStart();
        Log.v(TAG, "onStart()...");
    }

    @Override

        super.onDestroy();
        Log.v(TAG, "onDestroy()...");
        player.release();
    }
}

exoplayer布局是

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/fab_margin"
    android:paddingLeft="@dimen/fab_margin"
    android:paddingRight="@dimen/fab_margin"
    android:paddingTop="@dimen/fab_margin"
    tools:context="com.ayalus.exoplayer2example.MainActivity">

    <TextView
        android:id="@+id/sample_app_title"
        android:text="ExoPlayer 2 Example App:"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="40sp"
        android:textColor="#000000"
        android:gravity="center_horizontal"/>

    <TextView
        android:id="@+id/resolution_textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Resolution"
        android:textSize="40px"
        android:background="#FFFFFF"
        android:textColor="#000000"
        android:layout_below="@+id/sample_app_title"
        android:gravity="center_horizontal"/>

    <com.google.android.exoplayer2.ui.SimpleExoPlayerView
        android:id="@+id/player_view"
        android:focusable="true"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/resolution_textView"
        app:use_controller="false"
        android:layout_marginTop="10dp" />




</RelativeLayout>

和自定义exo_playback_control_view

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"

    android:background="#CC000000"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:paddingTop="4dp"
        android:orientation="horizontal">

        <ImageButton android:id="@id/exo_prev"
            android:visibility="gone"
            style="@style/ExoMediaButton.Previous"/>

        <ImageButton android:id="@id/exo_rew"
            android:visibility="gone"
            style="@style/ExoMediaButton.Rewind"/>

        <ImageButton android:id="@id/exo_play"
            style="@style/ExoMediaButton.Play"/>

        <ImageButton android:id="@id/exo_pause"
            style="@style/ExoMediaButton.Pause"/>

        <ImageButton android:id="@id/exo_ffwd"
            android:visibility="gone"
            style="@style/ExoMediaButton.FastForward"/>

        <ImageButton android:id="@id/exo_next"
            android:visibility="gone"
            style="@style/ExoMediaButton.Next"/>

    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="4dp"
        android:gravity="center_vertical"
        android:orientation="horizontal">

        <TextView android:id="@id/exo_position"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="14sp"
            android:textStyle="bold"
            android:paddingLeft="4dp"
            android:paddingRight="4dp"
            android:includeFontPadding="false"
            android:textColor="#FFBEBEBE"/>

        <!--<SeekBar android:id="@id/exo_progress"-->
            <!--android:layout_width="0dp"-->
            <!--android:layout_weight="1"-->
            <!--android:layout_height="32dp"-->
            <!--android:focusable="false"-->
            <!--style="?android:attr/progressBarStyleHorizontal"/>-->

        <TextView android:id="@id/exo_duration"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="14sp"
            android:textStyle="bold"
            android:paddingLeft="4dp"
            android:paddingRight="4dp"
            android:includeFontPadding="false"
            android:textColor="#FFBEBEBE"/>

    </LinearLayout>

</LinearLayout>

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,它会给我错误

Caused by: java.lang.ClassCastException: android.widget.SeekBar cannot be cast to com.google.android.exoplayer2.ui.TimeBar

解决方法:

在exo_playback_control_view布局中,用com.google.android.exoplayer2.ui.DefaultTimeBar替换Seekbar

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"/>
