二、使用

1. 添加依賴

implementation 'com.google.android.exoplayer:exoplayer:2.11.0'      

2. 清單檔案中申請權限及 application 設定

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.hk.test">

    <uses-permission android:name="android.permission.INTERNET"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/app_icon"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:usesCleartextTraffic="true"     //需加上，避免報錯
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>      

3. 布局檔案

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.google.android.exoplayer2.ui.PlayerView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>      

4. MainActivity.java

public class MainActivity extends AppCompatActivity {
    private PlayerView mPlayerView;

    private SimpleExoPlayer player;

    private boolean playWhenReady;

    private int currentWindow;

    private long playbackPosition;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        init();
    }

    private void init() {
       mPlayerView = findViewById(R.id.video_view);
       initializePlayer();
    }

    private void initializePlayer() {
        player = new SimpleExoPlayer.Builder(this).build();

        player.setPlayWhenReady(playWhenReady);
        player.seekTo(currentWindow, playbackPosition);
        Uri playUri = Uri.parse("https://stream7.iqilu.com/10339/upload_transcode/202002/18/20200218114723HDu3hhxqIT.mp4");
        MediaSource mediaSource = buildMediaSource(playUri);
        player.prepare(mediaSource, true, false);

        mPlayerView.setPlayer(player);
    }

    private MediaSource buildMediaSource(Uri uri) {
        DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this, "com.example.exoplayerdemo");
        MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(uri);
        return videoSource;
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        player.release();
    }
}
