使用步骤
1. 在project的build.gradle添加如下代码(如下图)
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
2. 在Module的build.gradle添加依赖
compile 'com.github.open-android:ExoPlayer:1.0'
3. 复制如下代码到xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:background="#fff"
>
<RelativeLayout
android:id="@+id/video_skin"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000">
<com.google.android.exoplayer.AspectRatioFrameLayout
android:id="@+id/video_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
>
<SurfaceView
android:id="@+id/surface_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
/>
</com.google.android.exoplayer.AspectRatioFrameLayout>
<RelativeLayout
android:id="@+id/video_control"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#000"
>
<ImageButton
android:id="@+id/py"
android:layout_width="30dp"
android:layout_height="30dp"
android:padding="5dp"
android:background="@drawable/pause"/>
<SeekBar
android:id="@+id/sk"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toRightOf="@+id/py"
android:layout_toLeftOf="@+id/fs"/>
<ImageButton
android:id="@+id/fs"
android:layout_width="30dp"
android:layout_height="30dp"
android:padding="5dp"
android:layout_alignParentRight="true"
android:background="@drawable/full"/>
</RelativeLayout>
</RelativeLayout>
</RelativeLayout>
4. 复制如下代码到Activity
public class MainActivity extends Activity implements SurfaceHolder.Callback, DemoPlayer

5.添加权限
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
细节注意:
contentUri:表示视频的uri
