广告机的例子（播放视频）

突然接到的需求，东平西凑的广告机，可以实现循环播放本地视频。

MainActivity

requestWindowFeature(Window.FEATURE_NO_TITLE);//隐藏标题
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);//设置全屏
setContentView(R.layout.activity_main);
videoView = (FullScreenVideoView) findViewById(R.id.video_view);
/**
* VideoView控制视频播放的功能相对较少，具体而言，它只有start和pause方法。为了提供更多的控制，
* 可以实例化一个MediaController，并通过setMediaController方法把它设置为VideoView的控制器。
*/
videoView.setMediaController(new MediaController(this));
videoUri = Uri.parse("/sdcard/" + "2.mp4");
videoView.setVideoURI(videoUri);
videoView.start();

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
mp.setLooping(true);

}
});
videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
videoView.setVideoURI(videoUri);
videoView.start();
}
});

网上抄的全屏的VideoView。

public class FullScreenVideoView extends VideoView {

private int videoWidth;
private int videoHeight;

public FullScreenVideoView(Context context) {
super(context);
}

public FullScreenVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public FullScreenVideoView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int width = getDefaultSize(videoWidth, widthMeasureSpec);
int height = getDefaultSize(videoHeight, heightMeasureSpec);
if (videoWidth > 0 && videoHeight > 0) {
if (videoWidth * height > width * videoHeight) {
height = width * videoHeight / videoWidth;
} else if (videoWidth * height < width * videoHeight) {
width = height * videoWidth / videoHeight;
}
}
setMeasuredDimension(width, height);
}

public int getVideoWidth() {
return videoWidth;
}

public void setVideoWidth(int videoWidth) {
this.videoWidth = videoWidth;
}

public int getVideoHeight() {
return videoHeight;
}

public void setVideoHeight(int videoHeight) {
this.videoHeight = videoHeight;
}

}
