主要是继承自Presentation，实现是借鉴另一位大牛的代码，
上代码，最后回帖上源码MediaPresentation 里面主要是实现客显示的布局，一个是视频的布局，一个是图片的布局，具体实现源码可以看到，只贴例子：这个是视频的客显布局
public class MediaPresentation extends Presentation {
private SurfaceView presentSurface;
public MediaPresentation(Context outerContext, Display display,boolean vedioorimageflag) {
super(outerContext, display);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.presentation_layout);
presentSurface = (SurfaceView) findViewById(R.id.present_surface);
}
public SurfaceView getSurface() {
return presentSurface;
}
}图片的客显。就不贴代码了
主activity 里面的代码，主要是发送广播和开启服务的代码；
public class MainActivity extends Activity {
private boolean isAirplay = false;
private final static String SERVICE_ACTION = "com.ryx.twovideos.actions";
private final static String Image_ACTION = "com.image.changeimage";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
Button change =(Button) findViewById(R.id.change);
change.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (!isAirplay) {
Intent imageBroadcast = new Intent(Image_ACTION);
sendBroadcast(imageBroadcast);
Intent i = new Intent(MainActivity.this, MediaService.class);
startService(i);
isAirplay = true;
} else {
Intent i = new Intent(SERVICE_ACTION);
sendBroadcast(i);
Intent image = new Intent(MainActivity.this, ImageService.class);
startService(image);
isAirplay = false;
}
}
});
Intent image = new Intent(MainActivity.this, ImageService.class);
startService(image);
}
}最后再贴一个开启的服务去对客显。做一些页面的填充及处理；
public class MediaService extends Service {
