我有一台SurfaceView媒体播放器。我试图找到一个在全屏和嵌入模式之间切换的解决方案。自定义媒体控制器是使用这篇热门文章http://www.brightec.co.uk/ideas/custom-android-media-controller为MediaPlayer开发的。所以现在我在自定义媒体控制器上有按钮来切换模式。
活动的XML(未完整)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<ListView
android:id="@+id/lvMain"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:background="#20FFFFFF" >
</ListView>
<FrameLayout
android:id="@+id/videoSurfaceContainer"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<SurfaceView
android:id="@+id/videoSurface"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</FrameLayout>
</LinearLayout>
我找到了一个改变SurfaceView大小的解决方案,大小已经改变,但没有全屏显示,图片在他们的框架中:
@Override
public void toggleFullScreen() {
setFullScreen(isFullScreen());
}
@Override
public boolean isFullScreen() {
if(mFullScreen){
return false;
}else{
return true;
}
}
public void setFullScreen(boolean fullScreen){
fullScreen = false;
if (mFullScreen) {
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();
params.width = displaymetrics.widthPixels;
params.height = displaymetrics.heightPixels;
params.setMargins(0, 0, 0, 0);
mFullScreen = fullScreen;
}
else{
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
final FrameLayout mFrame = (FrameLayout) videoSurfaceContainer;
int height = mFrame.getHeight();
int width = mFrame.getWidth();
android.widget.FrameLayout.LayoutParams params = (android.widget.FrameLayout.LayoutParams) videoSurface.getLayoutParams();
params.width = width;
params.height= height;
params.setMargins(0, 0, 0, 0);
mFullScreen = !fullScreen;
}
}

目前还不清楚你在寻找什么,所以我只是提出一些想法:
- 我认为SurfaceView无法动态调整大小。您必须使视图无效/重新创建。 TextureView提供更好的视图处理效果,但性能很小。
- 如果您只想切换到全屏活动(没有actinobars等):请参阅here for android&gt; 4.4否则你需要在onCreate上执行它(因此需要活动刷新才能生效):
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(YOURFULLSCREENCHECKHERE) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
setContentView(R.layout.main);
}

我决定让所有其他ViewGroups和ListView不可见,在这种情况下,SurfaceView就像在全屏模式下一样
if (mFullScreen) {
paneltop.setVisibility(View.GONE);
panelbottom.setVisibility(View.GONE);
lvMain.setVisibility(View.GONE);
mFullScreen = fullScreen;
}
else{
paneltop.setVisibility(View.VISIBLE);
panelbottom.setVisibility(View.VISIBLE);
lvMain.setVisibility(View.VISIBLE);
mFullScreen = !fullScreen;
}
