在播放优酷视频, 点击全屏的时候, 会黑屏, 而不显示需要全屏的view

试过各种方法, 发现有一些细节需要注意:

1. demo的Manifest Activity需要设置为: 全屏, 横屏

android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen"

android:screenOrientation="landscape" />注意: 此处如果不设置为 横屏 点击全屏也会失败的

有的说播放flash是需要在Activity添加硬件加速的属性, 这个demo是在程序判断, 所以没有添加

2. 添加权限:

3. 退出视频播放会出现视频还没停止的问题:

@Override

public void onPause() {// 继承自Activity

super.onPause();

mWebView.onPause();

}

@Override

public void onResume() {// 继承自Activity

super.onResume();

mWebView.onResume();

}

@Override

public boolean onKeyDown(int keyCode, KeyEvent event) {

if (keyCode == KeyEvent.KEYCODE_BACK

&& event.getAction() == KeyEvent.ACTION_DOWN) {

mWebView.loadData("", "text/html; charset=UTF-8", null);

finish();

return true;

}

return super.onKeyDown(keyCode, event);

}

当按下返回时, 设置Webview加载空

代码:

xml文件: act_flashplay.xml

android:layout_width="match_parent"

android:layout_height="match_parent">

android:id="@+id/fullscreen_custom_content"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:visibility="gone" />

android:id="@+id/main_content"

android:layout_width="match_parent"

android:layout_height="match_parent">

android:id="@+id/webview_player"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:scrollbars="none" />

注: demo中的方法是loadUrl, load的是asset文件夹下的1234.html, 可以播放视频, 同样的,上面代码中用loadData也是可以的

大家可以试一试, 有什么问题可以一起讨论
