谁有android4.2的机子帮试段代码
没有4.2的机子,帮帮忙,谢谢看看视频是否全屏的
代码如下

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getViews();
ViewTreeObserver vto = videoView1.getViewTreeObserver();
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
public boolean onPreDraw() {
int height = videoView1.getMeasuredHeight();
int width = videoView1.getMeasuredWidth();
Toast.makeText(MainActivity.this, "w = " + width + " h = " + height,
Toast.LENGTH_SHORT).show();
return true;
}
});
mediaController = new MediaController(this);
// String videoPath = "/sdcard/MSDgames/videos/v2_bak.mp4";

if (videoFile.exists() && videoFile.isFile()) {
videoView1.setVideoPath(videoFile.getAbsolutePath());
videoView1.setMediaController(mediaController);
mediaController.setMediaPlayer(videoView1);
videoView1.requestFocus();
videoView1.start();
// int w = View.MeasureSpec.makeMeasureSpec(0,
// View.MeasureSpec.UNSPECIFIED);
// int h = View.MeasureSpec.makeMeasureSpec(0,
// View.MeasureSpec.UNSPECIFIED);
// videoView1.measure(w, h);
// int height = videoView1.getMeasuredHeight();
// int width = videoView1.getMeasuredWidth();
//
// int height = videoView1.getHeight();
// int width = videoView1.getWidth();
// Toast.makeText(this, "w = " + width + " h = " + height,

} else {
Toast.makeText(this, "no video", Toast.LENGTH_SHORT).show();
}
}

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"--------------------编程问答-------------------- 忘了说了,需要修改视频地址
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<com.example.testvideoview.ui.MyVideoView

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" />
</RelativeLayout>
在android4.1中是可以全屏的 --------------------编程问答-------------------- 还有一个文件
<?xml version="1.0" encoding="utf-8"?>--------------------编程问答-------------------- 试了试,添加了视频但还是不能播放,图:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testvideoview"
android:versionCode="1"
android:versionName="1.0" >

--------------------编程问答-------------------- 非常感谢ls
请问视频路径改了吗? --------------------编程问答-------------------- AVD. --------------------编程问答-------------------- 搞笑的求助。。。搞笑的回答哈哈,模拟器而已啊,你更新4.2的sdk而后启动4.2的模拟器不就可以自己测了嘛...... --------------------编程问答-------------------- 不过关注楼主的学习进程~~~~
