Android学习——使用videoView 来播放视频

定义一个videoview 组件

<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android”

    xmlns:tools=”http://schemas.android.com/tools” android:layout_width=”match_parent”

    android:layout_height=”match_parent” android:paddingLeft=”@dimen/activity_horizontal_margin”

    android:paddingRight=”@dimen/activity_horizontal_margin”

    android:paddingTop=”@dimen/activity_vertical_margin”

    android:paddingBottom=”@dimen/activity_vertical_margin” tools:context=”.MainActivity”>

    <VideoView

        android:id=”@+id/videoView”

        android:layout_width=”fill_parent”

        android:layout_height=”fill_parent” />

</RelativeLayout>

调用VideoView 的如下两个方法来加载指定的视频

setVideoPath(String path);

setVideo(Url url);

最后调用VideoView的start(),stop(),pause()来控制视频播放

package xiaocool.net.videotest;

import android.graphics.PixelFormat;
import android.os.Environment;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.MediaController;
import android.widget.VideoView;

import java.io.File;

public class MainActivity extends ActionBarActivity {
private VideoView videoView;
private MediaController mediaController;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
//VID20150324130132.mp4
videoView=(VideoView)this.findViewById(R.id.videoView);
//创建MediaController对象
mediaController=new MediaController(this);
String path = Environment.getExternalStorageDirectory() + “/”;
String name = path + “VID20150324130132.mp4”;
File video=new File(name);
if(video.exists()){
videoView.setVideoPath(video.getAbsolutePath());
videoView.setMediaController(mediaController);
mediaController.setMediaPlayer(videoView);
videoView.requestFocus();
}

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();

//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}

return super.onOptionsItemSelected(item);
}
}
