手机上播放视频 Android VideoView

<pre class="java" name="code"><pre name="code" class="java"><span style="font-size:18px;"><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"
tools:context="com.zhangli.Video.MainActivity" >
<VideoView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/video"/>
</RelativeLayout>

2）在java代码中给VideoView设置文件目录，然后start播放:

<pre class="java" name="code">package com.zhangli.Video;
import java.io.File;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.widget.VideoView;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

VideoView videoView = (VideoView) findViewById(R.id.videoView);

// 获得的path等于:/storage/emulated/0/DCIM
File path = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);

// 拼接完整路径
File f = new File(path, "/Camera/test.mp4");

// 此时的f.getAbsolutePath()=/storage/emulated/0/DCIM//\Camera/test.mp4
videoView.setVideoPath(f.getAbsolutePath());

// 开始播放视频
videoView.start();

// VideiView获焦点
// videoView.requestFocus();
}
}

<pre class="java" name="code">uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
