Android多媒体开发笔记[1]-- 利用Su易做图ceView + MediaPlayer开发最简单的视频播放器

利用android SDK 提供的接口开发最简单的视频播放demo。
接下来贴出main.xml的源码:
[html]
<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" >

    <Su易做图ceView
        android:id="@+id/su易做图ceView1"
        android:layout_width="wrap_content"
        android:layout_height="360dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true" />

</RelativeLayout>

接下来贴出程序源码：
[java]
package com.example.su易做图cemediaplayer;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.view.Menu;
import android.view.Su易做图ceHolder;
import android.view.Su易做图ceView;
import android.view.Su易做图ceHolder.Callback;

public class Su易做图ceMediaPlayer extends Activity {

    Su易做图ceView su易做图ceView;
    MediaPlayer mediaPlayer;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_su易做图ce_media_player);

        mediaPlayer=new MediaPlayer();
        su易做图ceView=(Su易做图ceView) this.findViewById(R.id.su易做图ceView1);

        su易做图ceView.getHolder().addCallback(new Callback() {
            @Override
            public void su易做图ceDestroyed(Su易做图ceHolder holder) {

            }
            @Override
            public void su易做图ceCreated(Su易做图ceHolder holder) {
                //开始播放
                play();
            }
            @Override
            public void su易做图ceChanged(Su易做图ceHolder holder, int format, int width,
                            int height) {

            }
    });
}

    private void play() {
    try {
            String path = Environment.getExternalStorageDirectory().getPath()+"/Movies/run_to_you.3gp";
            mediaPlayer.setDataSource(path);
            //把视频画面输出到Su易做图ceView
            mediaPlayer.setDisplay(su易做图ceView.getHolder());
            mediaPlayer.prepare();
            //开始播放
            mediaPlayer.start();
    } catch (Exception e) {
            // TODO: handle exception
    }
}

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_su易做图ce_media_player, menu);
        return true;
    }
}
