Android游戏开发学习笔记（三）：视频的播放

一、在命令行下输入mksdcard 512M c:\sdcard.img命令，创建sdcard镜像文件。
二、单击Eclipse的菜单命令“Window/Preferences”，打开Preferences窗口，在左侧选中“Android/Launch”，在右侧的“Default emulator options”中填入“-sdcard c:\sdcard.img”。
三、启动模拟器，切换视图到DDMS，找到“File Explorer”窗口，选中“mnt/sdcard”，执行右上角的“Push a file onto the device”，向sdcard中添加视频文件“qtfy01.3gp”。
四、编写项目的布局文件main.xml，代码如下：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <Su易做图ceView
        android:id="@+id/su易做图ceView"
        android:layout_width="fill_parent"
        android:layout_height="380px"
        />
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        >
        <Button
            android:id="@+id/play_btn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="播放"
            />
        <Button
            android:id="@+id/pause_btn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="暂停"
            />
    </LinearLayout>
</LinearLayout>
五、编写MainActivity.java代码。
package game.test;

import android.app.Activity;
import android.graphics.PixelFormat;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.Su易做图ceHolder;
import android.view.Su易做图ceView;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements Su易做图ceHolder.Callback {
    String path = "/sdcard/qtfy01.3gp";
    Button play_btn, pause_btn;
    boolean isPause = false;
    Su易做图ceHolder su易做图ceHolder;
    MediaPlayer mediaPlayer;
    Su易做图ceView su易做图ceView;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        play_btn = (Button) findViewById(R.id.play_btn);
        play_btn.setOnClickListener(video_listener);
        pause_btn = (Button) findViewById(R.id.pause_btn);
        pause_btn.setOnClickListener(video_listener);
        getWindow().setFormat(PixelFormat.UNKNOWN);
        su易做图ceView = (Su易做图ceView) findViewById(R.id.su易做图ceView);
        su易做图ceHolder = su易做图ceView.getHolder();
        su易做图ceHolder.addCallback(this);
        su易做图ceHolder.setFixedSize(176, 144);
        su易做图ceHolder.setType(Su易做图ceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        mediaPlayer = new MediaPlayer();
    }

    private OnClickListener video_listener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            switch (v.getId()) {
            case R.id.play_btn:
                isPause = false;
                playVideo(path);
                break;

            case R.id.pause_btn:
                if (isPause == false) {
                    mediaPlayer.pause();
                    isPause = true;
                } else {
                    mediaPlayer.start();
                    isPause = false;
                }
                break;
            }
        }

        private void playVideo(String path) {
            // TODO Auto-generated method stub
            if (mediaPlayer.isPlaying() == true) {
