Android实现完整游戏循环的方法

本文实例讲述了Android实现完整游戏循环的方法。分享给大家供大家参考。具体如下：

1. DroidzActivity.java：

package net.obviam.droidz;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.Window;import android.view.WindowManager;public class DroidzActivity extends Activity {  /** Called when the activity is first created. */ private static final String TAG = DroidzActivity.class.getSimpleName();  @Override  public void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    // requesting to turn the title OFF    requestWindowFeature(Window.FEATURE_NO_TITLE);    // making it full screen    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);    // set our MainGamePanel as the View    setContentView(new MainGamePanel(this));    Log.d(TAG, "View added");  } @Override protected void onDestroy() { Log.d(TAG, "Destroying..."); super.onDestroy(); } @Override protected void onStop() { Log.d(TAG, "Stopping..."); super.onStop(); }}

2. MainThread.java：

package net.obviam.droidz;import android.util.Log;import android.view.SurfaceHolder;public class MainThread extends Thread { private static final String TAG = MainThread.class.getSimpleName(); private SurfaceHolder surfaceHolder; private MainGamePanel gamePanel; private boolean running; public void setRunning(boolean running) { this.running = running; } public MainThread(SurfaceHolder surfaceHolder, MainGamePanel gamePanel) { super(); this.surfaceHolder = surfaceHolder; this.gamePanel = gamePanel; } @Override public void run() { long tickCount = 0L; Log.d(TAG, "Starting game loop"); while (running) {  tickCount++;  // update game state  // render state to the screen } Log.d(TAG, "Game loop executed " + tickCount + " times"); }}

3. MainGamePanel.java：

package net.obviam.droidz;import android.content.Context;import android.graphics.Canvas;import android.view.MotionEvent;import android.view.SurfaceHolder;import android.view.SurfaceView;public class MainGamePanel extends SurfaceView implements SurfaceHolder.Callback { private MainThread thread; public MainGamePanel(Context context) { super(context); getHolder().addCallback(this); // create the game loop thread thread = new MainThread(); setFocusable(true); } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { } @Override public void surfaceCreated(SurfaceHolder holder) { thread.setRunning(true); thread.start(); } @Override public void surfaceDestroyed(SurfaceHolder holder) { boolean retry = true; while (retry) {  try {  thread.join();  retry = false;  } catch (InterruptedException e) {  // try again shutting down the thread  } } } @Override public boolean onTouchEvent(MotionEvent event) { return super.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas) { }}

希望本文所述对大家的Android程序设计有所帮助。
