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) {
 }
}
