This article describes the method of implementing a complete game loop on Android. Share it for your reference. The details are as follows:
1. ：
package ;
import ;
import ;
import ;
import ;
import ;
public class DroidzActivity extends Activity {
/** Called when the activity is first created. */
private static final String TAG = ();
@Override
public void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
// requesting to turn the title OFF
requestWindowFeature(Window.FEATURE_NO_TITLE);
// making it full screen
getWindow().setFlags(.FLAG_FULLSCREEN, .FLAG_FULLSCREEN);
// set our MainGamePanel as the View
setContentView(new MainGamePanel(this));
(TAG, "View added");
}
@Override
protected void onDestroy() {
(TAG, "Destroying...");
();
}
@Override
protected void onStop() {
(TAG, "Stopping...");
();
}
}
2. ：
package ;
import ;
import ;
public class MainThread extends Thread {
private static final String TAG = ();
private SurfaceHolder surfaceHolder;
private MainGamePanel gamePanel;
private boolean running;
public void setRunning(boolean running) {
= running;
}
public MainThread(SurfaceHolder surfaceHolder, MainGamePanel gamePanel) {
super();
= surfaceHolder;
= gamePanel;
}
@Override
public void run() {
long tickCount = 0L;
(TAG, "Starting game loop");
while (running) {
tickCount++;
// update game state
// render state to the screen
}
(TAG, "Game loop executed " + tickCount + " times");
}
}
3. ：
package ;
import ;
import ;
import ;
import ;
import ;
public class MainGamePanel extends SurfaceView implements
{
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) {
(true);
();
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
boolean retry = true;
while (retry) {
try {
();
retry = false;
} catch (InterruptedException e) {
// try again shutting down the thread
}
}
}
@Override
public boolean onTouchEvent(MotionEvent event) {
return (event);
}
@Override
protected void onDraw(Canvas canvas) {
}
}
I hope this article will be helpful to everyone's Android programming design.
