我的游戏有问题。每次玩家死亡时，都会出现一个屏幕，可以按“再试一次？”。然而当他按下这个按钮时，游戏崩溃并且安卓表示游戏已经终止。然后突然重启游戏。在重新启动之前，我无法弄清楚如何解决游戏崩溃的问题。这是触摸的代码：
if (game_finish == 1) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
System.out.println("Trying again!!");
activity.finish();
Intent myIntent = new Intent(getContext(), Game.class);
getContext().startActivity(myIntent);
}
}
我的面板，完成所有后台工作，如下所示：
public abstract class Panel extends SurfaceView implements
SurfaceHolder.Callback {
public Panel(Context context) {
super(context);
getHolder().addCallback(this);
runner = new RunnerThread(getHolder(), this);
setFocusable(true);
textPaint = new Paint();
textPaint.setColor(Color.BLUE);
textPaint.setTextSize(100);
textPaint.setFakeBoldText(true);
textPaint_1 = new Paint();
textPaint_1.setColor(Color.BLUE);
textPaint_1.setTextSize(50);
textPaint_1.setFakeBoldText(true);
}
protected void update() {
}
protected void drawPrimitives(Canvas canvas) {
}
protected boolean processTouch(MotionEvent event) {
return true;
}
public boolean addSprite(Sprite sprite) {
synchronized (runner.getSurfaceHolder()) {
return sprites.add(sprite);
}
}
@Override
public void onDraw(Canvas canvas) {
canvas.drawColor(Color.BLACK);
// draw all the panel's sprites
for (Sprite s : sprites) {
Rect destRect = new Rect(s.getLocation().x, s.getLocation().y,
s.getLocation().x + s.getSpriteWidth(), s.getLocation().y
+ s.getSpriteHeight());
canvas.save(); // save the position of the canvas
if (s.getRotation() < 0 | s.getRotation() > 0) {
canvas.rotate(s.getRotation(),
s.getLocation().x + (s.getSpriteWidth() / 2),
s.getLocation().y + (s.getSpriteHeight() / 2));
canvas.drawBitmap(s.getGraphic(), s.getSourceRect(), destRect,
null);
}
else {
canvas.drawBitmap(s.getGraphic(), s.getSourceRect(), destRect,
null);
}
canvas.restore();
}
drawPrimitives(canvas);
if (World.getGame_finish() == 1) {
paint.setARGB(128, 255, 255, 255);
rectF.set(0, 0, getMeasuredWidth(), getMeasuredHeight());
canvas.drawRect(rectF, paint);

提前谢谢！
答案 0 :(得分：1)
请务必在super.onPause() Game中拨打Activity，如下所示：
protected void onPause() {
// your cleanup code
super.onPause();
}
答案 1 :(得分：0)
com.example.game.Game Activity出现错误。 Android平台要求您从超类（在本例中为Activity）中调用某些方法，以使应用程序正常运行。
此错误消息告诉您在onPause()活动中覆盖了Game方法，如下所示：
@Override
protected void onPause() {
// your code
}
但是，该平台要求您从onPause()类调用默认的Activity实现。为此，请填写以下行：
super.onPause();
在Game.onPause()方法正文的开头。所以，你最终会得到代码：
@Override
protected void onPause() {
super.onPause();
// your code - same as before
}
答案 2 :(得分：0)
错误消息显示：
02-21 12:40:56.143: E/AndroidRuntime(29399): android.app.SuperNotCalledException: Activity {com.example.game/com.example.game.Game} did not call through to super.onPause()
请转到您的 com.example.game.Game 活动，然后在 onPause（）中执行以下操作：
protected void onPause(){
super.onPause();
// the rest of your code
}
