ゲームに問題があります。プレイヤーが死亡するたびに、「Try Again?」を押すことができる画面が表示されます。しかし、彼がこのボタンを押すと、ゲームがクラッシュし、Android はゲームが終了したと言います。そしていきなりゲーム再開。再起動する前にゲームがクラッシュする問題を解決する方法がわかりません。タッチのコードは次のとおりです。
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);
}
}
すべてのバックグラウンド作業が行われる My Panel は、次のようになります。
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.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);
