我正在開發一款坦克游戲，我有一個TextView代表射擊的游戲?，F在我想TextView在特定點顯示 并在一秒鐘后將其刪除，看起來鏡頭一步一步走得更遠。但是，當我添加倒計時或 a 時，Thread.sleep程序會停止一秒鐘，但TextView不會消失。我想將 TextView 移動到屏幕上，并且在 for 循環的每次迭代之后我想等待一秒鐘，然后再次重新排列它？這是代碼： public void shot(float power, float winkel, Button button) { if(winkel>90) { winkel = winkel - 10; }else if(winkel<90){ winkel = winkel +10; } for (double i = 0; i<100;i = i+ 1) { final TextView textView = new TextView(context); textView.setText("."); double x = tanks.get(currentTank).getxPos()+(i*power*Math.cos(winkel *(Math.PI/180))); double y = tanks.get(currentTank).getyPos()+(-1*(i*power*Math.sin(winkel *(Math.PI/180)))); double gravity = (-1*((9.81/2)*Math.pow(i,2))); y = (y-gravity); textView.setX((float) x); textView.setY((float) y); layout.addView(textView); for (int j = 0;j<tanks.size();j++){ if(textView.getX()>tanks.get(j).getxPos()&&textView.getX()<tanks.get(j).getxPos()+100){ if(textView.getY()>tanks.get(j).getyPos()&&textView.getY()<tanks.get(j).getyPos()+100){ float k = tanks.get(j).getxPos()-textView.getX(); if(k<0){ k = k*-1; } makeDamage(k,tanks.get(j)); } } } new CountDownTimer(2000,1000){ @Override public void onTick(long millisUntilFinished) { } @Override public void onFinish() { layout.removeView(textView); } }.start(); } newTurn(); }我想在添加一秒鐘后暫停程序TextView并將其刪除。程序停止，但TextView直到 for 循環完成才消失。然后全部TextViews消失。

問題解決了： 我已經添加了數組中的所有位置，然后這個
public void drawShot(final Button firework, final ArrayList<TextView> toDraw){
final int[] i = {0};
final Handler mHandler = new Handler();
firework.setOnClickListener(new View.OnClickListener() {
@RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
@Override
public void onClick(View v) {
firework(firework,toDraw.get(i[0]).getX(),toDraw.get(i[0]).getY());
}
});
Runnable runnable = new Runnable() {
@Override
public void run() {
layout.addView(toDraw.get(i[0]));
if(!check(toDraw.get(i[0]))) {
mHandler.postDelayed(this, (long) 1);
}
i[0]++;
}
};
// start it with:
mHandler.post(runnable);
}

可能需要在主線程上運行刪除命令
Handler mainHandler = new Handler(context.getMainLooper());
Runnable myRunnable = new Runnable() {
@Override
public void run() {
layout.removeView(textView);
}
};
mainHandler.post(myRunnable);
