防止onClick方法運行一段時間

Question

我有一個簡單的多媒體應用程序，覆蓋從上到下的屏幕70％的百分比我有一個ImageView小部件，並在另一個30％的屏幕上我有10個按鈕，每個按鈕都會在ImageView小部件內部觸發一個動畫。

問題是，如果我點擊例如按鈕1，然後立即按下按鈕2，則按鈕1的動畫將停止，並且按鈕2的動畫將開始。如何在當前動畫播放時禁用10個按鈕？動畫完成後，我怎樣才能啓用按鈕？

我試着讓程序與thread.sleep（animationlenght）和TimeUnit.MILLISECONDS.sleep（animationlenght）一起睡，但它並不妨礙程序運行其他onClick事件。

package com.example.ticutu.croco; 
import android.app.Activity;enter code here 
import android.graphics.drawable.AnimationDrawable; 
import android.media.MediaPlayer; 
import android.os.Bundle;

Answer 1

您應該在動畫運行時禁用所有按鈕，因此請在活動中創建對按鈕的引用，並在需要時將其禁用。

可以使用的方法，如該檢查當動畫結束，並重新啓用按鈕：

private void checkIfAnimationDone(AnimationDrawable anim){ 
    final AnimationDrawable a = anim; 
    int timeBetweenChecks = 300; 
    Handler h = new Handler(); 
    h.postDelayed(new Runnable(){ 
     public void run(){ 
      if (a.getCurrent() != a.getFrame(a.getNumberOfFrames() - 1)){ 
       checkIfAnimationDone(a); 
      } else{ 
       //here re-enable your buttons 
      } 
     } 
    }, timeBetweenChecks); 
};
