Android：隨機從2個池中挑選圖像

-1

我有一個應用程序，我計劃在屏幕上顯示一些設計。過程如下：Android：隨機從2個池中挑選圖像

顯示從池1中隨機選取的圖像1秒;
顯示黑屏（1秒）
顯示從池2中隨機選取的圖像1秒;
顯示一個紅屏（等到按鈕被按下

重複1-4多次問題1：什麼是實現這樣的行爲，最好的做法我試圖用「動畫可繪製「，但據我所知，你不能從該xml中隨機選擇圖像？

問題2：效率如何？按照問題1中的描述進行試驗後，它顯示：」I/Choreographer：跳過59幀！應用程序可能在其主線程上做了太多工作。「 - >我需要多線程嗎？

最佳， tigercode

沒有代碼，沒有樂趣。 –

的人誰的興趣，這是我的解決方案:-)

final ImageView imageViewMeasurement = (ImageView) findViewById(measurement_image_view); 


    imageViewMeasurement.postDelayed(new Runnable(){ 
             @Override 
             public void run() { 
              imageViewMeasurement.setImageResource(R.color.colorGreyMeasuerementScreen); 
              Log.d("QuantifyDesign", "1. MeasurementScreen Default"); 
             }} 
      ,0); 

    imageViewMeasurement.postDelayed(new Runnable(){ 
             @Override 
             public void run() { 
              TypedArray images = getResources().obtainTypedArray(R.array.images_primes_1); 
              int chosenImageNumber = (int) (Math.random() * images.length()); 

              // setImageResource to the random chosenImageNumber 
              imageViewMeasurement.setImageResource(images.getResourceId(chosenImageNumber, R.color.colorGreyMeasuerementScreen)); 
              images.recycle(); 

              // Confirmation if the random generator picked a Number from the array 
              String chosenImageNumberTest = String.valueOf(chosenImageNumber); 
              Log.d("QuantifyDesignPrime", chosenImageNumberTest); 
              Log.d("QuantifyDesign", "2. MeasurementScreen Prime 16"); 
             }} 
      ,5000); 

    imageViewMeasurement.postDelayed(new Runnable(){ 
             @Override 
             public void run() { 
              imageViewMeasurement.setImageResource(R.color.colorBlackMeasurementScreen); 
              Log.d("QuantifyDesign", "3. MeasurementScreen Black Screen"); 
             }} 
      ,5750); 

    imageViewMeasurement.postDelayed(new Runnable(){ 
             @Override 
             public void run() { 
              TypedArray images = getResources().obtainTypedArray(R.array.images_target); 
              int chosenImageNumber = (int) (Math.random() * images.length()); 

              // setImageResource to the random chosenImageNumber 
              imageViewMeasurement.setImageResource(images.getResourceId(chosenImageNumber, R.color.colorGreyMeasuerementScreen)); 
              images.recycle(); 

              // Confirmation if the random generator picked a Number from the array 
              String chosenImageNumberTest = String.valueOf(chosenImageNumber); 
              Log.d("QuantifyDesignTarget", chosenImageNumberTest); 
              Log.d("QuantifyDesign", "4. MeasurementScreen Target 1"); 
             }} 
      ,6000); 

    imageViewMeasurement.postDelayed(new Runnable(){ 
             @Override 
             public void run() { 
              imageViewMeasurement.setImageResource(R.drawable.buttonklickmeasurement); 
              Button resetButtonLike=(Button)findViewById(R.id.button_like); 
              resetButtonLike.setVisibility(View.VISIBLE); //To set visible 
              Button resetButtonDislike=(Button)findViewById(R.id.button_dislike); 
              resetButtonDislike.setVisibility(View.VISIBLE); //To set visible 
              Log.d("QuantifyDesign", "5. MeasurementScreen Apell"); 
             }} 
      ,7000);

這裏是有趣：

我班（Gameactivity）和第一次嘗試與AnimationDrawable：

public class GameActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.game); 
     getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 

     /* ImageView */ 

     ImageView myAnimation = (ImageView) findViewById(R.id.spin_animation_left); 

     final AnimationDrawable myAnimationDrawable 
       = (AnimationDrawable) myAnimation.getDrawable(); 

     myAnimation.post(
       new Runnable() { 

        @Override 
        public void run() { 
         myAnimationDrawable.start(); 
        } 
       }); 

    } 

    /*Show Gameactivity always on fullscreen */ 

    @Override 
    public void onWindowFocusChanged(boolean hasFocas) { 
     super.onWindowFocusChanged(hasFocas); 
     View decorView = getWindow().getDecorView(); 
     if (hasFocas) { 
      decorView.setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_LAYOUT_STABLE 
          | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION 
          | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 
          | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar 
          | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar 
          | View.SYSTEM_UI_FLAG_IMMERSIVE); 
     } 


    } 

    @Override 
    public boolean dispatchKeyEvent(KeyEvent b) { 
     if (b.getKeyCode() == KeyEvent.KEYCODE_DPAD_LEFT) { 
      startActivity(new Intent(this,StartActivity.class)); 
     } 
     return super.dispatchKeyEvent(b); 
    }; 

}

在這裏，我的XML（其他時間，只是表示：「圖像池1" - 「圖像池2」，等...）：
