从ImageView获取资源ID

Question

我正在努力开发一款小游戏.

我有一个ViewFlipper,在ImageViews中有50张图片(4张图片的随机频率).然后我有4个按钮,相同的4张图片可以出现在ViewFlipper中.

任务是在出现右图时单击右键.(当显示图片1时,必须按下按钮1,依此类推)

我的问题是我不知道如何获取显示的ImageView ID.

flipper.getCurrentView().getId() 

给我"-1"作为Id.但我想拥有"R.drawable.pic1"的ID

我的代码到目前为止:

我的装载机方法:

protected void loadPicturesIntoFlipper() {

    Random generator = new Random(); 
    pictures = new ArrayList();

    for(int i = 0; i < 50;i++){

        int number = generator.nextInt(4) + 1;

        if(number == 1){
            pic = R.drawable.pic1;
        }
        if(number == 2){
            pic = R.drawable.pic2;
        }
        if(number == 3){
            pic = R.drawable.pic3;
        }
        if(number == 4){
            pic = R.drawable.pic4;
        }

        pictures.add(pic);  
    }


    for(int i=0;i<pictures.size();i++)
    {

        setFlipperImage((Integer) pictures.get(i));
    }



}

我的插入方法:

private void setFlipperImage(int res) {

    image = new ImageView(getApplicationContext());
    image.setBackgroundResource(res);
    flipper.addView(image);
}

我的检查方法:

protected void check(int number, int id) {
    int code = 0;;

    if(number == 1){
        code = R.drawable.button_tip_finder;
    }
    if(number == 2){
        code = R.drawable.button_about_us;
    }
    if(number == 3){
        code = R.drawable.button_power_calculator;
    }
    if(number == 4){
        code = R.drawable.button_powerpedia;
    }



    if(code == id){
        test.setText(""+id);
    }
    else{
        test.setText(""+id);
    }


}

我称之为:

 button1.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {
                check(1,flipper.getCurrentView().getId());
                flipper.showNext();

                }
            });

Answer 1

像这样做:

private void setFlipperImage(int res) {
    image = new ImageView(getContext());
    image.setBackgroundResource(res);
    image.setTag(res); //<------
    flipper.addView(image);
}

然后:

button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                check(1,(Integer)flipper.getCurrentView().getTag());//<----
                flipper.showNext();
            }
        });

else请在您的所有代码中使用BTW ,例如:

 if(number == 1){
      pic = R.drawable.pic1;
 } else if(number == 2){
      pic = R.drawable.pic2;
 }  else if(number == 3){
       pic = R.drawable.pic3;
 }
