Android Studio：为 onClick imageButton 遍历 drawable 中的图像

Question

我目前设置了 8 个 imageButton，id 为 imageButton1 到 imageButton8。

当我单击特定按钮（例如 imageButton2）时，我想遍历名为 image1....image10 的可绘制文件夹中的图像，并为每次单击将图像设置为 imageButton。

我已经查看了各种 for 循环来解决这个问题，但它们无济于事。这是 for 循环尝试的片段：

ImageButton btn1, btn2, btn3, btn4, btn5, btn6, btn7, btn8;
ImageButton[] btns;
int[] drawables = new int[]{R.drawable.image1,R.drawable.image2,R.drawable.image3,R.drawable.image4,R.drawable.image5,R.drawable.image6,R.drawable.image7,R.drawable.image8};


@Override
protected void onCreate(Bundle savedInstanceState) {  

    btn1 = (ImageButton) findViewById(R.id.imageButton1);
    btn2 = (ImageButton) findViewById(R.id.imageButton2);
    btn3 = (ImageButton) findViewById(R.id.imageButton3);
    btn4 = (ImageButton) findViewById(R.id.imageButton4);
    btn5 = (ImageButton) findViewById(R.id.imageButton5);
    btn6 = (ImageButton) findViewById(R.id.imageButton6);
    btn7 = (ImageButton) findViewById(R.id.imageButton7);
    btn8 = (ImageButton) findViewById(R.id.imageButton8);

        btn1.setOnClickListener(this);
        btn2.setOnClickListener(this);
        btn3.setOnClickListener(this);
        btn4.setOnClickListener(this);
        btn5.setOnClickListener(this);
        btn6.setOnClickListener(this);
        btn7.setOnClickListener(this);
        btn8.setOnClickListener(this);
}


btns = new ImageButton[]{btn1, btn2, btn3, btn4, btn5, btn6, btn7, btn8};
}

int counter = 0;
        @Override
    public void onClick(View v)
        {

            counter ++;


            for (int i = 0; i < btns.length; i++)
            {


                if (v.getId() == btns[i].getId())
                {
                    if(counter ==8)
                    {
                        counter =0;
                    }

                        ((ImageButton)v).setImageResource(drawables[counter]);

                }

            }
}
}

另一个尝试是创建一个计数器来存储点击次数，并设置 if 语句根据每次点击更改图像。

这里的问题是考虑到我有多个按钮，它会创建大量代码。

最重要的是，当我运行在两个不同的按钮上执行此操作时，一旦我点击 imageButton1 几次，然后点击 imageButton2 几次，imageButton1 不再响应。

int counter =0;

        @Override
    public void onClick(View v)
        {
            counter++;


            switch(v.getId())
            {
                case R.id.imageButton1:
                    if(counter == 1){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
                        btn1.setImageResource(R.drawable.image1);
                        break;

                    }else if (counter == 2){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
                        btn1.setImageResource(R.drawable.image2);
                        break;

                    }else if (counter == 3){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
                        btn1.setImageResource(R.drawable.image3);

                        break;

                    }else if (counter == 4){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
                        btn1.setImageResource(R.drawable.image4);

                        break;
                    }else if (counter == 5){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);

                    }else if (counter == 6){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
                        btn1.setImageResource(R.drawable.image6);

                        break;

                    }else if (counter == 7){

                        ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
                        btn1.setImageResource(R.drawable.image7);

                        break;

试试这个

    int counter = 1;
    @Override
    public void onClick(View v)
    {
        switch(v.getId())
        {
            case R.id.imageButton1:
             ImageButton btn1 = (ImageButton) findViewById(R.id.imageButton1);
               if(counter == 1){
                    btn1.setImageResource(R.drawable.image1);
                }else if (counter == 2){
                    btn1.setImageResource(R.drawable.image2);
                }else if (counter == 3){
                    btn1.setImageResource(R.drawable.image3);
                }else if (counter == 4){
                    btn1.setImageResource(R.drawable.image4);
                }else if (counter == 5){
                    btn1.setImageResource(R.drawable.image5);
                }else if (counter == 6){
                    btn1.setImageResource(R.drawable.image6);
                }else if (counter == 7){
                    btn1.setImageResource(R.drawable.image7);
                }else if (counter == 8){
                    btn1.setImageResource(R.drawable.image8);
                }else if (counter == 9){
                    btn1.setImageResource(R.drawable.image9);
                }else if (counter == 10) {
                    btn1.setImageResource(R.drawable.image10);
                }

            counter = (counter % 10) + 1 ;
                break;
    }

Answer 2

只是一个建议。

也许您可以将按钮和图像资源声明为数组，然后循环遍历它们。

例如：

public class Sample extends Activity {

  ImageButton btn1, btn2, btn3, btn4, btn5, btn6, btn7, btn8;
  ImageButton[] btns;
  int[] drawables = new int[]{R.drawable.imageButton1,R.drawable.imageButton2,R.drawable.imageButton3,R.drawable.imageButton4,R.drawable.imageButton5,R.drawable.imageButton6,R.drawable.imageButton7,R.drawable.imageButton8};
  int[] origDrawables = new int[]{R.drawable.imageOrigButton1,R.drawable.imageOrigButton2,R.drawable.imageOrigButton3,R.drawable.imageOrigButton4,R.drawable.imageOrigButton5,R.drawable.imageOrigButton6,R.drawable.imageOrigButton7,R.drawable.imageOrigButton8};

  @Override
  public void onCreate(Bundle saveInstanceState) {
    btn1 = (ImageButton) findViewById(R.id.imageButton1);
    btn2 = (ImageButton) findViewById(R.id.imageButton2);
    btn3 = (ImageButton) findViewById(R.id.imageButton3);
    btn4 = (ImageButton) findViewById(R.id.imageButton4);
    btn5 = (ImageButton) findViewById(R.id.imageButton5);
    btn6 = (ImageButton) findViewById(R.id.imageButton6);
    btn7 = (ImageButton) findViewById(R.id.imageButton7);
    btn8 = (ImageButton) findViewById(R.id.imageButton8);

    btn1.setOnClickListener(this);
    btn2.setOnClickListener(this);
    btn3.setOnClickListener(this);
    btn4.setOnClickListener(this);
    btn5.setOnClickListener(this);
    btn6.setOnClickListener(this);
    btn7.setOnClickListener(this);
    btn8.setOnClickListener(this);

    btns = new ImageButton[]{btn1, btn2, btn3, btn4, btn5, btn6, btn7, btn8};
  }

  @Override
  public void onClick(View v) {
    for (int i = 0; i < btns.length; i++) {
      if (v.getId == btns[i].getId) {
        ((ImageButton)v).setImageResource(drawables[i]);
      } else {
        ((ImageButton)v).setImageResource(origDrawables[i]);
      }
    }
  }

}
