Question

我正在为平板电脑编写一个应用程序，在这种情况下，我连续有8个按钮，并且带有一些背景。现在，我想更改单击的唯一按钮以及所有8个按钮的背景。

我尝试制作可绘制的XML并处理按钮状态（如聚焦，按下），还尝试检查以防万一。但这仅会改变背景直到我按下它。这不是我的要求。因此，要实现这一点，我必须写出行数。

myDrawable

<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true"
        android:state_pressed="false"
        android:drawable="@drawable/background_white_with_black_border" />
    <item android:state_focused="true"
        android:state_pressed="true"
        android:drawable="@drawable/background_white_with_black_border" />
    <item android:state_focused="false"
        android:state_pressed="true"
        android:drawable="@drawable/background_all_corners_five_dp_solid_login_btn_blue" />
    <item android:drawable="@drawable/background_white_with_black_stroke" />
</selector>```

setting the above as buttons background didnt gave me result. So did this:

```button1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                button1.setBackground(getResources().getDrawable(R.drawable.background_all_corners_five_dp_solid_login_btn_blue));
                baySelected = "Bay1";
                button2.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));
                button3.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));
                button4.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));
                button5.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));
                button6.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));
                button7.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));
                button8.setBackground(getResources().getDrawable(R.drawable.background_white_with_black_stroke));```

有多个按钮时如何处理onClick的按钮背景？
