你好，我有一个点击按钮和两个编辑文本的大问题，我用十二个按钮和两个编辑文本创建了自己的键盘，第一个编辑文本只允许输入数字，第二个允许输入数字并进行计算。我真正的问题是我不能只在第一个中输入第二个编辑文本。这是平局

        *********** *********
        *    1    * *   2   *   // These are EditTexts 
        *********** *********

        **************************
        *   7   *   8    *   9   *   
        **************************
        *   4   *   5    *   6   *  // These are Buttons
        **************************
        *   1   *   2    *   3   *
        **************************
        *   0   *   c    *   +   *
        **************************

(+) 此按钮进行计算并更改编辑文本的焦点

这也是代码：在此先感谢我将不胜感激任何帮助

您不想使用，因为hasFocus()将焦点从 View 当前拥有的任何视图中移开并将其提供给调用者。此外，您应该使用通用侦听器来减少重复代码，如下所示。requestFocus()requestFocus()

创建一个新的类变量：

OnClickListener addClickListener = new OnClickListener() {
    public void onClick(View v) {
        int number = Integer.parseInt(((Button) v).getText().toString());
        if(inJugada.hasFocus()) { // " == true" is implied
            playDisplayed += number;
        }else if(inValor.hasFocus()) {
            numberDisplayed += number;
        }
        updateTextField();
    }
};

并将此侦听器添加到您的 Buttons 0-9：

final Button bt0 = (Button) findViewById(R.id.btnNum0Id);
bt0.setOnClickListener(addClickListener);

// etc.
