推荐答案

有一件事情，你能做的就是声明一个全局变量安勤它会告诉你这是最后一次选择的EditText 通过使用 onTouchListener ，然后根据安勤，您可以通过设置按钮单击文本价值的EditText上。希望你能理解。

One thing that you can do is declare a global variable evalue which will tell you which is the last selected EditText by using onTouchListener and then based on the value of evalue, you can set the text value to the edittext by button click. hope you understood.

在$ C $下它可以如下：

the code for it can be as follow:

EditText e1,e2;
    Button b1,b2;
    String evalue;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        e1=(EditText)findViewById(R.id.editText1);
        e2=(EditText)findViewById(R.id.editText2);
        b1=(Button)findViewById(R.id.button1);
        b2=(Button)findViewById(R.id.button2);

        e1.setOnTouchListener(new View.OnTouchListener()
        {
            public boolean onTouch(View arg0, MotionEvent arg1)
            {
                evalue="1";
                return false;
            }
        });

        e2.setOnTouchListener(new View.OnTouchListener()
        {
            public boolean onTouch(View arg0, MotionEvent arg1)
            {
                evalue="2";
                return false;
            }
        });
        b1.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View arg0) {
                if(evalue=="1")
                {
                    e1.setText("yes");
                }
                if(evalue=="2")
                {
                    e2.setText("yes");
                }
            }
        });


        b2.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View arg0) {
                if(evalue=="1")
                {
                    e1.setText("No");
                }
                if(evalue=="2")
                {
                    e2.setText("No");
                }
            }
        });

    }
