I have a number of EditText elements in my page along with two buttons. I want the user to touch on any one EditText field and click any button to insert a certain value into that very EditText field they touched. Giving input using the keypad is not allowed. Please help me to do this.

你可以做的一件事是聲明一個全局變量evalue，它會告訴你哪個是最后選擇的EditText通過使用onTouchListener，然后根據evalue的值，可以通過按鈕點擊將文本值設置為edittext.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.

代碼如下:

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");
                }
            }
        });

    }

這是一個邏輯編碼.. 不符合標準.. 如果您找到更好的編碼.然后使用它.謝謝.

Its a logical coding.. not upto the mark.. if you find a better one. then use it. thank you.
