OnClickListener listens only on the second time

问题

I have an editText and have added an onClickListener to it. In the click method I am just clearing the text. When I click the editText first time the keypad pops up. But it is not going into the onClick method. The second time when I click it it is called and clears the text.

qtyEditTxt=(EditText)findViewById(R.id.qtyet);
qtyEditTxt.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                qtyEditTxt.setText("");             
            }
        });

I saw a question with an answer stating to make android:focusableInTouchMode to false. But then I will not be able to enter the text. Kindly help me with this

回答1:

How about focus?

final EditText qtyEditTxt= (EditText) findViewById(R.id.qtyet);
qtyEditTxt.setOnFocusChangeListener(new OnFocusChangeListener()
{
    @Override
    public void onFocusChange(View v, boolean isFocus) 
    {
        if (isFocus)
        {
            qtyEditTxt.setText("");             
        }
    }
});

Edited:

Default text? There you go :)

android:hint="Enter Quantity"

The behavior you are trying to have is very similar with an already existing feature of EditText.

Take a look at: http://developer.android.com/reference/android/widget/TextView.html#attr_android:hint

ClickListener is not a good choice for editText . use

editText.setOnEditorActionListener(new TextWatcher() {

            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // TODO Auto-generated method stub

            }

            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub

            }

            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub

            }
        })
    }

Just add <requestFocus /> right after closing tag of EditText in your layout.xml file
