按下enter后如何清除edittext中的字符

Question

I am using the following code to clear edit text after enter is pressed, but its not working.

inText.setOnKeyListener(this);
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
    if ((event.getAction() == KeyEvent.ACTION_DOWN)) {
        if (keyCode == KeyEvent.KEYCODE_ENTER) {
            inText.setText("");
        }
        return true;
    }
    return false;
}

Answer 1

You should check if the onKey method is actually called and what key codes are delivered to it. It is possible that a different event than KEYCODE_ENTER is generated, depending on the input type of you EditText. You could also try using OnEditorActionListener instead of OnKeyListener.

Answer 2

try this:

inText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_DONE) {
                inText.setText("");
            }
            return false;
        }
    });
