How to clear the text in edittext

问题

I want to clear the text in EditText after it has been saved in database.

Here is my code:

pictureDescription.addTextChangedListener(new TextWatcher()
{
  public void afterTextChanged(Editable textValue)
  {
    String content = textValue.toString();
    db.updatePicDes(content,lastSnapId);

  }
}

回答1:

Use editText.getText().clear().

回答2:

Just set it to empty string. I think it should do it.

EditText editText = (EditText)findViewById(R.id.edit_text);
editText.setText("");

回答3:

you can use EditText.setText("");

回答4:

You better do that in FocusChangedListener if you donot want it on clicking a button.
