How to clear the text in edittext

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

Here i开发者_开发知识库s my code:

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

  }
}

---

Use editText.getText().clear().

---

If using Kotlin, try:

editText.text.clear()

Extension Solution

Alternatively, you can add a small extension function to make it even simpler.

editText.clear()

fun EditText.clear() {
    text.clear()
}

---

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

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

---

you can use EditText.setText("");

---

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

---

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

String content = textValue.toString();
db.updatePicDes(content,lastSnapId);
editText.setText("");
