ImeAction Search is changed to Done after tapping on it

问题

I have an Edittext for searching on Listview.

I have set imeOption to 'IME_ACTION_SEARCH' so that soft-keyboard will show search key on it.

The problem is that when I tap on search key on keyboard if edittext contains no text in it, the search key changes to 'Done' instead of dismissing the keyboard.

If the Edittext contains some text in it the search key works well.

In your XML layout file you can set

<EditText android:imeOptions="actionSearch" />

Or in your Java source file you could do

yourTextField.setImeOptions(EditorInfo.IME_ACTION_SEARCH);

Then you can override the listener for the search event.

yourTextField.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) { 
            //if textfield value is empty then close keyboard.
            //else call your search function.
        }
    }
});

you should do this to your edittext in xml

     android:imeOptions="actionSearch|actionSearch"

this will show you search button always!

I found the problem behind this. It was happening because the OnEditorAction Listener was not properly set on Edittext. Since listener was not properly set call was not reaching onEditorAction() method.
