How do I make an Android EditView 'Done' button and hide the keyboard when clicked?

Question

First you need to set the android:imeOptions attribute equal to actionDone for your target EditText as seen below. That will change your ‘RETURN’ button in your EditText’s soft keyboard to a ‘DONE’ button.

<EditText 
    android:id="@+id/edittext_done"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="Enter some text"
    android:imeOptions="actionDone"
    android:singleLine="true"
    />

Use TextView.setImeOptions and pass it actionDone. like textView.setImeOptions(EditorInfo.IME_ACTION_DONE);

Include both imeOptions and singleLine:

<EditText 
   android:id="@+id/edittext_done"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:imeOptions="actionDone"
   android:singleLine="true"
   />

android:imeActionLabel="Done" 
android:singleLine="true"

In the XML file works just fine. But this will also cause the editText to keep typing in a single line which you may not want. So adding following to your code will make sure that you won't end up typing everything on a single line.

mainText.setHorizontallyScrolling(false);
mainText.setMaxLines("Maximum integer value that you want to provide");

For getting the done Button

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

and

android:inputType="text" in the xml

For handling on done clicked from keyboard

    editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event){
            if(actionId == EditorInfo.IME_ACTION_DONE){
                // Your action on done
                return true;
            }
            return false;
        }
    });

`

Use this:

android:singleLine="true"

Use These two lines to your EditText

android:imeActionLabel="Done"
android:singleLine="true"

or you can achieve it Programmatically by this line.

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);
