How can I get a "done" button in softkeyboard?

add this to your EditText xml:

android:imeOptions="actionDone"

or, to set it from code:

yourEditText.setImeOptions(EditorInfo.IME_ACTION_DONE);

for more, read this

In my Intel x86 Emulator at least, the "Done" key appears only if you specify the input type: "phone", "number", "text", "textPassword", ... with android:inputType. If you don't specify any or you set "textMultiLine", "Done" does not appear.

android:imeOptions="actionDone"

and

editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

seem useless, since they don't change anything either in the first case (where "Done" appears anyway) or in the in the second case (since "Done" keeps not appearing) !

Using my Galaxy S2 phone

For the code below, each EditText will have a Return button that adds a new line:

EditText editText = new EditText(this);

For the code below, each EditText will have a Next button that navigates to the next field and the last one will have Done button that will dismiss the keyboard:

EditText editText = new EditText(this);
editText.setInputType(InputType.TYPE_CLASS_TEXT);

For the code below, no change, each EditText has a Return button:

EditText editText = new EditText(this);
editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

For the code below, all EditText will have a Done button and all will dismiss the keyboard.

    EditText editText = new EditText(this);
    editText.setInputType(InputType.TYPE_CLASS_TEXT);
    editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

For layouts use code below:

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:inputType="text"
    android:imeOptions="actionDone"/>
