How to set focus on a view when a layout is created and displayed?

Question

Currently, I have a layout which contains a Button, a TextView and an EditText. When the layout is displayed, the focus will be automatically put on the EditText, which will trigger the keyboard to show up on Android phone. It is not what I want. Is there any way that I can set the focus on TextView or on nothing when a layout is displayed? Thanks.

Answer 1

Set focus: The framework will handled moving focus in response to user input. To force focus to a specific view, call requestFocus()

Answer 2

I tried requestFocus(), but it doesn't work. See the code below:

public class HelloAndroid extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

       LinearLayout mainVw = (LinearLayout) findViewById(R.id.main_layout);

       LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
               LinearLayout.LayoutParams.FILL_PARENT,
               LinearLayout.LayoutParams.WRAP_CONTENT);

       EditText edit = new EditText(this);
       edit.setLayoutParams(params);
       mainVw.addView(edit);

       TextView titleTv = new TextView(this);
       titleTv.setText("test");
       titleTv.setLayoutParams(params);
       mainVw.addView(titleTv);

       titleTv.requestFocus();
   }
}

The focus still goes to the EditText when the page is displayed. How to make the focus to be on the TextView?

Answer 3

Try

comp.requestFocusInWindow();

Answer 4

Set android:focusable="true" in your

Answer 5

The last suggestion is the correct solution. Just to repeat, first set android:focusable="true" in the layout xml file, then requestFocus() on the view in your code.

Answer 6

i think a text view is not focusable. Try to set the focus on a button for example, or to set the property focusable to true.
