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

Posted by: admin November 30, 2017 Leave a comment

Questions:

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?

Answers:

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

This works:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

You can try just hidding the keyboard. Something like this:

InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

To set focus, delay the requestFocus() using a Handler.

private Handler mHandler= new Handler();

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);

     mHandler.post(
       new Runnable() 
       {
          public void run() 
          {
            titleTv.requestFocus();
          } 
       }
     );
   }
}

None of the answers above works for me. The only (let’s say) solution has been to change the first TextView in a disabled EditText that receives focus and then add

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

in the onCreate callback to prevent keyboard to be shown. Now my first EditText looks like a TextView but can get the initial focus, finally.

Set android:focusable="true" in the layout xml file,
then requestFocus() on the view in your code

NO, it doesn’t work here.

Answers:

Set these lines to OnResume as well and make sure if focusableInTouch is set to true while you initialize your controls

<controlName>.requestFocus();

<controlName>.requestFocusFromTouch();

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.

Answers:

you can add an edit text of size “0 dip” as the first control in ur xml, so, that will get the focus on render.(make sure its focusable and all…)

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.

You can start by adding android:windowSoftInputMode to your activity in AndroidManifest.xml file.

<activity android:name="YourActivity"
          android:windowSoftInputMode="stateHidden" />

This will make the keyboard to not show, but EditText is still got focus. To solve that, you can set android:focusableInTouchmode and android:focusable to true on your root view.

<LinearLayout android:orientation="vertical"
              android:focusable="true"
              android:focusableInTouchMode="true"
              ...
              >
    <EditText
         ...
       />
    <TextView
         ...
       />
    <Button
         ...
       />
</LinearLayout>

The code above will make sure that RelativeLayout is getting focus instead of EditText

Questions:
Answers:

Focus is for selecting UI components when you are using something besides touch (ie, a d-pad, a keyboard, etc.). Any view can receive focus, though some are not focusable by default. (You can make a view focusable with setFocusable(true) and force it to be focused with requestFocus().)

However, it is important to note that when you are in touch mode, focus is disabled. So if you are using your fingers, changing the focus programmatically doesn’t do anything. The exception to this is for views that receive input from an input editor. An EditText is such an example. For this special situation setFocusableInTouchMode(true) is used to let let the soft keyboard know where to send input. An EditText has this setting by default. The soft keyboard will automatically pop up.

If you don’t want the soft keyboard popping up automatically then you can temporarily suppress it as @abeljus noted:

InputMethodManager inputManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

When a used clicks on the EditText it should show the keyboard, though.
