requestFocus not working

Question

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="20dp" >

    <AutoCompleteTextView
        android:id="@+id/autocomplete_zone"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:dropDownVerticalOffset="0.2dp"
        android:ems="10"
        android:hint="@string/zone_hint"
        android:inputType="text"
        android:lines="1"
        android:maxLines="1"
        android:popupBackground="#00ffffff"
        android:textColor="#ffffff"
        android:textColorHint="#ffffff" >

        <requestFocus />
    </AutoCompleteTextView>

    <ProgressBar
        android:id="@+id/progressBar1"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignBottom="@id/autocomplete_zone"
        android:layout_alignRight="@id/autocomplete_zone"
        android:layout_alignTop="@id/autocomplete_zone"
        android:paddingBottom="5dp"
        android:visibility="invisible" />
</RelativeLayout>

In the above markup

<requestFocus />

does not work. The text view is not focused when the activity is started. Is this because of the progress bar which overlays the text view? Any ideas how to fix this?

Answer 1

I usually use the following to set the focus: Add following attributs to your xml-layout

<AutoCompleteTextView 
    android:focusable="true" 
    android:focusableInTouchMode="true"> 
</AutoCompleteTextView>

and set focus programmatically like

((AutoCompleteTextView) findViewById(R.autocomplete_zone)).requestFocus();

f.e. in onResume or onWindowChanged

public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);

    if (hasFocus) {
        ((AutoCompleteTextView) findViewById(R.autocomplete_zone)).requestFocus();
    }
}

Answer 2

None of the above worked for me... this is what I used

txtView.getParent().requestChildFocus(txtView,txtView);

Answer 3

Solved it! In manifest I added following to the activity:

android:windowSoftInputMode="stateAlwaysVisible"

Answer 4

You can try this in the code if you want to forcefully show the keyboard.

((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

then you can to use this code to close the keyboard:

((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(autocomplete_zone.getWindowToken(), 0);

Answer 5

To do this in code, in your Activity:

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

Answer 6

I think this is the only good workable solution.

If you want to requestFocus() after !hasFocus then you must do this with a delay because else you call requestFocus(), but after that the next control receives focus. So its important to understand the next control receives focus AFTER your requestFocus().

The solution is that next control receives focus, but after a delay of x milisecs goes back to the previous control. Its a near perfect trick because the next control receives focus for x millisecs. I did set 100 msecs for the delay but you could try a smaller delay, may be that works too.

/**
 * validate data of scan control when focus changed
 * @param view - view to get control from
 * @param subject - subject to validate
 * @param scanId - id of scan data
 * @param fromId - id of from control
 * @param articleId - id of article control
 * @return - return scan edit control
 */
EditText editTextFocusListener(View view, int subject, int scanId, int fromId, int articleId) {

    // select all data when having focus
    EditText editTextScan = view.findViewById(scanId);
    editTextScan.setSelectAllOnFocus(true);

    // when not valid keep focus on control until valid
    editTextScan.setOnFocusChangeListener((vw, hasFocus) -> {
        if (!hasFocus && !validateInput(subject, editTextScan, fromId, articleId))
            new Handler().postDelayed(() -> editTextScan.requestFocus(), 100);
    });

    // return scan from control
    return editTextScan;
}
