requestFocus not working

2019-02-17 07:32发布

<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?

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

android:windowSoftInputMode="stateAlwaysVisible"

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

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

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();
    }
}

To do this in code, in your Activity:

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

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);
