I am trying to set focus on a LinearLayout view when returning to an activity from another activity. The scenario:
I have one activity with a bunch of LinearLayout items (with stuff in them), some of which are text, others photos. Let's say the top most of 20 is a TextView and the rest are photos. When I leave this activity (to take a picture), activity goes to the top of the list where the TextView is - no matter what I do.
How do I force the focus back on the item that I was on before the new activity was triggered?
I have already tried this with no success:
I am currently trying to force the focus by remembering the previous view without success (though I can see the code being executed). The in my main activity:
@Override
public void onResume() {
super.onResume();
// See if we had a field with focus previously...
if (mPreviousView != null) {
if (mPreviousView.isFocusable()) {
mPreviousView.requestFocus();
}
}
}
...
@Override
protected void onPause() {
super.onPause();
mPreviousView = this.getCurrentFocus();
}
I am dynamically setting the focus in the LinearLayout:
private void initialize() {
LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.field_photo_picker, this);
// To allow focus to be returned to control after taking photo
this.setFocusableInTouchMode(true);
this.setFocusable(true);
this.setClickable(true);
And finally the XML for the LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:paddingBottom="5dp">
<TextView
android:id="@+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:textStyle="normal"
android:text="" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="@+id/photoValue"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:textSize="17sp"
android:textStyle="normal"
android:gravity="right|center_vertical"
android:layout_weight="1"
android:layout_marginRight="5dp"
android:text="" />
<ImageButton
android:id="@+id/photoPicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/form_photo"
android:padding ="5dp"
android:gravity="center_vertical"
android:focusableInTouchMode="false"
android:background="?android:attr/selectableItemBackground"
android:layout_weight="0"
/>
</LinearLayout>
<View
android:layout_marginTop="8dp"
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="@color/grey" />
</LinearLayout>
</merge>
make your textview
and other views focusable
, you made this.setFocusable(true);
which doesn't make sense
