My FloatingActionButton does not work. In my application I have a fragment and two tabs. In one of the tabs, the floatingActionButton works, the other does not. This is the main fragment layout, where the button is located:
<!-- The navigation drawer -->
<ListView android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="@color/actionbar"/>
<!-- The main content view -->
<RelativeLayout

android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".WorkRequestOpenTabs">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">

<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"

<io.codetail.widget.RevealFrameLayout

android:layout_height="match_parent">

</io.codetail.widget.RevealFrameLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/appbar"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_gravity="end|bottom"
android:layout_margin="@dimen/fab_margin"
android:src="@android:drawable/ic_dialog_email" />
</RelativeLayout>
This is the Aba (photos) code, where I need to adjust an action for the button:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
Log.i(this.getClass().getCanonicalName(), "###### onCreateView");
rootView = inflater.inflate(R.layout.tabworkrequestdocuments, container, false);
FloatingActionButton fab = (FloatingActionButton) getActivity().findViewById(R.id.fab);
fab.bringToFront();
if(fab != null) {
fab.setImageResource(R.drawable.add_sign);
fab.setVisibility(View.VISIBLE);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
addDocument();
}
});
}
return rootView;
}
