Okay I got the "Source" of the error: the try and catch returned that the
Null Pointer Exception derives from this part as you already suspected:
ViewStub stub = (ViewStub) findViewById(R.id.stub_exposure);
importStub = stub.inflate();
But I don't understand why it should be null as I followed the examples I
found on the web... e.g. this here:
http://developer.android.com/reference/android/view/ViewStub.html
And this is the code in the xml, in which I call the ViewStub:
<ViewStub
android:id="@+id/stub_exposure"
android:inflatedId="@+id/stub_exposure_view"
android:layout="@layout/exposureview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#77000000">
</ViewStub>
And here is the according layout xml for the inflated View, the
exposureview.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@+String/hello"
></TextView>
<SeekBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:thumb="@drawable/seek_thumb"
android:progress="50"
android:max="100">
</SeekBar>
</RelativeLayout>
