Android's RelativeLayout Unit Test setup
- by dqminh
i'm trying to write an unit test for my Android's RelativeLayout. Currently, my testcode setup is as follow:
public class SampleRelativeLayoutTest extends AndroidTestCase {
private ViewGroup testView;
private ImageView icon;
private TextView title;
@Override
protected void setUp() throws Exception {
super.setUp();
// inflate the layout
final Context context = getContext();
final LayoutInflater inflater = LayoutInflater.from(context);
testView = (ViewGroup) inflater.inflate(R.layout.sample_layout,
null);
// manually measure and layout
testView.measure(500, 500);
testView.layout(0, 0, 500, 500);
// init variables
icon = (ImageView) testView.findViewById(R.id.icon);
title = (TextView) testView.findViewById(R.id.title);
}
However, I encountered NullPointerException with the following stack trace
java.lang.NullPointerException
at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:427)
at android.view.View.measure(View.java:7964)
at com.dqminh.test.view.SampleRelativeLayoutTest.setUp(SampleRelativeLayoutTest.java:33)

at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:430)
at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447)
What should I change in my setUp() code to make the test run properly ?
