This is a basic example of using a Fragment to achieve a master-detail type layout on tablets
The fragment is included using the diagram above. Tablets are detected by using two layout files:
/res/layout/activity_main.xml (phone layout)
/res/layout-sw600dp-land/activity_main.xml (tablet layout)
In the MainActivity class, a tablet can be detected by checking if a view in the xml exists and either starting the activity (phones) or include the Fragment (tablets)
// check if in dual view mode (fragment exists)
if (findViewById(R.id.fragmentLayout) == null) {
// standard phone display
Intent i = new Intent(this, DetailActivity.class);
this.startActivity(i);
} else {
// horisontal tablet mode
getFragmentManager()
.beginTransaction()
.replace(R.id.fragmentLayout, new DetailFragment()) // .replace or .add
.commit();
}
