public class FragmentsActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_fragments);
		
		FragmentManager fragmentManager = getFragmentManager();
		FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
		
		WindowManager wm = getWindowManager();
		Display d = wm.getDefaultDisplay();
		if(d.getWidth() > d.getHeight()){//landscape mode
			Fragment1 fragment1 = new Fragment1();
			//android.R.id.content活动的内容视图
			fragmentTransaction.replace(android.R.id.content, fragment1);
		}else{//portrait mode
