fragment在水平/垂直时的应用

直接看代码

 public class MainActivity extends Activity {
 
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
 
 /*        Fragment1 fragment1 = new Fragment1();
         Fragment2 fragment2 = new Fragment2();
 
         FragmentManager fragmentManager = getFragmentManager();
         FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
         fragmentTransaction.add(R.id.mainLayout, fragment1, "fragment1");
         fragmentTransaction.add(R.id.mainLayout, fragment2, "fragment2");
 
         fragmentTransaction.commit();*/
 
         Point size = new Point();
         this.getWindowManager().getDefaultDisplay().getSize(size);
         int width = size.x;
         int height = size.y;
         if (width > height) {//比较显示窗口的长宽
             Fragment1 fragment1 = new Fragment1();
             getFragmentManager().beginTransaction().replace(R.id.mainLayout, fragment1).commit();
         } else {
             Fragment2 fragment2 = new Fragment2();
             getFragmentManager().beginTransaction().replace(R.id.mainLayout, fragment2).commit();
         }
     }
 }

另外如下方法已经被谷歌deprecated

 Display display = getWindowManager().getDefaultDisplay();
         if (display.getWidth() > display.getHeight()) {
             Fragment1 fragment1 = new Fragment1();
             getFragmentManager().beginTransaction().replace(R.id.main_layout, fragment1).commit();
         } else {
             Fragment2 fragment2 = new Fragment2();
             getFragmentManager().beginTransaction().replace(R.id.main_layout, fragment2).commit();
         }
