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();  
        }
