Android實現自動換屏

Android實現自動換屏:

1. /**
2. * 獲取屏幕的方向
3. * @param activity
4. * @return
5. */
6. public static int screenOrient(Activity activity)
7. {
8. int orientation = activity.getRequestedOrientation();
9. if(orientation != ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
10. && orientation != ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
11. {
12. //寬>高為橫屏,反則為豎屏
13. WindowManager manager = activity.getWindowManager();
14. Display display = manager.getDefaultDisplay();
15. int height = display.getHeight();
16. int width = display.getWidth();
17. orientation = width > height?ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE:ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
18. }
19. return orientation;
20. }
    

1. /**
2. * 自動換屏的方法
3. * @param activity
4. * @param view
5. * @param Background_v
6. * @param Background_h
7. */
8. public static void autoBackground(Activity activity,View view,int Background_v, int Background_h)
9. {
10. int orient = screenOrient(activity);
11. if (orient == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
12. {
13. //縱向
14. view.setBackgroundResource(R.drawable.bg);
15. }else {
16. //橫向
17. view.setBackgroundResource(R.drawable.bg);
18. }
19. }
    

1. public void onCreate(Bundle savedInstanceState) {
2. super.onCreate(savedInstanceState);
3. requestWindowFeature(Window.FEATURE_NO_TITLE);
4. getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
5. setContentView(R.layout.main);
7. LinearLayout layout = (LinearLayout)findViewById(R.id.layout);
8. autoBackground(this, layout, R.drawable.bg, R.drawable.bg);
