這樣的Activity,你覺得在啟動的時候會卡頓嗎？

01 public class MainActivity extends Activity { 

02       

03     public void onCreate(Bundle savedInstanceState) { 

04         long l1=System.currentTimeMillis(); 

05         //Bitmap bit =  BitmapFactory.decodeFile("//sdcard//androidesk//data//splash//.jpg"); 

06         InputStream is = getResources().openRawResource(R.drawable.wone);     

07         try { 

08             Thread.sleep(1000 * 7); 

09         } catch (InterruptedException e) { 

10             e.printStackTrace(); 

11         } 

12         Bitmap bit = BitmapFactory.decodeStream(is);  

13         long l2=System.currentTimeMillis(); 

14         System.out.println("time cost:"+(l2-l1)); 

15           

16         setContentView(R.layout.activity_main); 

17         ImageView iView = (ImageView)findViewById(R.id.imageView1); 

18         iView.setImageBitmap(bit); 

19         super.onCreate(savedInstanceState); 

20     } 

21 }
