我的SplashScreenActivity存在问题,当我在手机上启动应用程序时,它显示白屏大约0.5秒. MainActitivy扩展了FragmentActivity,在AndroidManifest中,我将SplashScreenActivity声明为启动器和纵向模式作为screenorIEntation.

代码：

public class SplashScreenActivity extends Activity {@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    requestwindowFeature(Window.FEATURE_NO_Title);    setContentVIEw(R.layout.splashscreen);    randomSplash();    Thread splashscreen = new Thread() {        public voID run() {            try {                Thread.sleep(1000);                Intent mainScreen = new Intent("com.rm.jkrm.MAINACTIVITY");                startActivity(mainScreen);            } catch (InterruptedException e) {            } finally {                finish();            }        }    };    splashscreen.start();}private voID randomSplash(){    Random random = new Random();    int i = random.nextInt(4);    linearLayout ln = (linearLayout) findVIEwByID(R.ID.splashscreen);    switch(i){    case 1:         ln.setBackgroundResource(R.drawable.splash1);        break;    case 2:         ln.setBackgroundResource(R.drawable.splash2);        break;    case 3:         ln.setBackgroundResource(R.drawable.splash3);        break;    default:         ln.setBackgroundResource(R.drawable.splash0);        break;    }}}

XML：

 <?xml version="1.0" enCoding="utf-8"?> <linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID" androID:ID="@+ID/splashscreen" androID:layout_wIDth="match_parent" androID:layout_height="match_parent" androID:orIEntation="vertical"></linearLayout>

解决方法:

 Thread splashscreen = new Thread() {        public voID run() {            try {                Thread.sleep(1000);                Intent mainScreen = new Intent("com.rm.jkrm.MAINACTIVITY");                startActivity(mainScreen);            } catch (InterruptedException e) {            } finally {                finish();            }        }    };    splashscreen.start();

这是你的问题UI线程睡觉不是一个很好的主意使用处理程序而不是
我认为它也可能导致例外.

Handler h=new Handler();        h.postDelayed(new Runnable() {            public voID run() {                // Todo auto-generated method stub                startActivity(new Intent(Splash_Activity.this,Main_Activity.class));                finish();            }        }, 2000);    }
