Android闪屏的简单做法

public class SplashActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//修改标题栏 背景
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
Intent intent =new Intent(SplashActivity.this,LoginActivity.class);
startActivity(intent);
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_in);
}}, 3000);
}
}
