暂时用过的是2个，以后还会补充....

方法一：

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main_activity);
		//自动跳转
		new Handler().postDelayed(new Runnable() {
            public void run() {
                    Intent mainIntent = new Intent(MainActivity.this,
                                    LoginActivity.class);
                    MainActivity.this.startActivity(mainIntent);
                    MainActivity.this.finish();
                    overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);
            }
    }, 5000);
		
	}

方法二：

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		final Intent localIntent=new Intent(MainActivity.this,SecondActivity.class);
		  Timer timer=new Timer();
		  TimerTask tast=new TimerTask()
		  {
		   @Override
		   public void run(){
		    startActivity(localIntent);
		   }
		  };
		  timer.schedule(tast,3000);
	}
