android 页面停几秒后跳转

  new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent intent = new Intent(MainActivity.this,
                        ExampleActivity.class);
                startActivity(intent);
            }

        }, SPLASH_DISPLAY_LENGHT);

         //实现等待几秒后跳转，方法二
         final Intent localIntent = new Intent(this, ExampleActivity.class);
         Timer timer = new Timer();
         TimerTask tast = new TimerTask() {
             @Override
             public void run() {
                 startActivity(localIntent);
             }
         };
         timer.schedule(tast, SPLASH_DISPLAY_LENGHT);
