Question

我是Android Studio新手。我想在按钮的动画和第二个活动的打开之间放置延迟，这样动画就会运行，然后会打开splashActivity。

    btn.setOnClickListener(new View.OnClickListener(){
        public void onClick(View arg0){
            Animation anim4 = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.splash_anim);
            btn.startAnimation(anim4);

            startActivity(new Intent(MainActivity.this, splashActivity.class));
        }
    });

Answer 1

int Delay_time_of_animation = 500;

btn.setOnClickListener（new View.OnClickListener（）{ public void onClick（查看arg0）{

Animation anim4 = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.splash_anim);
            btn.startAnimation(anim4);

 new Handler().postDelayed(new Runnable() {
                      @Override
                      public void run() {

                          startActivity(new Intent(MainActivity.this, splashActivity.class));
                      }
                  }, Delay_time_of_animation);

  }
    });

Answer 2

我使用本机java Timer来延迟。如果你想在两种方法之间延迟，那么你必须以毫秒为单位传递延迟时间。

int DELAY_TIME=2000

    //start your animation
    new Timer().schedule(new TimerTask() {          
        @Override
        public void run() {
   //this code will run after the delay time which is 2 seconds.
        startActivity(new Intent(MainActivity.this, splashActivity.class));
        }
    }, DELAY_TIME);

2000毫秒意味着你可以增加2秒的时间

一种方法的两个功能之间的延迟
