提供两个功能之间的时间差距

Question

如何在两个功能之间提供时间差距？

 public void onClick(View v) {
                r1.startAnimation(slide_up);

                Intent i = new Intent(Main_page.this, MainActivity.class);
                startActivity(i);
            }

Answer 1

为动画添加AnimationListener并在OnAnimationEnd()

中触发所需的方法

看看这个https://developer.android.com/reference/android/view/animation/Animation.AnimationListener.html

Answer 2

您可以使用Handler延迟

public void onClick(View v) {
                r1.startAnimation(slide_up);

                 new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        Intent i = new Intent(Main_page.this, MainActivity.class);
                        startActivity(i);
                    }
                }, 3000); // times in milliseconds

            }

第二种方式使用Animation.AnimationListener

示例代码

slideUpAnimation.setAnimationListener(new Animation.AnimationListener() {
    @Override
    public void onAnimationStart(Animation animation) {

    }

    @Override
    public void onAnimationEnd(Animation animation) {

       Intent i = new Intent(Main_page.this, MainActivity.class);
       startActivity(i);
    }

    @Override
    public void onAnimationRepeat(Animation animation) {

    }
});

第三种方式

slideUpAnimation.withEndAction(new Runnable() {
    @Override
    public void run() {
          Intent i = new Intent(Main_page.this, MainActivity.class);
          startActivity(i);
    }
});

Answer 3

试试这个

    slide_up.setAnimationListener(new AnimationListener() {

    @Override
    public void onAnimationStart(Animation arg0) {

    }

    @Override
    public void onAnimationRepeat(Animation arg0) {

    }

    @Override
    public void onAnimationEnd(Animation arg0) {

        Intent i = new Intent(Main_page.this, MainActivity.class);
        startActivity(i);
    }
});
