Android按钮onclicklistener动画无效

Question

我正在使用Android应用程序，当我点击按钮时，我的动画无效。

这是我的代码，

//Login layout signup button click listener to hide login layout and show signup layout
        loginUserSignupBTN.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
            startActivityActionFadeInAnim.setAnimationListener(new Animation.AnimationListener() {
                @Override
                public void onAnimationStart(Animation animation) {
                    signupDetailsLayout.startAnimation(startActivityActionSlideUpAnim);
                }

                @Override
                public void onAnimationEnd(Animation animation) {

                }

                @Override
                public void onAnimationRepeat(Animation animation) {

                }
            });

            startActivityActionFadeOutAnim.setAnimationListener(new Animation.AnimationListener() {
                @Override
                public void onAnimationStart(Animation animation) {
                    loginDetailsLayout.setAnimation(startActivityActionSlideDownAnim);
                }

                @Override
                public void onAnimationEnd(Animation animation) {
                    try {

                        Thread.sleep(200);

                    } catch (InterruptedException e) {
                        //We are doing nothing here
                        System.out.println(e.toString());
                    }
                    finally {
                        signupDetailsLayout.startAnimation(startActivityActionFadeInAnim);
                    }
                }

                @Override
                public void onAnimationRepeat (Animation animation){

                }
            });


            loginDetailsLayout.setAnimation(startActivityActionFadeOutAnim);

            Toast.makeText(StartActivity.this, "Signup clicked", Toast.LENGTH_LONG).show();
        }
    });

Toast工作正常，但我正在尝试的动画无效。

这是我的xml布局文件，

</RelativeLayout>

我也尝试过创建一个函数，但它也没有用，代码是

//Login layout signup button click listener to hide login layout and show signup layout
        loginUserSignupBTN.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                activateLayoutAnimation(signupDetailsLayout, loginDetailsLayout);
                //Toast.makeText(StartActivity.this, "Signup clicked", Toast.LENGTH_LONG).show();
            }
        });

和功能是，

//For action layout animations
    private void  activateLayoutAnimation(final RelativeLayout showLayout, final RelativeLayout hideLayout){


        startActivityActionFadeInAnim.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
                showLayout.startAnimation(startActivityActionSlideUpAnim);
            }

            @Override
            public void onAnimationEnd(Animation animation) {

            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });

        startActivityActionFadeOutAnim.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
                hideLayout.setAnimation(startActivityActionSlideDownAnim);
            }

            @Override
            public void onAnimationEnd(Animation animation) {
                try {

                    Thread.sleep(200);

                } catch (InterruptedException e) {
                    //We are doing nothing here
                    System.out.println(e.toString());
                }
                finally {
                    showLayout.startAnimation(startActivityActionFadeInAnim);
                }
            }

            @Override
            public void onAnimationRepeat (Animation animation){

            }
        });


        hideLayout.setAnimation(startActivityActionFadeOutAnim);


    }

setAnimation不会立即启动动画。要立即开始，请改为调用startAnimation。
