Question

我有一个需要淡入的按钮。但它只是第一次工作。它第二次没有工作。

这是我的代码。

    final TextView doctorInfoView = (TextView) rowView.findViewById(R.id.doctorInfo);
    final TextView specialtyView = (TextView) rowView.findViewById(R.id.specialty);

    final ImageButton deleteDoctor = (ImageButton)rowView.findViewById(R.id.deleteDoctor);
    final Animation fadeInAnimation = AnimationUtils.loadAnimation(context, R.anim.fade_in_animate);
    final ImageButton editDoctor = (ImageButton)rowView.findViewById(R.id.editDoctor);
    final RelativeLayout mainRowLayout = (RelativeLayout)rowView.findViewById(R.id.doctorListInfoView);
    final LinearLayout rowLayout = (LinearLayout)rowView.findViewById(R.id.doctorInfoLayout);
    final LinearLayout editButtonLayout = (LinearLayout)rowView.findViewById(R.id.editButtonLayout);
    final LinearLayout deleteButtonLayout = (LinearLayout)rowView.findViewById(R.id.deleteButtonLayout);
    rowLayout.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            if (isClicked) {
                editDoctor.setAnimation(fadeInAnimation);
                editDoctor.setVisibility(View.VISIBLE);
                deleteDoctor.setAnimation(fadeInAnimation);
                deleteDoctor.setVisibility(View.VISIBLE);
                mainRowLayout.setBackgroundColor(Color.parseColor("#ffffff"));
                doctorInfoView.setTextColor(Color.parseColor("#eeeeee"));
                specialtyView.setTextColor(Color.parseColor("#eeeeee"));
                editButtonLayout.setBackgroundColor(Color.parseColor("#16aea3"));
                deleteButtonLayout.setBackgroundColor(Color.parseColor("#16aea3"));
                isClicked = false;
            } else {
                editDoctor.setVisibility(View.GONE);
                deleteDoctor.setVisibility(View.GONE);
                                                                mainRowLayout.setBackgroundColor(Color.parseColor("#f2f2f4"));
                doctorInfoView.setTextColor(Color.parseColor("#000000"));
                specialtyView.setTextColor(Color.parseColor("#0d9e9f"));
                editButtonLayout.setBackgroundColor(Color.parseColor("#f2f2f4"));
                deleteButtonLayout.setBackgroundColor(Color.parseColor("#f2f2f4"));
                isClicked = true;
            }
        }

    });

这是fade_in_animate.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">
     <alpha 
           android:fromAlpha="0.0"
            android:toAlpha="1.0" 
            android:interpolator="@android:anim/accelerate_interpolator" 
            android:duration="500"/>
    </set>

我对任何反馈表示赞赏。

解决此问题的一种方法是将动画设置为null

editDoctor.setVisibility(View.GONE);
editDoctor.setAnimation(null);

编辑：你忘了将它设置为无限

animation.setRepeatCount(Animation.INFINITE);

这是xml

android:repeatCount="-1"
android:repeatMode="repeat"

以下是完整的documentation

编辑2：我没有看到你正在设置alpha。我的错。这应该工作！你不需要重复它。这适用于将动画设置为null的方法。

editDoctor.setVisibility(View.GONE);
editDoctor.setAnimation(null);
editDoctor.setAlpha(.0f);

android - 动画第二次没有工作
