在使用过程中可能会遇到的问题总结:
问题1: 在fragment中使用时无法隐藏和点击问题
缘由: 前几天发现了一个控件显示问题, 最近任务被安排的很满, 一直没时间去改, 直到昨天, 这个任务分给了我, 我昨天任务太多, 所有今天才处理这个问题.
问题描述: 我们的项目里使用了一个开源控件, 该控件博客介绍地址(https://www.jb51.net/article/91158.htm), 这个控件展开没有任何问题, 但是隐藏时会出现问题, 是这样的, 我们在fragment中使用该控件时, 当该控件隐藏后, 来回切换fragment时发现, 该控件显示了出来, 并且item是无法点击的.
解决方案: 我看了源码后发现, 可能是作者的疏忽了, 忘记了一行代码, 就是在执行完隐藏动画后, 设置了animationSet.setFillAfter(true)属性, 让view保持动画结束的状态, 当我们切换fragment的时候, view重新绘制了, 这是这个属性就不起做作用了, 导致所有的item显示了, 并且无法点击是因为作者添加了childView.setClickable(false)这行代码, 禁止掉了view的点击事件, 到这里问题已经可以解决了, 这里只需要加上childView.setVisibility(View.GONE)这行代码即可;
可能有人不知道在哪里加这行代码, 我把整个方法贴出来, 后面还会把这个类以及这个类的使用和布局xml都会贴出来供大家学习借鉴:
/**
* Item的点击隐藏动画
*/
private void menuItemAnim(int pos) {
for (int i = 0; i < getChildCount() - 1; i++) {
View childView = getChildAt(i + 1);
if (i == pos) {
childView.startAnimation(scaleBigAnim(300));
} else {
childView.startAnimation(scaleSmallAnim(300));
}
//item不可点击
childView.setClickable(false);
childView.setFocusable(false);
//解决无法显示并且无法点击问题
childView.setVisibility(View.GONE);
}
}
