Android 浮动拖拽和关闭按钮记录

以前调试浮动推拽时，点击跳转那块的UI 无法触发推拽，原因是给那块设置了点击事件。需要给整个Ui设置点击事件才不会抢到推拽的焦点。记录代码如下：

package com.base.chat.test.debug;

import android.content.res.Configuration;
import android.view.MotionEvent;
import android.view.View;
import android.view.animation.DecelerateInterpolator;

import com.blankj.utilcode.util.TouchUtils;
import com.base.chat.R;
import com.base.chat.test.TestActivity;
