问题

CheckBox设置isCheck=true，会自动触发监听事件onCheckedChanged，从而导致里面方法会自动执行?

---

解决方法

可用把全选、全不选的CheckBox通过点击事件来实现选择

/**
* 全选  全不选 部分代码
*/
var isAllChecked = false;//ture：全选   false:全不选

cbAll.setOnClickListener(this)
override fun onClick(v:View?){
    when(v?.id){
        R.id.cbAll ->{//全选  全不选
              isAllChecked = !isAllChecked
                if (isAllChecked) {//全选
                    cbReceivables.isChecked = true
                    cbActivity.isChecked = true
                    cbCash.isChecked = true
                    cbMemManagment.isChecked = true
                    cbDistribution.isChecked = true
                    cbStoreOper.isChecked = true
                } else {//全不选
                    cbReceivables.isChecked = false
                    cbActivity.isChecked = false
                    cbCash.isChecked = false
                    cbMemManagment.isChecked = false
                    cbDistribution.isChecked = false
                    cbStoreOper.isChecked = false
                }
        }
  }
}


 /**
   * 单选的操作
  */
  cbActivity.setOnCheckedChangeListener(this)
  cbCash.setOnCheckedChangeListener(this)
  cbMemManagment.setOnCheckedChangeListener(this)
  cbDistribution.setOnCheckedChangeListener(this)
  cbStoreOper.setOnCheckedChangeListener(this)

 override fun onCheckedChanged(buttonView: CompoundButton?, isChecked: Boolean) {
        isAllCheck(isChecked)
    }

 /**
   * 判断是否全选
   */
    fun isAllCheck(isChecked: Boolean) {
        if (isChecked) {
            if (cbReceivables.isChecked && cbActivity.isChecked && cbCash.isChecked
                && cbMemManagment.isChecked && cbDistribution.isChecked && cbStoreOper.isChecked
            ) {
                cbAll.isChecked = true
                isAllChecked = true
            }
        } else {
            cbAll.isChecked = false
            isAllChecked = false
        }
    }
