您收到的是一个

ClassCastException

这意味着，您使用的类型是错误的

searchView = (SearchView)findViewById(R.id.pointa);

你有两个选择：

1） 在该类文件的顶部查找

SearchView

的

import

语句，并将其从

android.widget.SearchView

更改为

android.support.v7.widget.SearchView

（或相反）

2） 仔细查看XML文件，查找

您的错误是您的解决方案java.lang.ClassCastException:android.widget.SearchView无法转换为android.support.v7.widget.SearchView您使用的是两个不同版本的SearchView。只需从日志中选择support.v7 one即可->
