上次的获取权限信息的Demo略显繁琐，优化了一下，使用系统接口PermissionInfo获取常见的权限描述，如果是对系统不可知的权限，我们在自定义。另外自定义的权限信息函数也从if else语句换成了swithc case语句，虽然还是一大堆，但是看起来结构更清晰一些：

package com.zms.getpermission;

import android.app.ListActivity;
import android.content.Intent;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageManager;

import android.content.pm.PermissionInfo;
import android.content.pm.ResolveInfo;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
