PermissionsDispatcher使用

首先添加依赖

compile 'com.github.hotchemi:permissionsdispatcher:4.6.0'
annotationProcessor 'com.github.hotchemi:permissionsdispatcher-processor:4.6.0'

注解列表

@RuntimePermissions注解：用于标注在需要申请权限的Activity或Fragment

@RuntimePermissions
class RememberToRemindActivity:SimpleActivity(){
}

@NeedsPermission注解：用于标注需要获取的权限，多个权限用逗号分隔，，权限申请成功后会调用被注解的方法使用如下

@NeedsPermission(Manifest.permission.RECORD_AUDIO,Manifest.permission.READ_PHONE_STATE,Manifest.permission.READ_CONTACTS,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.READ_CALENDAR,Manifest.permission.WRITE_CALENDAR)
    fun permissionsSuccess(){
       //这是权限申请成功后会调用的方法
    }

这两个注解后，需要build project，build完在onCreat中调用新生成的方法

permissionsSuccessWithPermissionCheck()//PermissionsDispatcher生成的辅助类

@OnShowRationale注解：这个方法用于告诉用户你接下来申请的权限是干嘛的，说服用户给你权限

@OnShowRationale(Manifest.permission.RECORD_AUDIO,Manifest.permission.READ_PHONE_STATE,Manifest.permission.READ_CONTACTS,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.READ_CALENDAR,Manifest.permission.WRITE_CALENDAR)
    fun berforpermissions(request:PermissionRequest){
        //此方法需要传入PermissionRequest对象，此对象有两个方法proceed()让权限请求继续，cancel()让请求中断。
    }

@OnPermissionDenied注解：用于标注如果权限请求失败，但是用户没有勾选不再询问的时候执行的方法

@OnPermissionDenied(
        Manifest.permission.RECORD_AUDIO,
        Manifest.permission.READ_PHONE_STATE,
        Manifest.permission.READ_CONTACTS,
        Manifest.permission.WRITE_EXTERNAL_STORAGE,
        Manifest.permission.ACCESS_FINE_LOCATION,
        Manifest.permission.READ_CALENDAR,
        Manifest.permission.WRITE_CALENDAR
    )
    fun permissionsDenied() {
        permissionsSuccessWithPermissionCheck()//此处调用上面的辅助类，重新申请权限
    }

实现这个方法还需要实现回调方法

override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array,
        grantResults: IntArray
    ) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        onRequestPermissionsResult(requestCode, grantResults)
    }

@OnNeverAskAgain注解：用于标注如果权限请求失败,而且用户勾选不再询问的时候执行的方法

@OnNeverAskAgain(
        Manifest.permission.RECORD_AUDIO,
        Manifest.permission.READ_PHONE_STATE,
        Manifest.permission.READ_CONTACTS,
        Manifest.permission.WRITE_EXTERNAL_STORAGE,
        Manifest.permission.ACCESS_FINE_LOCATION,
        Manifest.permission.READ_CALENDAR,
        Manifest.permission.WRITE_CALENDAR
    )
    fun permissionsNeverAskAgain() {
        //自己需要的方法
    }

以上注解，除了第一个和第二个是必须要的注解，其他的都是非必要的注解。
