很简单没什么说的， 因为项目大了，不能轻易引入第三方库，同时确实也没必要为了适配下权限就引入一个库。

这里写了个处理权限的工具类(部分借鉴的，勿喷)，不嫌弃的话拿去！

用法：

1.申请权限：

PermissionHelper mHelper = new PermissionHelper(this);

mHelper.requestPermissions("请授予xx[相机]，[读写]权限！",

new PermissionHelper.PermissionListener() {

@Override

public void doAfterGrand(String... permission) {

}

@Override

public void doAfterDenied(String... permission) {

}

}, Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE);

2.处理申请的结果：

//直接把参数交给mHelper就行了

@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

mHelper.handleRequestPermissionsResult(requestCode, permissions, grantResults);

}

代码如下:

import android.annotation.TargetApi;

import android.app.Activity;

import android.app.Fragment;

import android.content.Context;

import android.content.DialogInterface;

import android.content.pm.PackageManager;

import android.os.Build;

import android.support.annotation.NonNull;

import android.support.annotation.Nullable;

import android.support.v4.app.ActivityCompat;

import android.support.v4.content.ContextCompat;

import android.support.v7.app.AlertDialog;

import net.chuangdie.mcxd.R;

import java.util.Arrays;

import java.util.List;
