本文介绍了一个针对 Android M (API 23) 的权限请求封装类，用于简化应用程序在运行时请求权限的过程。通过定义 BaseActivity 和 PermissionCallback 接口，实现了权限请求的统一管理和回调，包括权限检查、请求、再次请求时的用户提示以及权限请求结果的处理。

BaseActivity.java

package com.gaozewen.smssender;

import android.content.DialogInterface;
import android.content.pm.PackageManager;
import android.os.Build;
import android.support.annotation.NonNull;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.widget.Toast;


public class BaseActivity extends AppCompatActivity {
    //**************** Android M Permission (Android 6.0权限控制代码封装)
    private int permissionRequestCode = 88;
    private PermissionCallback permissionRunnable;

    public interface PermissionCallback {
        void hasPermission();

        void noPermission();
    }

    /**
     * Android M运行时权限请求封装
     *
     * @param permissionDes 权限描述
     * @param runnable      请求权限回调
     * @param permissions   请求的权限（数组类型），直接从Manifest中读取相应的值，比如Manifest.permission.WRITE_CONTACTS
     */
    public void performCodeWithPermission(@NonNull String permissionDes, PermissionCallback runnable, @NonNull String... permissions) {
        if (permissions.length == 0)
            return;
        // this.permissionrequestCode = requestCode;
        this.permissionRunnable = runnable;
        // Build.VERSION.SDK_INT 来自 build.gradle.
        if ((Build.VERSION.SDK_INT < Build.VERSION_CODES.M) || checkPermissionGranted(permissions)) {
            if (permissionRunnable != null) {
                permissionRunnable.hasPermission();
                permissionRunnable = null;
            }
        } else {
            //permission has not been granted.

        }

    }

        if (shouldShowRequestPermissionRationale(permissions)) {
            /*1. 第一次请求权限时，用户拒绝了，下一次：shouldShowRequestPermissionRationale()  返回 true，应该显示一些为什么需要这个权限的说明
            2.第二次请求权限时，用户拒绝了，并选择了“不在提醒”的选项时：shouldShowRequestPermissionRationale()  返回 false
            3. 设备的策略禁止当前应用获取这个权限的授权：shouldShowRequestPermissionRationale()  返回 false*/
            // Provide an additional rationale to the user if the permission was not granted
            // and the user would benefit from additional context for the use of the permission.
