android6.0权限通用管理(不在头大)

一个类解决Android6.0权限的繁杂，完美应付日常开发，欢迎指教~

在activity中涉及到需要申请权限的功能时,比如点击按钮照相,这是主要一段代码，没什么难度就是做了一个统一回调:

  /***
         * request permission for activity's method of up 6.0
         * @param permissions
         * @param listener
         */
        public void requestPermissionFeature(String[] permissions, PermissionListener listener) {
            if (activity == null)
                return;
            shouldRequestPermissions = new ArrayList<>();
            denied = new ArrayList<>();
            tips = new ArrayList<>();
            this.permissionListener = listener;
            if (isNeedRequestPermission()) {
                for (int i = 0; i < permissions.length; i++) {
                    if (ContextCompat.checkSelfPermission(activity, permissions[i]) != PackageManager.PERMISSION_GRANTED)
                        shouldRequestPermissions.add(permissions[i]);
                }
                if (shouldRequestPermissions.size() > 0) {
                    String[] requestPermissions = shouldRequestPermissions.toArray(new String[shouldRequestPermissions.size()]);
                    ActivityCompat.requestPermissions(activity, requestPermissions, PERMISSIONS_REQUEST_CODE);
                } else {
                    if (permissionListener != null)
                        permissionListener.granted();

                }

            } else {
                if (permissionListener != null)
                    permissionListener.granted();
            }
        }

在activity中这样用,同意回调，拒绝回调，拒绝后不再提示回调(需要用户手动去设置开启)，注意:如果这个功能需要多个权限，有一个用户没有通过，那么该功能不可用，大家根据自己的需求在不同的回调里做操作:

    private void permissget() {   
        builder.activity(this).requestPermissionFeature(new String[]{Manifest.permission.READ_PHONE_STATE}, new Permission.PermissionListener() {
            @Override
            public void granted() {
                initInfo();
            }
            @Override
            public void deniedNeverAsk() {
                ToastUtils.showToast(WelcomeActivity.this,getString(R.string.deniedNeverAsk));
            }
            @Override
            public void denied() {
                finish();
            }
        });
    }
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        builder.RequestPermissionsResult(requestCode,permissions,grantResults);
    }

在fragment中差不多的用法把上面的builder.activity(this)换成builder.fragment (this), 方法名requestPermissionForFragment，我会把全部类贴出来直接拿去用就ok了！！！

如果有什么问题还请指出。。后面会有更多野路子来应付实际开发(都是坑啊)
