# XPermissionUtils

可能是最精简的Android6.0运行时权限处理方式，支持Rationale提示，只有一个类，100行代码，所有弹窗等操作由用户自行处理，在Demo中也有提供代码示例

流程图

引入方式

1、gradle引入

dependencies {
    compile 'com.andsync.xpermission:XPermissionUtils:1.3'
}

2、Maven引入

<dependency>
  <groupId>com.andsync.xpermission</groupId>
  <artifactId>XPermissionUtils</artifactId>
  <version>1.3</version>
  <type>pom</type>
</dependency>

使用方式

以打开相机为例

1、首先AndroidManifest中配置必要的权限

<uses-permission android:name="android.permission.CAMERA"/>

2、在基类中加上回调方法

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
        @NonNull int[] grantResults) {
        XPermissionUtils.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

3、调用工具类方法

注意

• requestPermissions第一个参数必须为activity
• XPermissionUtils.OnPermissionListener监听中有两个回调方法
      onPermissionGranted()授权成功后的回调
      onPermissionDenied(final String[] deniedPermissions, boolean alwaysDenied)授权失败后的回调
      其中deniedPermissions标识被拒绝的权限alwaysDenied标识是否永远被拒绝
• 申请权限由String数组决定，如new String[] {Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO}

private void doOpenCamera() {
        XPermissionUtils.requestPermissions(this, RequestCode.CAMERA, new String[] { Manifest.permission.CAMERA },
            new XPermissionUtils.OnPermissionListener() {
                @Override
                public void onPermissionGranted() {
                    if (PermissionHelper.isCameraEnable()) {
                        Toast.makeText(MainActivity.this, "打开相机操作", Toast.LENGTH_LONG).show();
                    } else {
                        DialogUtil.showPermissionManagerDialog(MainActivity.this, "相机");
                    }
                }

                @Override
                public void onPermissionDenied(final String[] deniedPermissions, boolean alwaysDenied) {
                    Toast.makeText(context, "获取相机权限失败", Toast.LENGTH_SHORT).show();
                    if (alwaysDenied) { // 拒绝后不再询问 -> 提示跳转到设置
                        DialogUtil.showPermissionManagerDialog(MainActivity.this, "相机");
                    } else {    // 拒绝 -> 提示此公告的意义，并可再次尝试获取权限
                        new AlertDialog.Builder(context).setTitle("温馨提示")
                            .setMessage("我们需要相机权限才能正常使用该功能")
                            .setNegativeButton("取消", null)
                            .setPositiveButton("验证权限", new DialogInterface.OnClickListener() {
                                @RequiresApi(api = Build.VERSION_CODES.M)
                                @Override
                                public void onClick(DialogInterface dialog, int which) {
                                    XPermissionUtils.requestPermissionsAgain(context, deniedPermissions,
                                        RequestCode.CAMERA);
                                }
                            })
                            .show();
                    }
                }
            });
    }
