# XPermissionUtils

可能是最精简的Android6.0运行时权限处理方式

流程图

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(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
          deniedPermissions代表被拒绝的权限
          alwaysDenied代表是否永远被拒绝
• 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) {
                            requestPermissions(deniedPermissions, RequestCode.CAMERA);
                        }
                    })
                    .show();
            }
        }
    });
}
