我在我的应用程序中使用 Android API lvl 23。当我检查相机权限时，ContextCompat.checkSelfPermission总是返回 0 ( == PackageManager.PERMISSION_GRANTED)

我设法将其从 更改ContextCompat为ActivityCompat。

这是我的代码：

public static boolean verify(Activity activity, final String[] PERMISSIONS, final int PERMISSIONS_REQUEST_ID) {
    if (underAPI23())
        return true;

    String[] denyPermission = new String[PERMISSIONS.length];
    int denyPermissionLength = 0;
    boolean shouldShowRequest = false;

    for (int i = 0; i < PERMISSIONS.length; i++) {
        int check = ContextCompat.checkSelfPermission(activity, PERMISSIONS[i]);
        LogUtils.e(TAG, PERMISSIONS[i] + ": " + (check != PackageManager.PERMISSION_GRANTED));
        // ===== ===== =====
        // This always return true. :'(
        // ===== ===== =====
        if (check != PackageManager.PERMISSION_GRANTED) {
            denyPermission[denyPermissionLength++] = PERMISSIONS[i];
            if (shouldShowRequest == false) {
                boolean should = ActivityCompat.shouldShowRequestPermissionRationale(activity, PERMISSIONS[i]);
                if (should)
                    shouldShowRequest = true;
            }
        }
    }

    if (denyPermissionLength > 0) {
        if (shouldShowRequest) {
            ActivityCompat.requestPermissions(activity, denyPermission, PERMISSIONS_REQUEST_ID);
        } else {
            ActivityCompat.requestPermissions(activity, denyPermission, PERMISSIONS_REQUEST_ID);
        }
        return false;
    } else {
        return true;
    }
}

我在 Gradle 构建中的依赖项

dependencies {
    //...
    compile 'com.android.support:support-v4:23.2.0'
    compile 'com.android.support:appcompat-v7:23.2.0'
    //...
}

更新：权限调用

if (PermissionGrant.verify(getActivity(), new String[]{Manifest.permission.CAMERA}, GRANT_TAKE_PHOTO)) {
    // Do my jobs
}

您的权限应该Manifest.permission.<Android permission> 是您的 Android 目标版本是什么？shouldShowRequestPermissionRationale总是返回false这意味着ContextCompat.checkSelfPermission(activity, permission)总是在 23 岁以下的 Android API lvl 上返回 false。

文件在这里。请关注：

注意：如果用户过去拒绝了权限请求并在权限请求系统对话框中选择了不再询问选项，则此方法返回 false。如果设备策略禁止应用程序拥有该权限，该方法也会返回 false。
