Question

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始终返回0（== PackageManager.PERMISSION_GRANTED）

我设法将其从ContextCompat更改为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 build中的依赖关系

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
}

您的许可应为Manifest.permission.<Android permission> 你的Android目标版本是什么？ shouldShowRequestPermissionRationale总是返回false，表示ContextCompat.checkSelfPermission(activity, permission)总是在23岁以下的Android API lvl中返回false。

Document here。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，则该方法也会返回false。

ContextCompat.checkSelfPermission（Context，Manifest.permission.CAMERA）总是返回授予
