Question

我是Android开发的新手，现在我很难获得当前的用户位置。

清单：

HAS_PROFILE

MainActivity：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Logd返回int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION); Log.d("Check if permission", "permission is: " + permissionCheck);

我做错了什么呢？

使用Android Studio，target-sdk为23

Answer 1

checkSelfPermission()将检查用户是否已授予权限。如果检查失败（在您的情况下为-1），则需要使用requestPermissions()

的用户请求权限

对它的一个很好的解释，以及如何检查，通知和请求权限的示例，在android docs（http://developer.android.com/training/permissions/requesting.html#perm-request）中

如果链接死亡，这里是他们的代码：

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
                Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.READ_CONTACTS)) {

        // Show an expanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.

    } else {

        // No explanation needed, we can request the permission.

        ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.READ_CONTACTS},
                MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}
