本文介绍了代码中无法识别 MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION 权限 android的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我们目前正在尝试从 Android 手机请求 GPS 权限,以便我们可以在 Google 地图上显示当前位置.我们已将此清单包含在应用程序标签之外的清单标签下:
We are currently trying to request GPS permissions from an android phone so that we can show the current location on a Google Map. We have included this manifest, outside of application tags, under the manifest tag:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
这是我们代码中无法正常工作的部分,它无法识别 MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION:
Here is the part of our code that is not working, it is not recognising MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION:
if (ActivityCompat.checkSelfPermission(this,
android.Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
android.Manifest.permission.ACCESS_FINE_LOCATION)) {
// Show an explanation 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(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
我们还包含了导入 android.Manifest".
We have also included "import android.Manifest".
提前致谢!
推荐答案
你必须像这样定义:
public static int MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION =1;
然后将结果捕获为:
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION : {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the
// contacts-related task you need to do.
} else {
// permission denied, boo! Disable the
// functionality that depends on this permission.
}
return;
}
// other 'case' lines to check for other
// permissions this app might request
}
}
