我的 list 中有以下内容:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
我还在手机设置中设置了位置权限。
是的，手机上启用了 GPS。
在这里，我检查权限:
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
int hasLocationPermission = mContext.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION);
Log.d(TAG, "location permission: " + hasLocationPermission); // 0
if (hasLocationPermission != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(mContext, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
}
hasLocationPermission = mContext.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION);
Log.d(TAG, "location permission: " + hasLocationPermission); // still 0
}
如果我在我的 list 和手机的应用程序设置中获得许可，为什么它仍然阻止我访问该位置？因此，纬度和经度都返回 0.0。
最佳答案
声明你在哪里使用 Oncreate 或其他
if (Build.VERSION.SDK_INT >= 23){
if (checkPermission(Manifest.permission.ACCESS_FINE_LOCATION,getApplicationContext(),this)) {
//You fetch the Location here
//code to use the
}
else
{
requestPermission(Manifest.permission.ACCESS_FINE_LOCATION,PERMISSION_REQUEST_CODE_LOCATION,getApplicationContext(),this);
}
}
也在类里面声明
public static void requestPermission(String strPermission,int perCode,Context _c,Activity _a){
if (ActivityCompat.shouldShowRequestPermissionRationale(_a,strPermission)){
Toast.makeText(getApplicationContext(),"GPS permission allows us to access location data. Please allow in App Settings for additional functionality.",Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(_a,new String[]{strPermission},perCode);
}
}
public static boolean checkPermission(String strPermission,Context _c,Activity _a){
int result = ContextCompat.checkSelfPermission(_c, strPermission);
if (result == PackageManager.PERMISSION_GRANTED){
return true;
} else {
return false;
}
}
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
switch (requestCode) {
case PERMISSION_REQUEST_CODE_LOCATION:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
fetchLocationData();
} else {
Toast.makeText(getApplicationContext(),"Permission Denied, You cannot access location data.",Toast.LENGTH_LONG).show();
}
break;
}
}
对于其他较低的设备，您应该在声明时给予许可
