当我Activity
调用ActivityCompat.requestPermissions
时,不显示用户界面对话框。
ActivityCompat.requestPermissions(HomeActivity.this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
我在手机上有这个屏幕:
我不知道该怎么做,我试着用:
requestPermissions( new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
我有相同的结果,如果我将该行放在注释中并且我没有出现的窗口但我没有结果(UI对话框)
答案 0 :(得分:0)
试试这个:
ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
还要确保在清单中有这个:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
获取许可结果:
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) {
} 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
}
}
