我是新来的。所以首先。谢谢你的帮助。
我把这个片段称为buscar_cancha：

我把它叫做替换另一个片段。父片段是：
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawerlayout">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/fragmentholder">
</FrameLayout>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/navlist"
android:background="#dedede"
android:layout_gravity="start"
>
</ListView>
</android.support.v4.widget.DrawerLayout>
我的代码需要一些帮助。我不知道，但我无法在AsyncTask上获得我的位置。
@Override
protected Location doInBackground(Void... params) {
//mMap.setMyLocationEnabled(true);
loc = mMap.getMyLocation();
return loc;
}
我知道我无法在doInbackground更改我的用户界面，因此我在doInBackground中尝试了该操作系统并在onPostExecute上修改了我的用户界面。
@Override
protected void onPostExecute(Location loc) {
super.onPostExecute(loc);
if (loc != null) {
LatLng latLang = new LatLng(loc.getLatitude(), loc
.getLongitude());
mMap.addMarker(new MarkerOptions().position(latLang).title("Here I am"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLang));
mMap.animateCamera(CameraUpdateFactory.zoomTo(13));
}
else{
Toast my= Toast.makeText(getContext(), "Still doenst work",Toast.LENGTH_SHORT);
my.show();
}
但我得到了这个

当我将函数getMyLocation放在onPostExecute()方法上时。有用。但只有当我将电源设备底部按下两次时。我决定使用Asynctask因为我用OnReadyMap尝试了它并且它不起作用。所以我认为问题出在咨询时。我需要某种解决方案或提示。谢谢
