SupportMapFragment with a custom layout, possible?

问题

I am trying to have SupportMapFragment with a custom layout, right now the following code works :

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        View view = super.onCreateView(inflater, container, savedInstanceState);
        // initMap();
        return view;
    }

But I want to change the onCreateView() method to inflate a different layout, instead of calling the super.onCreateView() method. To look like something like this:

View view  = inflater.inflate(R.layout.fragment, container,false);
mMap = (GoogleMap)view.findViewById(R.id.mapview);

But GoogleMap is not a view so I cannot add it to the xml, like the following way:

<com.google.android.gms.maps.GoogleMap
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

回答1:

If you want to create a SupportMapFragment with a custom layout, I prefer to extend the android.support.v4.app.Fragment from the Support Library and inflate your custom XML with the com.google.android.gms.maps.MapView and other views there.

But be careful to forward the livecycle methods to this MapView as quoted here.

I added a LinearLayout above the map. I used this layout for the buttons:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/llPlaces"
android:orientation="horizontal"
android:background="@color/ACGris">
    <Button android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="BUTTON1"/>
    <Button android:id="@+id/btn2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="BUTTON2"/>
    <Button android:id="@+id/btn3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="BUTTON3"/>

And then I created a class which extends SupportMapFragment

public class FrgMapas extends SupportMapFragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View viewMain = super.onCreateView(inflater, container, savedInstanceState);
    View viewButtons = inflater.inflate(R.layout.layout_buttons, null);

    FrameLayout mainChild = (FrameLayout) ((ViewGroup)viewMain).getChildAt(0);
    mainChild.addView(viewButtons);

    Button btn1 = (Button) viewMain.findViewById(R.id.btn1);
    btn1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(getActivity(), "TuTa :)", Toast.LENGTH_LONG).show();
        }
    });

    return viewMain;
}

Hope this works for you

com.google.android.gms.maps.MapView is a View that you can embed in your layouts.

回答4:

You can override onCreateView in the class you derive from SupportMapFragment. You can call super.onCreateView and then insert the result into a custom ViewGroup you inflater or instantiate. Here's some sample code

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    FrameLayout layout = (FrameLayout) inflater.inflate(R.layout.my_layout,
            container, false);

    View v = super.onCreateView(inflater, container, savedInstanceState);
    layout.addView(v, 0);
    return layout;
}
