Google Maps Android API v2中会忽略我的自定义InfoWindow布局的宽度

Question

The width I set in my custom InfoWindow layout seems to be ignored (it always match_parent).

Am I missing something?

mMap.setInfoWindowAdapter(new InfoWindowAdapter() {

    @Override
    public View getInfoWindow(Marker arg0) {
        return null;
    }

    @Override
    public View getInfoContents(Marker arg0) {

        View v = getActivity().getLayoutInflater().inflate(R.layout.info_window_layout, null);

        // set my custom data

        return v;

    }
});

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="100dp"
    android:layout_height="50dp"
    android:padding="5dp" >

    <!-- some custom stuff -->

</RelativeLayout>

Answer 1

I suppose it would actually be wrap_content.

The way info window works is by drawing your View to a bitmap and not putting it inside any other ViewGroup. layout_xxx are used by parent View.

Hardcoding these values on some or all children of your RelativeLayout will probably solve your problem.

try to use this in getInfoWindow, getInfoContents return null:

<LinearLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:background="@drawable/transparent">

        <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center_horizontal"
                android:orientation="vertical">

            <!-- some custom stuff -->

        </LinearLayout>
    </LinearLayout>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="#8BC34A"
android:orientation="vertical"
android:paddingBottom="@dimen/small_padding"
android:paddingLeft="@dimen/very_samll_padding"
android:paddingRight="@dimen/very_samll_padding"
android:paddingTop="@dimen/small_padding">


<LinearLayout
    android:layout_width="320dp"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv_address"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@color/white" />

    <LinearLayout
        android:id="@+id/ll_latlong"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv_address"
        android:layout_marginTop="@dimen/very_samll_padding"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/tv_lat"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:textColor="@color/white" />

        <View
            android:layout_width="1dp"
            android:layout_height="12dp"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="@dimen/small_padding"
            android:layout_marginRight="@dimen/small_padding"
            android:background="@color/white" />

        <TextView
            android:id="@+id/tv_long"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:textColor="@color/white" />
