To implement dynamic icon, modify layout of the info windows(custom_info_contents.xml) - remove the assigned android:src and assigne android:id="@+id/icon".
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:adjustViewBounds="true"/>
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12dp"
android:textStyle="bold"/>
<TextView
android:id="@+id/snippet"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10dp"/>
</LinearLayout>
</LinearLayout>
Modify getInfoContents(Marker marker) to load the icon in run-time.
@Override
public View getInfoContents(Marker marker) {
TextView tvTitle = ((TextView)myContentsView.findViewById(R.id.title));
tvTitle.setText(marker.getTitle());
TextView tvSnippet = ((TextView)myContentsView.findViewById(R.id.snippet));
tvSnippet.setText(marker.getSnippet());
ImageView ivIcon = ((ImageView)myContentsView.findViewById(R.id.icon));
ivIcon.setImageDrawable(getResources().getDrawable(android.R.drawable.ic_menu_gallery));
return myContentsView;
}
