To create a custom toast message that shows an image and some text use this java code.

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.toast_layout, (ViewGroup) findViewById(R.id.toast_layout_root));

TextView text = (TextView) layout.findViewById(R.id.text);

text.setText(content);
image.setImageBitmap(bmImg);

ImageView image = (ImageView) layout.findViewById(R.id.image);
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();

and this layout file

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/toast_layout_root"
          android:orientation="horizontal"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:padding="10dp"
          android:background="#DAAA"
          >
<ImageView android:id="@+id/image"
           android:layout_width="40dp"
           android:layout_height="40dp"
           android:layout_marginRight="10dp"
           />
<TextView android:id="@+id/text"
          android:layout_width="wrap_content"
          android:layout_height="fill_parent"
          android:textColor="#FFF"
          />
</LinearLayout>

This project demonstrates adding popup panels (ones that persist, unlike a Toast) over top of a map.
