How to make custom tool-tip/pop-up
===

I'm working on kind of tool-tip which I suppose has to be a custom pop-up.
The tool-tip is an image, appears ones when application is started. The image has to be shown on specific location and closed when user touches a screen and never shown again.

I've started with style.xml file in res/values

    <?xml version="1.0" encoding="utf-8"?>
    <resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="CustomDialotTheme" parent="@android:style/Theme.Dialog">
    <item name="android:windowBackground">@drawable/hint</item>    
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowNoTitle">true</item>
    </style>
    </resources>

in .java:

    Dialog _hintDialog = new Dialog(this, R.style.CustomDialotTheme);
    _hintDialog.setContentView(R.layout.shops_view);
    _hintDialog.setCancelable(false);
    _hintDialog.show();

It never shows up.
Maybe there is another way to create a tool-tip or appreciate any suggestion how to create a custom pop-up I need.
