Hello rahul,

For placing Views over another View have a look here: viewtopic.php?p=4590#4590

For drawing things on the top of a MapView have a look on the FriendFinder-Tutorial and here.

Hey +/- thanks for this one
So you mean that we do can add normal text/edittext views etc over the canvas too
I really like the first one and have seen this earlier but guess you are sending this to
challenge itself as an entry

Just was curious how we can add normal text/edit text view over the current canvas
Share the snippits if not the actual code

How you made the rectangle at the bottom transparent

Hello Rahul,

You can place any View over any other View.
The code is just the same as the one after my previous link, except you need to change the class from ImageView to TextView/EditText.

Simply call [font=Lucida Console]myPaint.setAlpha(int alphaValue);[/font] on the Paint you are drawing the rectangle to the canvas.

But again I dont see anywhere where I can draw a textview/editview on canvas
I mean on canvas you can draw text but again you just cant editView on canvas

Also can you share your code a bit where you created a ImageView from a image
and draw on canvas
I see that you have decoded the image as bitmap and then on canvas you are drawing
the bitmap

Sorry if I didnt catch what you mean
Please help

Hello rahul,

you do not draw a EditText over a Map, but you define it in xml to be above, just like this:

This code ...

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent">
     <view class="com.google.android.maps.MapView"
          android:id="@+id/map_map"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"/>
     <ImageView
          android:id="@+id/iv_map_zoomin"
          android:layout_alignParentTop="true"
          android:layout_alignParentRight="true"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:src="@drawable/plus_32"/>
     <ImageView
          android:id="@+id/iv_map_zoomout"
          android:layout_alignParentTop="true"
          android:layout_alignParentLeft="true"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:src="@drawable/minus_32"/>
</RelativeLayout>
Parsed in 0.003 seconds,  using GeSHi 1.0.8.4

... produces this output (two clickable (Image)Views, being automatically drawn above of the map(and potentional map-overlays)):
See the upper corners of the mapView.

I tried the same but didnt get anything
Then I switched my layout to relativelayout
and everything was right there
Wonder why things in Linear Layout didnt work

But guess that gives me a head on

I really appreciate your kind help

Thanks
Rahul
