can somebody tell me how to set the size of the button that we make.
and also how to set its position.??
thx

Hi,u can set the position use a layout like LinearLayout,RelativeLayout...
You can use android:layout_width and android:layout_height to set the size in your xml like this:

<Button android:id="@+id/play_button"
android:layout_width="60dip"
android:layout_height="60dip"
android:padding="10px"
android:text="PLAY"
android:layout_alignParentLeft="true"/>

You can also set when you add your button through code by calling addView who take your component and a layout, the layout let you define size of components for example :
addView(myLabel, new AbsoluteLayout.LayoutParams(
10, LayoutParams.WRAP_CONTENT,0,0));

Here the first attribute are relative to the size.

I tried using this to centre the Button across the screen horizontally but it doesn't work. My XML snippet for the button is:

<Button
android:id="@+id/Button"
android:layout_height="wrap_content"
android:text="@string/buttonC"
android:layout_width="wrap_content"
android:layout_centerInParent="true" />

I've also tried using 'android:layout_centerHorizontal' and surrounding the Button XML in a <LinearLayout> tag as well.

Any help would be greatly appreciated. Thanks

Doh....I posted too quickly as I've now figured it out

Needed to put the button inside a RelativeLayout

You can also use the android:layout_x="XXpx" and android:layout_y="XXpx" tags within an AbsoluteLayout to specify exact placement.
