Problem with borders when resizing the height of EditText

Question

I'm developing an Android app targeting Android 2.3 (API9).

I want to resize the height of a simple EditText but when I set android:layout_height="10pt" the border of the EditText becomes dislocated.

The problem is shown here

enter image description here

I tried layout_height, height, textsize.. pt, px, sp... but the same problem.

I haven't tried the application on real device yet.

What layout contains the EdiText? You should never use exact pixel sizes when configuring items in Android, since your layout needs to work properly at many different screen sizes and densities. (See supporting multiple screens for details).

If you really want a specific size, us dp for density independent pixels. It should work to set the layout_height="10dp" However, that won't increase the size of the text within the EditText. You need to use textSize for that. You are probably better off setting textSize and setting the layout_height="wrap_content".

See this similar question about the extra line. It looks like setting a background color might fix that.

I have this xml: but the same problem with the border. I tried layout_height: wrap_content .. but this does not change the height of the EditBox. Stanislav – Stancho Feb 01 '11 at 22:10
Did you set the background color as suggested? – Cheryl Simon Feb 01 '11 at 22:38
Also, a text size of 3dp is very small. If you set it higher, you should see the size of the EditText increase. – Cheryl Simon Feb 01 '11 at 22:38
Mayra thanks for your quick reply! If I set the bg of the EditText =WHITE.. I don't see any borders – Stancho Feb 01 '11 at 22:53
How can I set the borders this way? – Stancho Feb 01 '11 at 22:54
I think you might need to use a custom background using the 9 patch tool, which allows for a background image that stretches: http://developer.android.com/guide/developing/tools/draw9patch.html – Cheryl Simon Feb 02 '11 at 00:27
Mayra, 10x. It's ok if I user custom background IMAGE. – Stancho Feb 02 '11 at 08:37

I have been having the same sort of problem (and it's a real pain). With some experimentation I have found that if you use "dp" and apply this rule of thumb, it should work for EditText fields.

textSize x 3= layout_height

I say rule of thumb because the minimum height before the field "breaks" again is about 29dp. So, for example if you have textSize="10dp", then layout_height="30dp", or textSize="12dp", then layout_height="36dp". You can have smaller textSizes, but it becomes illegible lower than 9dp. I found this works well in relative_layouts with default fonts. Good luck!
