Cannot set Font size as TextView's height

Question

In my app I set one TextView and I noticed that there were some spaces above and below the text, as in the image below.

But my expected result is this :-

I Googled lots and found this answer link, but nothing happens.

Updated :

<TextView android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textSize="50dp"
              android:background="#484848"
              android:textColor="#fff"
              android:text="A"
              android:layout_centerInParent="true"/>

This is the tag I used for displaying text.

Updated :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/rl"
    tools:context=".MainActivity" >


    <TextView android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textSize="50dp"
              android:background="#484848"
              android:textColor="#fff"
              android:text="A"
              android:paddingTop="0dp"
              android:layout_centerInParent="true"/>


</RelativeLayout>

Hey add your TextView tag code i.e., xml layout code. it is hard to say what mistake you are doing without checking code. — TNR, Jan 18 '13 at 10:49
No other views only one textview. I gave you my whole layout code. — , Jan 18 '13 at 11:14

Actually, its a padding of 9-patch backgrounds drawable which is by default for Android TextView background. And you are just set color to it #484848. So you don't have any solution for it.

As per my concern use the same size of height (android:layout_height) for your TextView as same as your TextSize (android:textSize="50dip") of your TextView. (instead of android:layout_height="wrap_content")

Try with below code:

<TextView android:layout_width="wrap_content"
              android:layout_height="50dip"
              android:layout_marginTop="-5dip"
              android:textSize="50dip"
              android:background="#484848"
              android:textColor="#fff"
              android:text="A"
              android:includeFontPadding="false"
              android:layout_centerInParent="true"/>

I also added some margin in negative. android:layout_marginTop="-5dip"

Hope this will help you a little bit.

see my result picture and please let me know that can we make it perfect ?? — , Jan 18 '13 at 13:33
@xDeveloper - You can use `android:layout_marginTop` or `android:paddingTop`. — user370305, Jan 18 '13 at 16:08

android:layout_height="wrap_content" only works at certain times, for example, when you setHeight(), setWidth(), setText(), setMinHeight(), .... These methods will request the layout to wrap the content again.

But setTextSize() doesn't request the layout.

To trigger wrap_content to work again, you can call setMinHeight(0).
