or in <code>XML</code> this would be:

Set whether the <code>TextView</code> includes extra top and bottom padding to make room for accents that go above the normal ascent and descent. The default is true.

I feel your pain. I've tried every answer above, including the <code>setIncludeFontPadding</code> to false, which did nothing for me.

My solution? <code>layout_marginBottom="-3dp"</code> on the <code>TextView</code> gives you a solution for the bottom,
BAM! 

Although, -3dp on <code>layout_marginTop</code> fails....ugh.

blocks|key|1029373|text|这也惹恼了我，我发现的答案是，字体本身实际上有额外的空格，而不是TextView。这是相当恼人的，来自一个文档出版背景，你对Android对排版元素的控制是有限的。我建议使用可能没有这个问题的自定义字体(例如Bitstream+Vera+Sans，它被授权用于重新分发)。不过，我不确定它是否确实如此。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1029374|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This annoyed me too, and the answer I found was that there is actually additional space in the font itself, not the TextView. It is rather irritating, coming from a document publishing background, the limited amount of control you have with Android over typographic elements. I'd recommend using a custom typeface (such as Bitstream Vera Sans, which is licensed for redistribution) that may not have this issue. I'm not sure specifically whether or not it does, though.

Add android:includeFontPadding=&quot;false&quot; to see if it helps.And make text view size same as that of text size rather than &quot;wrap content&quot;.It will definitely work.

&lt;/RelativeLayout&gt;
</code></pre>

With an extra ImageView we can set the TextView to be baseline aligned with the ImageView and set the <code>android:baselineAlignBottom</code> on the ImageView to true, which will make the baseline of ImageView to bottom. Other views can align itself using the bottom of the ImageView which itself is the same as the TextView's baseline.

This however only fixes the padding bottom not the top.

I think this problem can be solved in this way:

 android:includeFontPadding="false"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:textSize="30dp"

 &lt;TextView
 android:id="@+id/rightUpperText"
 android:includeFontPadding="false"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_toRightOf="@+id/leftText"
 android:layout_alignTop="@+id/leftText"
 android:textSize="30dp"
 android:text="Hello World!" /&gt;

 &lt;TextView
 android:id="@+id/rightLowerText"
 android:includeFontPadding="false"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_toRightOf="@+id/leftText"
 android:layout_below="@+id/rightUpperText"
 android:textSize="30dp"
 android:text="hello world" /&gt;
</code></pre>

Those are the results:

<a href="https://i.stack.imgur.com/q2AoM.png" rel="nofollow noreferrer">ScreenShot-3</a>

Though the line of special characters in rightLowerText looks a little bit higher than the second line of leftText, their baselines are stilled aligned.

Simple method worked:

If it not worked, then try to add this above that code:

<pre><code>setLineSpacing(0f,0f);
// and set padding and margin to 0
</code></pre>

If you need multi line, maybe you'll need to calculate exactly the height of padding top and bottom via temp single line TextView (before and after remove padding) , then apply decrease height result with negative padding or some Ghost Layout with translate Y. Lol

To my knowledge this is inherent to most widgets and the amount of "padding" differs among phone manufacturers. This padding is really white space between the image border and the image in the 9 patch image file.

For example on my Droid X, spinner widgets get extra white space than buttons, which makes it look awkward when you have a spinner inline with a button, yet on my wife's phone the same application doesn't have the same problem and looks great!

The only suggestion I would have is to create your own 9 patch files and use them in your application.

Ahhh the pains that are Android.

Edited: Clarify padding vs white space.

Use constraintlayout as your root view then add a guideline helper.
Example:
<pre class="lang-xml prettyprint-override"><code>&lt;TextView

 app:layout_constraintStart_toStartOf=&quot;parent&quot; /&gt;

&lt;TextView
 android:id=&quot;@+id/textView2&quot;
 android:layout_width=&quot;wrap_content&quot;
 android:layout_height=&quot;wrap_content&quot; 
 app:layout_constraintStart_toStartOf=&quot;parent&quot;
 app:layout_constraintTop_toBottomOf=&quot;@+id/guideline&quot; /&gt;

&lt;androidx.constraintlayout.widget.Guideline

It seems that the background image of EditText has some transparent pixels which also add padding.

A solution is to change the default background of EditText to something else (or nothing, but no background for a EditText is probably not acceptable). That's can be made setting android:background XML attribute.

<pre><code>android:background="@drawable/myEditBackground"
</code></pre>

blocks|key|815007|text|在您的ImageView+xml中使用它|type|unstyled|depth|inlineStyleRanges|entityRanges|data|815008|android:adjustViewBounds="true“|815009|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Use this in your ImageView xml 

android:adjustViewBounds="true"

When I have a <code>TextView</code> with a <code>\n</code> in the text,, on the right I have two <code>singleLine</code> <code>TextView</code>s, one below the other with no spacing in between. I have set the following for all three <code>TextView</code>s.

<pre><code>android:lineSpacingMultiplier="1" 
android:lineSpacingExtra="0pt" 
android:paddingTop="0pt" 
android:paddingBottom="0pt"
</code></pre>

The first line of the left <code>TextView</code> lines up perfectly with the top right <code>TextView</code>. 

The second line of the left <code>TextView</code> is a little higher than the second line of the bottom right <code>TextView</code>.

It seems that there is some kind of hidden padding on the top and the bottom of the <code>TextView</code>s. How can I remove that?
