Android: TextView: Remove spacing and padding on t

Question

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

android:lineSpacingMultiplier="1" 
android:lineSpacingExtra="0pt" 
android:paddingTop="0pt" 
android:paddingBottom="0pt"

The first line of the left TextView lines up perfectly with the top right TextView.

The second line of the left TextView is a little higher than the second line of the bottom right TextView.

It seems that there is some kind of hidden padding on the top and the bottom of the TextViews. How can I remove that?

Answer 1

See this:

Align ImageView with EditText horizontally

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.

android:background="@drawable/myEditBackground"

Answer 2

Since my requirement is override the existing textView get from findViewById(getResources().getIdentifier("xxx", "id", "android"));, so I can't simply try onDraw() of other answer.

But I just figure out the correct steps to fixed my problem, here is the final result from Layout Inspector:

Since what I wanted is merely remove the top spaces, so I don't have to choose other font to remove bottom spaces.

Here is the critical code to fixed it:

Typeface mfont = Typeface.createFromAsset(getResources().getAssets(), "fonts/myCustomFont.otf");
myTextView.setTypeface(mfont);

myTextView.setPadding(0, 0, 0, 0);

myTextView.setIncludeFontPadding(false);

The first key is set custom font "fonts/myCustomFont.otf" which has the space on bottom but not on the top, you can easily figure out this by open otf file and click any font in android Studio:

As you can see, the cursor on the bottom has extra spacing but not on the top, so it fixed my problem.

The second key is you can't simply skip any of the code, otherwise it might not works. That's the reason you can found some people comment that an answer is working and some other people comment that it's not working.

Let's illustrated what will happen if I remove one of them.

Without setTypeface(mfont);:

Without setPadding(0, 0, 0, 0);:

Without setIncludeFontPadding(false);:

Without 3 of them (i.e. the original):

Answer 3

Only thing that worked is

android:lineSpacingExtra="-8dp"

Answer 4

Simple method worked:

setSingleLine();
setIncludeFontPadding(false);

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

setLineSpacing(0f,0f);
// and set padding and margin to 0

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
