How to remove the top and bottom space on textview of Android

Question

When I include the below XML to layout file, I can see the below image. If you see it, you could realize that the TextView has top and bot

Answer 1

android:includeFontPadding="false" is pretty good but it does not get it precisely. sometimes you want border line accuracy so you can figure it out yourself by applying negative margins:

try setting your bottom and top margins to a negative value.

something like this:

android:layout_marginTop="-5dp"
android:layout_marginBottom="-5dp"

adjust the values accordingly.

Answer 2

This is the code that saved our day. It was adapted using mono C# code from maksimko:

public class TopAlignedTextView extends TextView {

    public TopAlignedTextView(Context context) {
        super(context);
    }

    /*This is where the magic happens*/
    @Override
    protected void onDraw(Canvas canvas){

        float offset = getTextSize() - getLineHeight();
        canvas.translate(0, offset);
        super.onDraw(canvas);
    }
}

Still had to play around with textView.setIncludeFontPadding(false) because we were aligning TextViews with different font sizes.

Answer 3

I had the same problem. Attribute android:includeFontPadding="false" does not work for me. I've solved this problem in this way:

public class TextViewWithoutPaddings extends TextView {

    private final Paint mPaint = new Paint();

    private final Rect mBounds = new Rect();

    public TextViewWithoutPaddings(Context context) {
        super(context);
    }

    public TextViewWithoutPaddings(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TextViewWithoutPaddings(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onDraw(@NonNull Canvas canvas) {
        final String text = calculateTextParams();

        final int left = mBounds.left;
        final int bottom = mBounds.bottom;
        mBounds.offset(-mBounds.left, -mBounds.top);
        mPaint.setAntiAlias(true);
        mPaint.setColor(getCurrentTextColor());
        canvas.drawText(text, -left, mBounds.bottom - bottom, mPaint);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        calculateTextParams();
        setMeasuredDimension(mBounds.width() + 1, -mBounds.top + 1);
    }

    private String calculateTextParams() {
        final String text = getText().toString();
        final int textLength = text.length();
        mPaint.setTextSize(getTextSize());
        mPaint.getTextBounds(text, 0, textLength, mBounds);
        if (textLength == 0) {
            mBounds.right = mBounds.left;
        }
        return text;
    }
}

Answer 4

android:includeFontPadding="false"

Answer 5

Try android:includeFontPadding="false" to see if it helps. In my experience that will help a little bit, but there's no way of reducing the TextView dimensions to the exact pixel-perfect text size.

The only alternative, which may or may not give better results, is to cheat a bit and hard-wire the dimensions to match the text size, e.g. "24sp" instead of "wrap_content" for the height.

Answer 6

Have you defined a layout margin? For example:

android:layout_marginTop="5dp"

Otherwise, if your text view is wrapped inside a LinearLayout or other container, then that cold have either padding or a margin too.
