erchenger / sizeadjustingtextview Goto Github PK

All I wanted is that it would fit into it boundaries.

Using the next XML will make it very slow and also truncate the text:

<com.omitneedlesscode.sizeadjustingtextview.SizeAdjustingTextView
    android:layout_width="180dp"
    android:layout_height="203dp"
    android:layout_below="@+id/text_input"
    android:maxLines="2"
    android:text="content text sample"
    android:textSize="1000dp"/>

And this is what I got :

plus it was very slow.

note that I've set 1000dp so that it will resize to the max that it can. a better way is to do it in code.

I think it should work this way:
using the current configurations of the TextView, if it failed to fit, try to find a font that will make it fit.
if failed with this, try to add a line (till reaching max lines that were set), and for each iteration there try to fit the font.

For the font checking, I think it should use binary search, instead of decreasing by 1 .

Can you also include an example project?

Hi!
Please set screenshots.

so that we could use it easily.

Here's how to fix it.

private float findNewTextSize(int width, int height, CharSequence text) {
        TextPaint textPaint = new TextPaint(getPaint());
        float targetTextSize = getMaxTextSize();  // Start from the max size
        int textHeight = getTextHeight(text, textPaint, width, targetTextSize);
        while(textHeight > height && targetTextSize > mMinTextSize) {
            targetTextSize = Math.max(targetTextSize - 1, mMinTextSize);
            textHeight = getTextHeight(text, textPaint, width, targetTextSize);
        }
        return targetTextSize;
    }
