I'm trying to make a text as big as I can making it fit a Rect.
basically I use a StaticLayout for pre-calculate the text size and make it fit the Rect's height:
// Since the width is fixed for the StaticLayout it should only fit the height
while (currentHeight>Rect.getHeight()){
size-=2;
}
textPaint.setTextSize(size);
The problem is that if the Rect is very high, the exit condition is reached but breaking the words (see the capture). Is there a way for avoid this?
Goal:
Actual:
Current code:
textSize=MAX_TEXT_SIZE
do {
if (textSize < mMinTextSize) {
Log.i(TAG, "Min reached");
textSize = mMinTextSize;
textPaint.setTextSize(textSize);
fits = true;
} else {
textPaint.setTextSize(textSize);
StaticLayout layout = new StaticLayout(text, textPaint, targetWidth, Alignment.ALIGN_NORMAL, 1.0,
0, true);
layout.draw(canvas);
float heightRatio= (float) layout.getHeight() / (float) targetHeight;
boolean fitsHeight = heightRatio<= 1f;
if (fitsHeight) {
fits = true;
} else {
textSize -= 2;
}
}
Log.i(TAG, "textSize=" + textSize + " fits=" + fits);
} while (!fits);
thanks
