Example 21 with StaticLayout

use of android.text.StaticLayout in project WordPress-Android by wordpress-mobile.

the class AutoResizeTextView method getTextHeight.

// Set the text size of the text paint object and use a static layout to render text off screen before measuring
private int getTextHeight(CharSequence source, TextPaint paint, int width, float textSize) {
    // modified: make a copy of the original TextPaint object for measuring
    // (apparently the object gets modified while measuring, see also the
    // docs for TextView.getPaint() (which states to access it read-only)
    TextPaint paintCopy = new TextPaint(paint);
    // Update the text paint object
    paintCopy.setTextSize(textSize);
    // Measure using a static layout
    StaticLayout layout = new StaticLayout(source, paintCopy, width, Layout.Alignment.ALIGN_NORMAL, mSpacingMult, mSpacingAdd, true);
    return layout.getHeight();
