Example 1
private void chooseSize(PopupWindow pop, CharSequence text, TextView tv) {
	int wid = tv.getPaddingLeft() + tv.getPaddingRight();
	int ht = tv.getPaddingTop() + tv.getPaddingBottom();

	/*
	 * Figure out how big the text would be if we laid it out to the
	 * full width of this view minus the border.
	 */
	int cap = getWidth() - wid;
	if (cap < 0) {
		cap = 200; // We must not be measured yet -- setFrame() will fix it.
	}

	Layout l = new StaticLayout(text, tv.getPaint(), cap,
			Layout.Alignment.ALIGN_NORMAL, 1, 0, true);
	float max = 0;
	for (int i = 0; i < l.getLineCount(); i++) {
		max = Math.max(max, l.getLineWidth(i));
	}

	/*
	 * Now set the popup size to be big enough for the text plus the border.
	 */
	pop.setWidth(wid + (int) Math.ceil(max));
	pop.setHeight(ht + l.getHeight());
