两种计算Text文本的尺寸的区别

(1)

通过getTextBounds的方式获取Text的绘制尺寸

/***
 * 通过getTextBounds的方式获取Text的绘制尺寸
 * @param text
 * @return
 */
private int[] getTextMeasurementByBound(String text){
    Rect textRect = new Rect();
    Paint selectedItemPaint = new Paint();
    selectedItemPaint.getTextBounds(text, 0, text.length(), textRect);
    int measureHeight = textRect.height();
    int measureWidth = textRect.width();
    return new int[]{measureHeight, measureWidth};
}

(2)通过Layout测量的方式获取Text的绘制尺寸

/***
 * 通过Layout测量的方式获取尺寸
 * @param text
 * @return
 */
private int getTextMeasurementByLayout(String text){
    Rect textRect = new Rect();
    Paint selectedItemPaint = new TextPaint();
    int measureHeight = Layout.getDesiredWidth(text, selectedItemPaint);
    return measureHeight;
}
