廢話不多說先看效果圖
效果圖
原諒模擬器顯示的不好看，為了錄gif圖，只能用模擬器
乙個背景，乙個進度，乙個進度值顯示，進度條與文字顯示的高度是1：2，其中用到了drawroundrect用來畫帶圓角的矩形，空心與實心都是paint的屬性設定的，drawtext用來畫文字
注意點：
1.進度條進度滿進度與未滿進度，計算onewidth = mwidth / mmaxprogress(單位進度佔的寬度=總寬度／滿進度);
2.文字顯示，先計算文字的寬度，三個狀態(起始位置 <= 文字寬度 / 當前位置 +文字寬度》=寬度/之間的)，分別進行計算
ondraw來畫圖了
@override
protected void ondraw(canvas canvas) else
canvas.drawroundrect(rectfm, num8, num8, mpaint);
//畫文字
//獲取文字的寬度及其高度
rect rect = new rect();
string speed = mcurrentprogress + "%";
txtpaint.gettextbounds(speed, 0, speed.length(), rect);
textheight = rect.height();
textwidth = rect.width();
if (mcurrentprogress == mmaxprogress) else else
if (x + textwidth >= mwidth) else
