在每个 Viewpager 项目中执行线程

Question

• 我有两张图片，在单个浏览器项目中。当我点击任何图像时，它会显示一条线，简单的线。
• 我正在使用线程来增加这条线，线是给予特定图像的投票百分比，基于点击后在两个图像上绘制的百分比线

• 点击任意图片后想要两行，怎么办

Answer 1

以下是您处理当前问题的方法：

在您的活动/片段上编写一个方法来启动两行的动画。然后设置两个相同的OnClickListeners，每张图片一个，调用动画方法。

我更关心的是你在动画中使用Threads。这不是安卓的方式。您应该使用动画师对视图进行视觉更改。代码可以很简单：

        float pct = ... // ratio of votes to total votes, from 0.0 to 1.0

        vOne.setScaleX(0F);
        vOne.animate().setDuration(150).scaleXBy(pct).start();

请查看 Android 开发者网站和网络上其他地方的一些动画教程。
