Android中滑动的缩小Seekbar按钮（带有自己的thumb xml）

我对Android SeekBar有问题

当我使用标准thumb（蓝色）时，它是可以的，但当我使用自己的主题（如scriber_control.xml）时，会出现问题——按钮的范围缩小了。我尝试过设置最小高度、填充、为洗涤器控制项添加高度/宽度，但无法解决这个奇怪的问题

布局

洗涤器控制.xml

---

在drawables中创建自定义形状XML，用于定义拇指的高度和宽度

用于scriber_control.xml中使用的所有三种形状

例如：

在drawable文件夹中添加这些XML

之后，您只需要像这样更改选择器

<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_enabled="false"  android:drawable="@drawable/custom_scrubber_control_disabled_holo" />
 <item android:state_pressed="true" android:drawable="@drawable/custom_scrubber_control_pressed_holo" />
 <item android:state_selected="true" android:drawable="@drawable/custom_scrubber_control_focused_holo" />
 <item android:drawable="@drawable/custom_scrubber_control_normal_holo" />
 </selector>
