推荐答案

有数量解决问题的方法：

There's number to solutions to the problem:

• 使用为backgorund 9patch 图像（这基本上应的用作背景搜索栏）。如下所示：

• Use 9patch image for backgorund (which is basically should be used as background for seekbar). Like the following:

（名称应为 unselect_patch.9.png ），并稍微修改 custom_seekbar.xml 来如下所示：

(name should be unselect_patch.9.png) and slightly modify custom_seekbar.xml to look like the following:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@android:id/background"
        android:drawable="@drawable/unselect_patch"/>
    <item android:id="@android:id/secondaryProgress">
        <clip>
            <bitmap xmlns:android="http://schemas.android.com/apk/res/android"
                android:src="@drawable/select"
                android:tileMode="disabled" />
        </clip>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <bitmap xmlns:android="http://schemas.android.com/apk/res/android"
                android:src="@drawable/select"
                android:tileMode="disabled" />
        </clip>
    </item>

</layer-list>

• 就在布局提供图像的确切大小（例如 layout_width =@扪/ select_image_width）;

• Just provide exact size of the image in layout (e.g. layout_width="@dimen/select_image_width");

要支持所有决议案 - 为不同分辨率提供图像，rel=\"nofollow\">支持多种屏幕中。相同的图像将无法正常工作的所有决议和这里的好只是按照上面的链接中详细描述的最佳做法。

To support all resolutions - provide images for different resolutions, as described in Supporting Multiple Screens. The same images will not work fine for all resolutions and here's better just follow best practices described in detail at the link above.
