如何使搜索栏占用母公司全宽 [英] How to make SeekBar take up full width of parent

问题描述

我有一个搜索栏在 RelativeLayout的，其宽度等于屏幕的宽度。

I have a SeekBar in a RelativeLayout whose width is equal to the screen width.

我申请 layout_width =match_parent到搜索栏，但它似乎让双方都有点空的搜索栏，以容纳拇指。

I applied layout_width="match_parent" to the SeekBar but it seems to keep some empty space on both sides of the SeekBar to accommodate the thumb.

我也尝试过使用机器人：拇指=@空拇指走了​​，但不是在两侧的空

I also tried using android:thumb="@null" The thumb is gone but not the empty space on the sides.

我真的需要让搜索栏宽度匹配父。可能有人帮助我？也许我可以创建自定义的搜索栏类，并设置宽度为母公司宽度 onMeasure （）。如果这是一个可行的解决方案，我不知道我怎么能传递父宽度与搜索栏类。

I really need to make the SeekBar width match the parent's. Could somebody help me with this? Maybe I could create a custom SeekBar class and set the width to the parent width in onMeasure(). If this is a possible solution, I don't know how I could pass the parent width to the SeekBar class.

任何帮助是AP preciated。谢谢你。

Any help is appreciated. Thank you.
