問題描述

我有兩個問題:

1) 如何將搜索欄(路徑)的顏色從黃色(默認顏色)更改為白色.我的意思是，當我滑動拇指時，它會將穿過的線從灰色變為黃色.我希望軌道/線保持灰色或白色.基本上我只希望拇指移動而在搜索欄中沒有顏色變化.

1) how do I change the color of the seek bar (path) from yellow (the default color) to white. What I mean to say is, while I slide the thumb , it turns the line traversed from grey to yellow. I want track/line to either remain grey or white..Basically I want just the thumb to move with no color change in the seek bar.

2)如何將搜索欄的拇指從矩形更改為圓形/球形/圓形.

2) How to change the thumb of seekbar from rectangle to circle/sphere/round shape.

任何指針將不勝感激.

我想為剛接觸系統的人完成上面的答案，

I want to complete the answer from above for the people who are new to the system,

缺少的 xmls( background_fill ， progress_fill 和 progress 可能看起來像漸變紅色

the missing xmls ( background_fill , progress_fill and progress could look like that for a gradient red

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item 
            android:id="@android:id/background" 
            android:drawable="@drawable/background_fill" />

        <item android:id="@android:id/progress">
           <clip android:drawable="@drawable/progress_fill" />
        </item>
  </layer-list>

background_fill.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient 
        android:startColor="#FF555555" 
        android:centerColor="#FF555555"
        android:endColor="#FF555555" 
        android:angle="90" />

    <corners android:radius="5px" />

    <stroke 
        android:width="2dp" 
        android:color="#50999999" />

    <stroke 
        android:width="1dp" 
        android:color="#70555555" />
</shape>

progress_fill.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient 
        android:startColor="#FF470000" 
        android:centerColor="#FFB80000"
        android:endColor="#FFFF4400" 
        android:angle="180" />

    <corners android:radius="5px" />

    <stroke 
            android:width="2dp" 
            android:color="#50999999" />

    <stroke 
            android:width="1dp" 
            android:color="#70555555" />
</shape>

我沒有完成android:thumb的實現，所以拇指還是原來的那個

i did not complete the implementing for android:thumb, so the thumb will be still the original one

因此，我們只需從定義搜索欄的布局 xml 中再次刪除這一行

Therefore we just have to delete this line again from our layout xml where we define the seekbar

android:thumb="@drawable/thumb"

祝你好運！！！
