如何在Android中更改ProgressBar的进度指示器颜色 [英] How to change ProgressBar's progress indicator color in Android

问题描述

我已经设置了水平ProgressBar.

我想将进度颜色更改为黄色.

I would like to change the progress color to yellow.

<ProgressBar 
    android:id="@+id/progressbar" 
    android:layout_width="80dip" 
    android:layout_height="20dip"  
    android:focusable="false" 
    style="?android:attr/progressBarStyleHorizontal" />

问题是，进度颜色在不同的设备中是不同的. 因此，我希望它可以修复进度颜色.

The problem is, the progress color is different in different devices. So, I want it to fix the progress color.

推荐答案

我从我的一个应用程序中复制了此代码，因此可能会有一些额外的属性，但应该可以给您带来启发.这来自具有进度条的布局:

I copied this from one of my apps, so there's prob a few extra attributes, but should give you the idea. This is from the layout that has the progress bar:

<ProgressBar
    android:id="@+id/ProgressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:indeterminate="false"
    android:maxHeight="10dip"
    android:minHeight="10dip"
    android:progress="50"
    android:progressDrawable="@drawable/greenprogress" />

然后使用类似于以下内容(在本例中为greenprogress.xml)创建一个新的可绘制对象:

Then create a new drawable with something similar to the following (In this case greenprogress.xml):

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <shape>
            <corners android:radius="5dip" />
            <gradient
                android:angle="270"
                android:centerColor="#ff5a5d5a"
                android:centerY="0.75"
                android:endColor="#ff747674"
                android:startColor="#ff9d9e9d" />
        </shape>
    </item>

    <item android:id="@android:id/secondaryProgress">
        <clip>
            <shape>
                <corners android:radius="5dip" />
                <gradient
                    android:angle="270"
                    android:centerColor="#80ffb600"
                    android:centerY="0.75"
                    android:endColor="#a0ffcb00"
                    android:startColor="#80ffd300" />
            </shape>
        </clip>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <corners android:radius="5dip" />
                <gradient
                    android:angle="270"
                    android:endColor="#008000"
                    android:startColor="#33FF33" />
            </shape>
        </clip>
    </item>

</layer-list>

您可以根据需要更改颜色，这将为您提供绿色的进度条.

You can change up the colors as needed, this will give you a green progress bar.
