如果有人想通过编程改变颜色:

progressBar.progressTintList = ColorStateList.valueOf(Color.RED)

我知道我迟到了，但如果你只想改变进度条的颜色，这是最简单的解决方案，在你的主题中，只需添加，

@color - your_color

colorSecondary将改变你整个进程的颜色。

在修改默认进度条的外观时遇到了同样的问题。这里有一些更多的信息，希望能帮助到人们:)

The name of the xml file must only contain characters: a-z0-9_. (ie. no capitals!) To reference your "drawable" it is R.drawable.filename To override the default look, you use myProgressBar.setProgressDrawable(...), however you need can't just refer to your custom layout as R.drawable.filename, you need to retrieve it as a Drawable:Resources res = getResources(); myProgressBar.setProgressDrawable(res.getDrawable(R.drawable.filename); You need to set style before setting progress/secondary progress/max (setting it afterwards for me resulted in an 'empty' progress bar)

很抱歉，这不是答案，但是是什么驱使需求从代码中设置它呢? 如果定义正确。setprogressdrawable应该工作

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

<item android:id="@android:id/background">
    <shape>
        <corners android:radius="5dip" />
        <gradient
                android:startColor="#ff9d9e9d"
                android:centerColor="#ff5a5d5a"
                android:centerY="0.75"
                android:endColor="#ff747674"
                android:angle="270"
        />
    </shape>
</item>

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

<item android:id="@android:id/progress">
    <clip>
        <shape>
            <corners
                android:radius="5dip" />
            <gradient
                android:startColor="@color/progress_start"
                android:endColor="@color/progress_end"
                android:angle="270" 
            />
        </shape>
    </clip>
</item>

</layer-list>

适用于SDK 21及以上版本

android:indeterminateTint="@color/orange"

对我来说是很简单的。

根据一些建议，你可以指定一个形状和可剪切的颜色，然后设置它。我让它以编程的方式工作。我就是这么做的。

首先确保导入了可绘制库。

进口android.graphics.drawable。*;

然后使用类似于下面的代码;

ProgressBar pg = (ProgressBar)row.findViewById(R.id.progress);
final float[] roundedCorners = new float[] { 5, 5, 5, 5, 5, 5, 5, 5 };
pgDrawable = new ShapeDrawable(new RoundRectShape(roundedCorners, null,null));
String MyColor = "#FF00FF";
pgDrawable.getPaint().setColor(Color.parseColor(MyColor));
ClipDrawable progress = new ClipDrawable(pgDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
pg.setProgressDrawable(progress);   
pg.setBackgroundDrawable(getResources().getDrawable(android.R.drawable.progress_horizontal));
pg.setProgress(45);
