我在我的Android应用程序中使用水平进度条,我想改变它的进度颜色(默认为黄色)。我如何使用代码(而不是XML)做到这一点?

简单的使用方法:

PorterDuff.Mode mode = PorterDuff.Mode.SRC_IN;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
    mode = PorterDuff.Mode.MULTIPLY;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));
    progressBar.setProgressBackgroundTintList(ColorStateList.valueOf(Color.RED));
} else {
    Drawable progressDrawable;
    progressDrawable = (progressBar.isIndeterminate() ? progressBar.getIndeterminateDrawable() : progressBar.getProgressDrawable()).mutate();
    progressDrawable.setColorFilter(context.getResources().getColor(Color.RED), mode);
    progressBar.setProgressDrawable(progressDrawable);
}

android:progressTint="#ffffff" 

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>

这招对我很管用:

<ProgressBar
 android:indeterminateTint="#d60909"
 ... />

如今在2016年,我发现一些前棒棒糖设备不尊重colorAccent设置,所以我对所有api的最终解决方案现在如下:

// fixes pre-Lollipop progressBar indeterminateDrawable tinting
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {

    Drawable wrapDrawable = DrawableCompat.wrap(mProgressBar.getIndeterminateDrawable());
    DrawableCompat.setTint(wrapDrawable, ContextCompat.getColor(getContext(), android.R.color.holo_green_light));
    mProgressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
} else {
    mProgressBar.getIndeterminateDrawable().setColorFilter(ContextCompat.getColor(getContext(), android.R.color.holo_green_light), PorterDuff.Mode.SRC_IN);
}

另外,它没有使用任何弃用代码。试一试!

简单的使用方法:

PorterDuff.Mode mode = PorterDuff.Mode.SRC_IN;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
    mode = PorterDuff.Mode.MULTIPLY;
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));
    progressBar.setProgressBackgroundTintList(ColorStateList.valueOf(Color.RED));
} else {
    Drawable progressDrawable;
    progressDrawable = (progressBar.isIndeterminate() ? progressBar.getIndeterminateDrawable() : progressBar.getProgressDrawable()).mutate();
    progressDrawable.setColorFilter(context.getResources().getColor(Color.RED), mode);
    progressBar.setProgressDrawable(progressDrawable);
}
