棒棒糖进度栏着色 [英] Lollipop Progress Bar Tinting

问题描述

我在Lollipop设备上(MotoG 2014)，我读到有关进度条着色的信息，但这不起作用...我得到了默认的进度条颜色.我在这里想念什么?

I'm on a Lollipop device (MotoG 2014), I read about progress bar tinting, but this is not working...I get the default progress bar color. What am I missing here?

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:backgroundTintMode="src_in"
    android:indeterminate="true"
    android:indeterminateTint="#f00" />

非常感谢.

推荐答案

在Lollipop之前的版本中，可接受的解决方案不适用于我，但是我发现该解决方案适合所有API，但最重要的是，使用任何不推荐使用的代码:

The accepted solution wasn't working for me on pre-Lollipop, but I found this solution to fit all APIs and on top of that, it doesn't use any deprecated code:

Java解决方案

// 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);
}

Kotlin扩展

fun ProgressBar.setIndeterminateTintCompat(@ColorInt color: Int) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
        val wrapDrawable = DrawableCompat.wrap(indeterminateDrawable)
        DrawableCompat.setTint(wrapDrawable, color)
        indeterminateDrawable = DrawableCompat.unwrap(wrapDrawable)
    } else {
        indeterminateTintList = ColorStateList.valueOf(color)
    }
}

// usage

val desiredColor = ContextCompat.getColor(context, R.color.myColor)
myProgressBar.setIndeterminateTintCompat(desiredColor)

编码愉快！
