安卓：色调使用DrawableCompat [英] Android: Tint using DrawableCompat

问题描述

我想着色之前的Andr​​oid API级别21的图像我已经成功地用有色项目：

I'm trying to tint an image prior to Android API level 21. I've successfully tinted items using:

<android:tint="@color/red"/>

不过，我似乎无法弄清楚如何通过code上ImageView的做到这一点：

However, I can't seem to figure out how to do this through code on an ImageView:

Drawable iconDrawable = this.mContext.getResources().getDrawable(R.drawable.somedrawable);
DrawableCompat.setTint(iconDrawable, this.mContext.getResources().getColor(R.color.red));
imageView.setImageDrawable(iconDrawable);

我已经尝试设置TintMode但是这似乎使没有什么不同。我使用V4的兼容性类DrawableCompat不正确？

I've tried setting the TintMode but this seems to make no different. Am I using the v4 compatibility class DrawableCompat incorrectly?

推荐答案

不是由 DrawableCompat 支持previously着色。 从支持库22.1起，你可以做到这一点，但你需要做的是这样的：

Previously tinting was not supported by DrawableCompat. Starting from support library 22.1 you can do that, but you need do it in this way:

Drawable normalDrawable = getResources().getDrawable(R.drawable.drawable_to_tint);
Drawable wrapDrawable = DrawableCompat.wrap(normalDrawable);
DrawableCompat.setTint(wrapDrawable, getResources().getColor(R.color.colorPrimaryLight));
