Applying ColorFilter to ImageView with ShapedDrawable
提问by aplavin
I have an ImageViewwith android:srcset to a ShapedDrawable, namely a white circle. What I want is to colorize this ImageViewin runtime responding to some events. imgView.setColorFilterseems to be solution, but after using this (tried different parameters) the image becomes invisible (I don't see it at the screen).
我有一个ImageViewwithandroid:src设置为 a ShapedDrawable，即一个白色圆圈。我想要的是ImageView在响应某些事件的运行时为它着色。imgView.setColorFilter似乎是解决方案，但是在使用这个（尝试了不同的参数）之后，图像变得不可见（我在屏幕上看不到它）。
How to solve this? And are there better ways to have color circles?
如何解决这个问题？有没有更好的方法来制作色环？

Alright, I had a quick play with this and noticed your issue of the circles disappearing. Without you describing whatexactly you tried, I assume you haven't tried setting the color filter to the Drawableitself yet? (as opposed to the ImageView, which only seems to work with BitmapDrawables).
好的，我对此进行了快速播放，并注意到您的圆圈消失的问题。没有你描述你到底尝试了什么，我假设你还没有尝试将滤色器设置为它Drawable本身？（相对于ImageView，它似乎只适用于BitmapDrawables）。
The following statements work perfectly fine for an xml-declared ShapeDrawablewith white as initial color:
以下语句对于ShapeDrawable以白色作为初始颜色的 xml 声明完全正常：
ImageView redCircle = (ImageView) findViewById(R.id.circle_red_imageview);
ImageView greenCircle = (ImageView) findViewById(R.id.circle_green_imageview);
ImageView blueCircle = (ImageView) findViewById(R.id.circle_blue_imageview);
// we can create the color values in different ways:
redCircle.getDrawable().setColorFilter(Color.RED, PorterDuff.Mode.MULTIPLY );
greenCircle.getDrawable().setColorFilter(0xff00ff00, PorterDuff.Mode.MULTIPLY );
blueCircle.getDrawable().setColorFilter(getResources().getColor(R.color.blue), PorterDuff.Mode.MULTIPLY );
The ShapeDrawablefor completeness: (I set the size on the ImageView, see below)
该ShapeDrawable物品是否完整：（我设置的大小ImageView，见下文）
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
<solid android:color="@android:color/white" />
</shape>
And one of the ImageViews as example:
以ImageViews之一为例：
<ImageView
android:id="@+id/circle_red_imageview"
android:layout_width="40dp"
android:layout_height="40dp"
android:padding="5dp"
android:src="@drawable/circle_white" />
Visual result:

If you want to change Image Color use
如果你想改变图像颜色使用
PorterDuff.Mode.SRC_ATOP instead
PorterDuff.Mode.MULTIPLY
in above example.
在上面的例子中。

You can use attribute android:tintin ImageView in xml.
您可以android:tint在 xml 中的 ImageView 中使用属性。
Example:
例子：
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/your_drawable"
android:tint="@color/your_color" />
Tested on Android 4.1.2 and 6.0.1

You can do it very very simple using this library: https://github.com/jrvansuita/IconHandler
您可以使用此库非常简单地完成此操作：https: //github.com/jrvansuita/IconHandler
It will working like this:
它将像这样工作：
Icon.on(yourImageView).color(R.color.your_color).icon(R.mipmap.your_icon).put();
