如何将drawable set的颜色改为android：background？

I have an icon which look like this:icon in my constraint layout.

我有一个看起来像这样的图标：约束布局中的图标。

This is my layout xml for this image view:

这是此图像视图的布局xml：

<ImageView
        android:id="@+id/vTotalPaidAvatar"
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:contentDescription="@null"
        android:src="@drawable/ic_group_ic_total"
        tools:src="@drawable/ic_group_ic_total"
        app:layout_constraintLeft_toLeftOf="@+id/vSettleDebtsLayout"
        android:layout_marginLeft="16dp"
        android:layout_marginStart="16dp"
        app:layout_constraintTop_toTopOf="@+id/vSettleDebtsLayout"
        android:layout_marginTop="16dp"
        android:background="@drawable/avatar_circle" />

As you can see, the icon is just a dollar sign. I set that grey circle as background. The problem is that I need to change color of that background dynamically. The dollar sign need to stay white. My question is, is there any way how to change only the color of background?

如您所见，图标只是一个美元符号。我将那个灰色圆圈设为背景。问题是我需要动态更改该背景的颜色。美元符号需要保持白色。我的问题是，有没有办法如何只改变背景的颜色？

Another solution would be to use that circle as next imageview and then change color of that image view. But i think that there could be some more "clear solution for this issue.

另一种解决方案是将该圆圈用作下一个图像视图，然后更改该图像视图的颜色。但我认为可能会有更明确的解决方案来解决这个问题。

Thanks for tips :)

谢谢你的提示:)

4 个解决方案

#1

Try:

尝试：

yourImage.getBackground().setColorFilter(color, PorterDuff.Mode.SRC_IN);

This literally gets background (without src) from ImageView and covers its shape with color. The way the drawable and given color are combining is defined by mode of Porter Duff - here you have more about it.

这从字面上获取ImageView的背景（没有src）并用颜色覆盖它的形状。可绘制和给定颜色组合的方式由Porter Duff模式定义 - 在这里您可以了解更多信息。

Best way to do it:

最好的方法：

public static void colorDrawable(View view, int color) {
    Drawable wrappedDrawable = DrawableCompat.wrap(view.getBackground());
    if (wrappedDrawable != null) {
        DrawableCompat.setTint(wrappedDrawable.mutate(), color);
        setBackgroundDrawable(view, wrappedDrawable);
    }
}

public static void setBackgroundDrawable(View view, Drawable drawable) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
        view.setBackgroundDrawable(drawable);
    } else {
        view.setBackground(drawable);
    }
}

#3

Well u must try

你必须尝试

android:backgroundTint="your color"

in imageview tag

在imageview标签中

this will do the work

这将完成工作

#4

Did you try android:background="@color/my_color" and through code imageView.setBackgroundColor(Color.rgb(255, 255, 255)); ?

你尝试过android：background =“@ color / my_color”并通过代码imageView.setBackgroundColor（Color.rgb（255,255,255））; ？
