碰到动态改变Drawble的颜色的需要,记录一下

创建一个shape在/drawble/t_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/darkBG"></solid>
    <corners android:radius="4dp"/>
</shape>

然后需要动态改变color

首先要获得Drawble

Drawable tagShapeDrawable = Drawable.createFromXml(context.getResources(), context.getResources().getXml(R.drawable.tag_shape));

然后

tagShapeDrawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
view.setBackground(tagShapeDrawable);
