我有一个textview,其背景是在xml文件中定义的。
<TextView
android:id="@+id/event_tvColor"
android:layout_width="40dip"
android:layout_height="40dip"
android:text=" "
android:background="@drawable/et_style_color_service_edit"
android:clickable="true"
/>
xml file : et_style_color_service_edit.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="@color/eventColor"/>
<stroke android:width="0sp" android:color="#FFFFFF" />
<size android:width="20dp"
android:height="20dp"/>
</shape>
我需要一次获得视图所具有的颜色。
ShapeDrawable sc = (ShapeDrawable)tvColor.getBackground();
...............
请注意,我需要使用ShapeDrawable而不是GradientDrawable。 感谢您的帮助和时间。
解........
Solution The xml loads into the app as a gradientdrawable and not as a shapedrawable. We have to define the shapeDrawable in java
ShapeDrawable sd = new ShapeDrawable(new RectShape);
sd.getPaint().setColor(0xFF0000FF);
如果有人有更好的解决方案可以说明。

经过进一步研究,目前无法获得xml加载的ShapeDrawable颜色。您需要做的就是跟踪您的颜色变化,以便了解您设置的颜色,即:
int currentColor = Color.WHITE; //this is the default color (color set in xml)
public void changeColor() {
if (currentColor == Color.WHITE) {
currentColor = Color.BLUE;
} else {
currentColor = Color.WHITE;
}
GradientDrawable gd = (GradientDrawable)tvColor.getBackground();
gd.setColor(currentColor);
}
