[英]TypedArray getColor always returns defValue
在我的XML元素中,我尝试从colors.xml资源文件中传递颜色。 getColor函数总是返回defValue,即使它应该返回colors.xml中给出的颜色。
TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.accordion);
final int col_pressed = a.getColor(R.styleable.accordion_buttonColorPressed, Color.BLACK);
final int col_unpressed = a.getColor(R.styleable.accordion_buttonColorPressed, Color.YELLOW);
btn.setBackgroundColor(col_unpressed);
<mika.actual.AccordionWidget
xmlns:accordion="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
accordion:text_color="@color/text_color"
accordion:buttonColorPressed="@color/button_pressed"
accordion:buttonColorUnpressed="@color/button_not_pressed"
android:background="#FFFFFFFF"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="vertical"> ... </mika.actual.AccordionWidget>

这是一个老线程,但没有人回应。 我会的,所以观众可以得到一个答案,我认为你只需要改变你所有的accordion:
app:
就像这样
app:text_color="@color/text_color"
app:buttonColorPressed="@color/button_pressed"
app:buttonColorUnpressed="@color/button_not_pressed"
