我有一个自定义视图,使用这些构造函数扩展LinearLayout:
public class CustomView extends LinearLayout {
public CustomView(Context context) {
this(context, null);
}
public CustomView(Context context, AttributeSet attrs) {
this(context, attrs, R.attr.customViewStyle);
}
public CustomView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
/* set custom attributes with TypedArray */
}
/* other methods */
}
在我的/res/values/attrs.xml中:
<attr name="customViewStyle" format="reference" />
<declare-styleable name="CustomeView">
<attr name="value" format="integer" />
<attr name="android:imeOptions" />
<attr name="android:imeActionId" />
<attr name="android:imeActionLabel" />
</declare-styleable>
在我的/res/values/styles.xml中:
<style name="AppTheme" parent="@android:style/Theme.Black">
<item name="android:windowBackground">@drawable/bg_dark_fiber</item>
<item name="customViewStyle">@style/CustomViewStyle</item>
