[英]Android : No resource identifier found for attribute 'headerView'
使用Android Studio,我在活動布局中收到此錯誤: Error:(9) No resource identifier found for attribute 'headerView' in package 'com.merahjambutech.zuki.deteksi'
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
xmlns:compat="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<com.merahjambutech.zuki.deteksi.view.PullToZoomListViewEx
android:id="@+id/paralax_social_list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="@android:color/transparent"
app:headerView="@layout/header_parallax_social" />
</LinearLayout>
我非常確定我的項目文件(res / layout)中的布局header_parallax_social.xml是可用的,這里是header_parallax_social的代碼:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="160dp" >
<ImageView
android:id="@+id/header_parallax_social_new_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_centerVertical="true"
android:layout_gravity="center_horizontal"
android:contentDescription="@string/cd_main_image"
android:scaleType="centerCrop"
android:src="@drawable/parallax_social_small" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
我試圖改變xmlns:app和類似的東西,但仍未找到解決方案......
你必須設置自定義屬性即headerView您的Listview
中attrs.xml
中values
的文件夾:
attrs.xml
<resources>
<declare-styleable name="PullToZoomListViewEx"> declare your custom listview class name here
<attr name="headerView" format="reference"/>
</declare-styleable>
</resources>
通過這樣做我希望app:headerView="@layout/header_parallax_social"
不會顯示任何錯誤,但要在列表視圖中顯示標題視圖,您必須在自定義Listview類中進行一些更改,它應該看起來像
public class PullToZoomListViewEx extends ListView{
private int headerId;
public PullToZoomListViewEx(Context context) {
super(context);
}
public PullToZoomListViewEx(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public PullToZoomListViewEx(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
TypedArray a = context.getTheme().obtainStyledAttributes(attrs, R.styleable.PullToZoomListViewEx, defStyle, defStyle);
try {
headerId = a.getResourceId(R.styleable.PullToZoomListViewEx_headerView, View.NO_ID);
if (headerId != View.NO_ID) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View header = inflater.inflate(headerId, null);
addHeaderView(header);
}
} finally {
a.recycle();
}
}
}
要么
如果您想避免上述工作,可以通過編程方式將標題視圖設置為Listview,如下所示:
LayoutInflater inflater = getLayoutInflater();
ViewGroup header = (ViewGroup)inflater.inflate(R.layout.header,myListView, false);
//replace R.layout.header with R.layout.header_parallax_social and myListView with your listview object
myListView.addHeaderView(header, null, false);
希望這可以幫助。
