私のプロジェクトには、button(btnList)を含むlistView(homelistView)が含まれています。
ボタン(btnList)をクリックすると、別のアクティビティに移動する必要があります。たくさん試しましたが、良い例が見つかりませんでした。
これに関する良い例を教えてください。
以下は私のコードです:
これが私のリストビューに含まれるボタンです。ボタンをクリックすると、他のアクティビティに移動する必要があります
--------------------------------A--
button(btnList) B
--------------------------------C---
BUTTON(btnList) D
--------------------------------E--
homempleb.xmlxmlでこのコードを使用する前。Mohith vermaのサンプルによると、ボタンリストは問題なく機能しました
<ListView
android:id="@+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04"
android:dividerHeight="0dip" >
</ListView>
homempleb.xml現在、リストビューにスクロールインデックスを追加し、以下のようにコードを変更しました。リストボタンが機能していません。Plzが私を助けてくれます。
<com.woozzu.android.widget.IndexableListView
android:id="@+id/homelistView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04"
android:dividerHeight="0dip" >
</com.woozzu.android.widget.IndexableListView>
