チェックボックスと検索機能を備えたリストビューを作成しました。検索は正常に機能しており、チェックボックスも表示されています。今私が欲しいのは、ボタンのクリックですべてのチェックされたリスト項目の名前を取得したいということです。また、アイテム名の下に価格など、別のテキストビューを表示する方法を知りたいです。
メインレイアウト：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<!-- Editext for Search -->
<EditText
android:id="@+id/inputSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Search products.."
android:inputType="textVisiblePassword" />
<ListView
android:id="@+id/mainListView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</ListView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="5dp"
android:onClick="showResult"
android:text="Show Result" >
</Button>
</LinearLayout>
simplerow.xmlファイル:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/rowTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="bold"
android:textSize="16sp" >
</TextView>
<CheckBox android:id="@+id/CheckBox01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:layout_alignParentRight="true" android:layout_marginRight="6sp"
