listview에 약간의 문제가 있습니다. 버튼을 클릭 할 때 checkbox가 선택된 listview 값을 가져 오려고합니다. 지금까지 내가 체크 박스 목록보기를 생성하고 mysql에서 모든 값을 가져 왔지만 체크 된 listview 값을 가져올 수 없다. listview 체크 박스에서 값을 얻는 방법?

main.xml에 내 클래스입니다
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="@+id/testbutton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Submit" />
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@id/testbutton"
android:layout_alignParentTop="true"/>
</RelativeLayout>
내가 testbutton (버튼)에이를 구현 한
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="@+id/cbBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" >
</CheckBox>
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:orientation="vertical"
android:layout_weight="1" >
<TextView
android:id="@+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="2dip"
android:textStyle="bold"/>
</LinearLayout>
</LinearLayout>
result.xml 확인하시기 바랍니다 클릭
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
SparseBooleanArray checked = list1.getCheckedItemPositions();
ArrayList<String> selectedItems = new ArrayList<String>();
for (int i = 0; i < checked.size(); i++) {
int position = checked.keyAt(i);
if (checked.valueAt(i))
selectedItems.add((String) adapter.getItem(position));
}
String[] valuess = new String[selectedItems.size()];
for (int i = 0; i < selectedItems.size(); i++) {
valuess[i] = selectedItems.get(i);
}
Toast.makeText(ListViewMultipleSelectionActivity.this, String.valueOf(valuess), Toast.LENGTH_SHORT).show();
}
});

테스트 버튼의 모든 체크 된 값을 원합니까? –
네, testbutton을 클릭하면, 나는 listview의 모든 값을 확인하고 싶습니다. –
