问题
I am binding Checkbox
using Custom ListView
. Now, at the last, I want all the values of checked CheckBox
.
How to get this ? I want to know that how can I get values using my code. ListView itemOnClickListener
is not firing here.
My code :
Map<String, String> m = null;
for (int i = 0; i < lList.size(); i++) {
objSubCatData = lList.get(i);
lstSubCatId.add(objSubCatData.getSubCatId());
m = new HashMap<String, String>();
m.put("SubCatName", objSubCatData.getSubCatName());
aaSubCategory.add(m);
}
final SimpleAdapter adapter = new SimpleAdapter(UserInterest.this, aaSubCategory, R.layout.userinterest_1, new String[] { "SubCatName" }, new int[] { R.id.chkUserInterest });
lvUserInterest.setAdapter(adapter);
layout1.xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/datalist"
android:orientation="vertical" >
<CheckBox
android:id="@+id/chkUserInterest"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@color/blue"
android:textSize="14sp" >
</CheckBox>
</LinearLayout>
Layout2.xml :
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView
android:id="@+id/lvUserInterest"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="8dp"
android:divider="#b5b5b5"
android:dividerHeight="1dp" />
<Button
android:id="@+id/btnUTSubmit"
android:layout_width="130dp"
android:layout_height="35dp"
android:layout_gravity="center"
android:layout_marginTop="6dp"
android:background="@drawable/blue_bg"
android:text="@string/Submit"
android:textColor="@color/white" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:text="@string/userinterest"
android:textColor="@color/gray" />
</LinearLayout>
回答1:
try this :
first of all you have to set listview to multiple choice like this :
lvUserInterest.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
SparseBooleanArray checked = lvUserInterest.getCheckedItemPositions();
for (int i = 0; i < lvUserInterest.getAdapter().getCount(); i++) {
if (checked.get(i)) {
// Do something
}
}
get your checked values in if condition where you can get checked item...

If your using onClickListner
in customAdapter the onitemClickListner
will not work. i answered question because i can't comment because of repulation
public class CustomListAdapter extends BaseAdapter {
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater=null;
public CustomListAdapter (Activity a, ArrayList<HashMap<String, String>> d) {
activity = a;
data=d;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.layout1, null);
Checkbox Checkeditem= (Checkbox )vi.findViewById(R.id.checkitem);
HashMap<String, String> listitem = new HashMap<String, String>();
listitem = data.get(position);
// Setting all values in listview
Checkeditem.setText(listitem .get(MainActivity.strTagDate));
return vi;
}}
In your MainActivityCustomListAdapter adapter = new CustomListAdapter (Mainactivity.this, aaSubCategory); lvUserInterest.setAdapter(adapter);
