Android, click on checkbox in my list doesn't affect onListItemClick() method?

Question

In my application, I have a list. This list includes some texts and a checkbox. In Xml definition of list, If I put android:focusable="true" then I can click it and change it's status from checked to not checked and vice versa. But I can't change its status when I click on its row.

If I put android:focusable="false" the story will exchange. If I choose row, I can change the status of checkbox while if I click on it, nothing will change. I need regardless of clicking on row or checkbox, status of chackbox changes. If i click on checkbox it's status will change but my list doesn't aware of this changes therefore, onListItemClick() not execute.

I tried to add another element android:enabled="false". But UI is not user friendly. Also, when I click on checkbox its status is not changed.

What is your suggestion?

This is xml code of list:

    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <RelativeLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="fill_parent"
            android:layout_height="?android:attr/listPreferredItemHeight"
            android:padding="6dip" >

            <CheckBox 
                android:id="@+id/checkbox"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_alignParentTop="true"
                android:layout_alignParentBottom="true"
                android:layout_marginRight="6dip"
                android:layout_marginLeft="4px"
                android:focusable="false" />

.
.
.

and in code: Flag and planId are String Array.

private String[] flag = new String[50];
private String[] planId = new String[50];

@Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Log.i("List Clicked:", "******");

        //Toggle CheckBox from not selected to selected and vice versa.
        if(flag[position] == "true")
            flag[position] = "false";
        else
            flag[position] = "true";

        //Keep this CheckBox selected and clear the rest.
        for(int i=0; i<position; i++)
            flag[i] = "false";
        for(int i=position+1; i<flag.length; i++)
            flag[i] = "false";

        //If checkBox is selected show dialog if cleared don't show
        if(flag[position] == "true")
            //alertDialog.show();
            dialog.show();

        //Extracting Plan Id
        subscriptionPlanId = planId[position];
    }

Answer 1

Sorry I answer my question here because above is so messy and confusable. For future reference I put my answer here.

Question: When I click on checkbox in a list, its status will change but onListItemClick() method, doesn't aware of this change and therefore this method will not run.

Answer: In XML elemnts of checkbox, just set clickable of this item to false. :) the problem is solved. In my case the XML is:

<Check
android:id="@+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_marginRight="6dip"
android:layout_marginLeft="4px"
android:focusable="false"
android:clickable="false" />

Now, regardless of clicking on row or checkbox, onListItemClick() method will call.

Answer 2

You need to write code to check or uncheck the checkbox by using (checkbox.setChecked()) in onListItemClick method

your code for onListItemClick will be some thing like following

@Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        // super.onListItemClick(l, v, position, id);
        RelativeLayout rl = (RelativeLayout) v;
        for (int i = 0; i < rl.getChildCount(); i++) {
            if ((rl.getChildAt(i)) instanceof CheckBox) {
                CheckBox cb = (CheckBox) rl.getChildAt(i);
                boolean check = cb.isChecked();
                cb.setChecked(!check);
                break;
            }
        }
//      System.out.println(rl.getChildCount() + "...v..." + rl + "...." + id);
        // boolean check = cb.isChecked();
        // cb.setChecked(!check);
    }
