How to add a checkbox in the list?

Question

I have a question that got stuck for a while, I don’t know how to add an item to the list, for example, if I have a list of items that I want to check. my xml code is as follows:

<LinearLayout android:id="@+id/topLayout"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_centerHorizontal="true"  android:layout_height="wrap_content">

</LinearLayout>

<LinearLayout
    android:id="@+id/middleLayout"
    android:orientation="horizontal"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent">

    <LinearLayout android:id="@+id/leftMiddleLayout"
            android:orientation="vertical" android:layout_below="@+id/topLayout"
            android:layout_above="@+id/bottomLayout"
            android:layout_width="60px" android:layout_height="wrap_content"
            >

            <ListView android:id="@+id/checkboxList" android:layout_width="fill_parent"
                    android:layout_height="wrap_content" ></ListView>

            <CheckBox android:id="@+id/checkbox"
            android:layout_width="wrap_content" android:layout_height="wrap_content"
            android:checked="false"
            android:text="test">
            </CheckBox>

    </LinearLayout>

    <LinearLayout android:id="@+id/rightMiddleLayout"
            android:orientation="vertical" android:layout_below="@+id/topLayout"
            android:layout_above="@+id/bottomLayout"
            android:layout_width="280px" android:layout_height="wrap_content"
            >

            <ListView android:id="@+id/list" android:layout_width="fill_parent"
                    android:layout_height="wrap_content" ></ListView>

            <TextView android:id="@+id/text" android:layout_width="fill_parent"
                    android:layout_height="wrap_content"/>                   
    </LinearLayout>
</LinearLayout>

<LinearLayout android:id="@+id/bottomLayout" 
    android:layout_alignParentBottom="true" 
    android:orientation="horizontal" 
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:paddingBottom="5pt"
    >

    <EditText android:id="@+id/insertNewItem"
        android:layout_width="220px" android:layout_height="wrap_content" />

    <TextView android:layout_width="10px" android:layout_height="wrap_content" />

    <Button android:id="@+id/addItemButton" android:layout_width="wrap_content"
        android:layout_height="fill_parent" android:text="Add Item"/>
</LinearLayout>

If you have ideas, please let me know for my academic studies: ((

public class myAdapter extends SimpleCursorAdapter {
    public myAdapter(Context context, int layout, Cursor cursor, String[] from, int[] to) {
        super(context, layout, cursor, from, to);  
}

@Override   
public void bindView(View view, Context context, Cursor cursor) {
    cb=(CheckBox)view.findViewById(R.id.cb);
    cb.setText(dbgetStringValue);
    cbText=(TextView)view.findViewById(R.id.cbText);
            cbText.setText(dbgetStringValue);
    cb.setChecked(false);
    cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton cb, boolean isChecked) {            
            if(cb.isChecked()) {                    
                // action
            }
            else if(isChecked==false) {
                // action
            }
        }           
    });
}
} 

- Is this what you want?

Answer 2

final ListView lView = (ListView) findViewById(R.id.ListView01);
lView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, items));
lView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

Here the element is an array.

Answer 4

If you use a ListAdapter (e.g. a customized BaseAdapter) in your View list using setAdapter (), you can use the LayoutInflater inside your getView () adapter to provide any layout you like for your entries in the list. This may include a CheckBox.

Answer 5

Or you can extend any ListAdapter to a subclass and override bindView. Inside if you installed .setText for ChecBoxes!
