Android Custom ListView With CheckBox Example.

This example will show you how to add a checkbox to each android listview item. It also demonstrates how to select all, deselect all, reverse select and remove selected listview items programmatically.

1. Android ListView With CheckBox Example.

Below is this example demo video ( select all none reverse and delete selected list view items example ).

There are four Java classes, one main layout XML file, and one list view item layout XML file in the above example.

I’m trying to build up this example and am stuck in the xml file
where it says ‘Namespace prefix Android is not defined’. (Using Visual Studio 2019)

eyie

I am trying to get the clicked items by updating the initItemList checkbox, but when the process is entering the delete button, the initItemList checked variable is not updated to “true.”

I had to set the clickable and focusable property of the checkbox in the row.xml to “true,” otherwise the UI is not clickable.

Thanks.

paul kiing

Process: com.example.checkbox, PID: 28511

Please see the method

// When list view item is clicked.
listViewWithCheckbox.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView adapterView, View view, int itemIndex, long l)

in ListViewWithCheckboxActivity.java

Ray

hey,

it seems I cannot resolve symbol widget.recycler, thus “extends recycler.viewholder” won’t work; I am new to all of this, could you please help me solve this?

Reply to Ray

What error message can you get?

Sasa

add implementation ‘com.android.support:recyclerview-v7:26.1.0’
or higher version to your build.grade 🙂
