Show or hide widget in ListView when Checkbox is checked or unchecked example in Android

Show or hide a widget in ListView

In this tutorial we will learn how to show or hide a widget in listview when checkbox is checked or unchecked with a simple example in Android Studio.

In this example we will have a  TextView, CheckBox and Spinner in a listview cell. When checkbox is checked the spinner will disable and when it is unchecked the spinner will enable.

Example:

• Create a new project in Android Studio and name it as ListView.
• In activity main.xml copy and paste the following code.

File: activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        
    </ListView>

</RelativeLayout> 

</RelativeLayout> 

• Create a new xml file in layout directory and name it as my_cell for listview cell.
• Copy and paste the following code in my_cell.xml file.

File: my_cell.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="80dp"
    android:gravity="center"
    android:orientation="horizontal"
    android:weightSum="2">

    <TextView
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:textStyle="bold"
        android:textColor="@color/colorAccent"
        android:text="TextView" />

    <CheckBox
        android:id="@+id/checkbox"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.6"
        android:text="Check" />

    <Spinner
        android:id="@+id/spinner"
        android:layout_width="0dp"
        android:layout_height="50dp"
        android:layout_weight="0.4">

    </Spinner>

</LinearLayout>

Now its time to code, Copy and paste the following code in main java file.

File: MainActivity.java:

import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.ListView;
import android.widget.Spinner;
import android.widget.TextView;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    ListView listview;
    MyAdapter myAdapter;
    ArrayList<String> myValues = new ArrayList<String>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listview = (ListView) findViewById(R.id.listView);

        // adding array items for listview
        myValues.add("Android Lovers");
        myValues.add("Cupcake");
        myValues.add("Donut");
        myValues.add("Eclair");
        myValues.add("Froyo");
        myValues.add("Gingerbread");
        myValues.add("Honeycomb");
        myValues.add("IceCream Sandwich");
        myValues.add("Jelly Bean");
        myValues.add("Lollipop");
        myValues.add("Marshmallow");

        myAdapter = new MyAdapter();

        //  set adapter for listview
        listview.setAdapter(myAdapter);
    }


    //  Custom adapter for listview
    class MyAdapter extends BaseAdapter {
        //  spinner items
        String[] spinnerValues = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10"};

        @Override
        public int getCount() {
            return myValues.size();
        }

        @Override
        public Object getItem(int arg0) {
            return myValues.get(arg0);
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) MainActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View myView = convertView;
            if (convertView == null)
                myView = inflater.inflate(R.layout.my_cell, null);
            TextView names = (TextView) myView.findViewById(R.id.textView);

            final CheckBox checkBox = (CheckBox) myView.findViewById(R.id.checkbox);
            final Spinner spinner = (Spinner) myView.findViewById(R.id.spinner);

            names.setText(myValues.get(position));

            //  set adapter for spinner
            final ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, spinnerValues);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            spinner.setAdapter(adapter);

            checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                    CheckBox checkBox = (CheckBox) compoundButton.findViewById(R.id.checkbox);
                    if (checkBox.isChecked()) {
                        spinner.setEnabled(false);
                        myAdapter.notifyDataSetChanged();
                    } else {
                        spinner.setEnabled(true);
                        myAdapter.notifyDataSetChanged();
                    }
                }
            });

            return myView;
        }

    }

}
