Android Listview Example/Tutorial – Coderz Passion

To create Listview we need the following:-

MainActivity class containing  Listview will be the main screen.

MainActivity.java

package com.androidruler.simplelistview;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.ListView;

import java.util.ArrayList;




public class MainActivity extends AppCompatActivity {




    ListView mainactivity;

    // creating arraylist of MyItem type to set to adapter

    ArrayList<String> myitems=new ArrayList<>();




    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        mainactivity=(ListView)findViewById(R.id.mainactivitylistview);

   //Adding data to arraylist to be passed to ArrayAdapter. u can use arrays also.

         myitems.add("Christ Redeemer: Rio de Janeiro Brazil"));

         myitems.add("Great Wall of China: China");

         myitems.add("Machu Picchu: Peru");

         myitems.add("Petra: Jordan");

         myitems.add("Pyramid at Chichén Itzá:YucataPeninsula, Mexico");

         myitems.add("Roman Colosseum: Rome, Italy");

         myitems.add("Taj Mahal: Agra, India");







        //Creating Adapter object for setting to listview

        ArrayAdapter adapter=new ArrayAdapter<String>        (MainActivity.this,android.R.layout.simple_list_item_1,android.R.id.text1,myitems);

        mainactivity.setAdapter(adapter);

      }

 @Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

//getMenuInflater().inflate(R.menu.menu_main, menu);

//this shows three d ots at right corner on click settings open return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

 // Handle action bar item clicks here. The action bar will

 // automatically handle clicks on the Home/Up button, so long

// as you specify a parent activity in AndroidManifest.xml.

int id = item.getItemId();

//noinspection SimplifiableIfStatement if (id == R.id.action_settings)

{

return true;

}

return super.onOptionsItemSelected(item);

 }

 }

//layout file for MainActivity.java

activity_main.xml

<RelativeLayout

    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

        android:layout_height="fill_parent"

        android:divider="@android:color/black"

        android:dividerHeight="2dp"></ListView>
