Main activity

package saro.example.com.task2_listview;

import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;

import android.widget.ListView;
import android.widget.ListAdapter;
import android.widget.PopupWindow;
import android.widget.TextView;
import android.content.Context;
import android.widget.Toast;
import android.widget.PopupMenu;

public class MainActivity extends AppCompatActivity {
ListView list;
@Override
protected void onCreate(final Bundle savedInstanceState) {
String[] mobileArray = {"Android", "IPhone", "WindowsMobile", "Blackberry",
"WebOS", "Ubuntu", "Windows7", "Max OS X"};

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

ArrayAdapter adapter = new ArrayAdapter<string>(this,
R.layout.activity_listview, mobileArray);

list = (ListView) findViewById(R.id.mobile_list);
list.setAdapter(adapter);

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Toast.makeText(getApplicationContext(), "Hello Javatpoint", Toast.LENGTH_SHORT).show();
PopupMenu popup = new PopupMenu(MainActivity.this, list);
popup.getMenuInflater()
.inflate(R.menu.popup_menu, popup.getMenu());
}
});
}

}
