Main Activity
package com.example.creating_listview; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.view.Menu; import android.view.View; import android.widget.Button; public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub startActivity(new Intent("com.example.creating_listview.list")); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); finish(); } }
List
package com.example.creating_listview; import android.app.ListActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; public class list extends ListActivity { String list_item[] = { "MainActivity", "FirstActivity", "SecondActivity" }; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, list_item)); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { // TODO Auto-generated method stub super.onListItemClick(l, v, position, id); String open_class = list_item[position]; try{ Class selected = Class.forName("com.example.creating_listview."+open_class); Intent selected_activity = new Intent(this,selected); startActivity(selected_activity); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally{ } } }
