	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		autoCompleteTextView1=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
		autoCompleteTextView1.setText("");
		adapter=new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_dropdown_item_1line,nameStrings);
		autoCompleteTextView1.setAdapter(adapter);
		autoCompleteTextView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
			public void onItemClick(AdapterView<?> parent, View view, int position, long arg3){
				String nameString=parent.getItemAtPosition(position).toString();
				showToast(nameString);
			}
		});
	}
	private void showToast(CharSequence msg) {
		Toast.makeText(this, msg, Toast.LENGTH_SHORT).show();
	}
	

	@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;
	}

}
