Android ContextMenu和Listview配合使用

@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		ListView listView = (ListView) findViewById(R.id.listView1);
		adapter= new ArrayAdapter<String>(
				getApplicationContext(), android.R.layout.simple_list_item_1,
				getResources().getStringArray(R.array.mylistitem));
		listView.setAdapter(adapter);
		registerForContextMenu(listView); //注册listview的ContextMenu
		super.onResume();
	}
	@Override
	public boolean onContextItemSelected(MenuItem item) {
		// TODO Auto-generated method stub		
		 AdapterContextMenuInfo menuInfo = (AdapterContextMenuInfo)item.getMenuInfo();  //获得AdapterContextMenuInfo,以此来获得选择的listview项目
		 Toast.makeText(getApplicationContext(), adapter.getItem(menuInfo.position)+"", 0).show();
		 
		return super.onContextItemSelected(item);
	}
	@Override
	public void onCreateContextMenu(ContextMenu menu, View v,
			ContextMenuInfo menuInfo) {
		// TODO Auto-generated method stub
		menu.setHeaderTitle("Context Menu");
		menu.add(0, v.getId(), 0, "Action 1");		
		menu.add(0, v.getId(), 0, "Action 2");		
		super.onCreateContextMenu(menu, v, menuInfo);
	}
