MainActivity代码

package com.example.listviewsingle;

import android.app.Activity;
import android.os.Bundle;
import android.util.SparseBooleanArray;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		final ListView lv = (ListView) findViewById(R.id.lv);

		final String[] data = { "篮球", "足球", "棒球", "乒乓球", "橄榄球", "冰球", "排球", "水球", "其他" };
		ArrayAdapter<String> adapter = new ArrayAdapter<String>(getApplicationContext(),
				android.R.layout.simple_list_item_multiple_choice, data);

		lv.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
				TextView like = (TextView) findViewById(R.id.like);

				SparseBooleanArray sparseBooleanArray = lv.getCheckedItemPositions();
				StringBuffer sb = new StringBuffer();
				;
				for (int i = 0; i < sparseBooleanArray.size(); i++) {
					System.out.println(sparseBooleanArray.get(i));
					if (sparseBooleanArray.valueAt(i)) {

						sb.append(data[sparseBooleanArray.keyAt(i)]).append(",");
					}
				}
				if (sb.length() > 0) {
					String result = sb.substring(0, sb.length() - 1);
					like.setText(result);
				}
				
			}
		});

		lv.setAdapter(adapter);
		lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
	}
