导入 pinyin。jar包

1.在activity_main中定义 listview 并设置id，在MainActivity中找到Listview，然后再定义一个adapter，给Listview设置适配器。

2.然后定义一个拼音类，得到一个字符串的拼音读音，将汉字拆分成一个个的char，

char[] chars = chineseStr.toCharArray();

遍历汉字的每一个char，汉字的所有读音放在一个pinyins数组，PinyinHelper.toHanyuPinyinStringArray()

3.在给他设置默认的输出格式，HanyuPinyinOutputFormat

setToneType:去除声调

setCaseType小写

setVCharType包含Unicode特殊字符

4.定义一个排序的方法implementsComparator<Address>，重写compare方法

5.在MainActivity中Collections.sort(addressList,newSort.AddressCompartor());

代码：

MainActivity：import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.widget.ListView;import java.util.Collections;import java.util.List;public class MainActivity extends AppCompatActivity {    private ListView mListview;    private AddressAdapter adapter;    private List<Address> addressList;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mListview = (ListView) findViewById(R.id.mListView);        addressList = Address.getAddress();        Collections.sort(addressList,new Sort.AddressCompartor());        adapter = new AddressAdapter(this, addressList);        mListview.setAdapter(adapter);    }}
