代码SearchActivity.java

package com.jialianjia.bzw.activity;

import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.annotation.SuppressLint;
import android.widget.ListView;
import android.widget.SearchView;
import com.jialianjia.bzw.BaseActivity;
import com.jialianjia.bzw.R;
import com.lidroid.xutils.ViewUtils;
import java.util.ArrayList;

/**
* 搜索
* Created by Gxs on 2016/5/5.
*/

public class SearchActivity extends BaseActivity implements SearchView.OnQueryTextListener{

private SearchView searchView;
private ListView listView;
private ArrayAdapter<String> arrayAdapter;
private ArrayList<String> arrayList = new ArrayList<String>();
private Object[] names;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
names = loadData();
ViewUtils.inject(this);
searchView = (SearchView) findViewById(R.id.searchView);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(new ArrayAdapter<Object>(getApplicationContext(),
 android.R.layout.simple_expandable_list_item_1, names));
searchView.setOnQueryTextListener(this);
searchView.setSubmitButtonEnabled(false);
}
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}

@Override
public boolean onQueryTextChange(String newText) {
Object[] obj = searchItem(newText);
updateLayout(obj);
return false;
}

public Object[] searchItem(String name) {
ArrayList<String> mSearchList = new ArrayList<String>();
for (int i = 0; i < arrayList.size(); i++) {
 int index = arrayList.get(i).indexOf(name);
 // 存在匹配的数据
 if (index != -1) {
 mSearchList.add(arrayList.get(i));
 }
}
return mSearchList.toArray();
}

// 更新数据
public void updateLayout(Object[] obj) {
listView.setAdapter(new ArrayAdapter<Object>(getApplicationContext(),
 android.R.layout.simple_expandable_list_item_1, obj));
}

// 测试数据
public Object[] loadData() {
arrayList.add("aaa");
arrayList.add("aab");
arrayList.add("aac");
arrayList.add("aad");
arrayList.add("abc");
arrayList.add("abcd");
arrayList.add("cdf");
arrayList.add("eda");
arrayList.add("sdfa");
arrayList.add("ddda");
arrayList.add("sssa");
return arrayList.toArray();
}
}
