1，導(dǎo)入一下design的依賴

2，布局文件很簡單，只有兩個控件
注意：android:iconifiedByDefault 里面最好為 false
讓搜索框默認(rèn)就展開設(shè)置setIconifiedByDefault(false)即可

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical"
  tools:context="zlw.com.searcohview.MainActivity">
<SearchView
  android:id="@+id/main_searchview"
  android:queryHint="請輸入搜索內(nèi)容"
  android:iconifiedByDefault="false"
  android:layout_width="match_parent"
  android:layout_height="wrap_content">
</SearchView>
<ListView
android:id="@+id/main_listview"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ListView>
</LinearLayout>

3，代碼部分

   package zlw.com.searcohview;
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   import android.text.TextUtils;
   import android.widget.ArrayAdapter;
   import android.widget.ListView;
   import android.widget.SearchView;
   public class MainActivity extends AppCompatActivity {
   private String[] searcoh = {"hhhhh","cccccc","wwwwww","ddddd","aaaaa"};
   private SearchView main_searchview;
   private ListView main_listview;
   @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    findViews();
}
private void findViews() {
    main_searchview = (SearchView) findViewById(R.id.main_searchview);
    main_listview = (ListView) findViewById(R.id.main_listview);
    main_listview.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, searcoh));
    main_listview.setTextFilterEnabled(true);
    main_searchview.setOnQueryTextListener(new SearchView.OnQueryTextListener() // 設(shè)置搜索文本監(jiān)聽{
        @Override
        public boolean onQueryTextSubmit(String query) {//搜索時觸發(fā)事件
            return false;
        }
        @Override
        public boolean onQueryTextChange(String newText) {//搜索時根據(jù)文本框動態(tài)改變搜索內(nèi)容
            if (!TextUtils.isEmpty(newText)){
                main_listview.setFilterText(newText);
            }   else {
                main_listview.clearChoices();
            }
            return false;
        }
    });
}
}
