AlertDialog_深度搜索配合哪个软件

步骤：

AutoCompleteTextView

1、布局中加入AutoCompleteTextView控件，设置好参数（android:completionThreshold是设置从第几开始匹配，默认为2）

2、活动中

1）找到控件

2）设置适配器（同ListView）

3)   设置补全内容（适配器要用）

4）控件绑定适配器

MultiAutoCompleteTextView

前4步同上

5）设置 分隔符（区别）

multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

代码如下：

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.leixiansheng.autotext.MainActivity"> <!--默认第二个字符开始匹配。第一个字符开始匹配：android:completionThreshold="1"--> <AutoCompleteTextView android:id="@+id/auto_text" android:hint="请输入需要匹配内容·····" android:layout_width="match_parent" android:layout_height="wrap_content" /> <MultiAutoCompleteTextView android:id="@+id/mul_text" android:hint="多选择匹配" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@+id/auto_text" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_marginTop="37dp" /> </RelativeLayout> 

package com.example.leixiansheng.autotext; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.AutoCompleteTextView; import android.widget.MultiAutoCompleteTextView; /** * 自动补全 * 步骤： * 1、找到控件 * 2、配置适配器（同ListView） * 3、设置自动补全资源,如data * 4、控件绑定适配器 */ public class MainActivity extends AppCompatActivity { private AutoCompleteTextView autoCompleteTextView; private MultiAutoCompleteTextView multiAutoCompleteTextView; String[] datas = new String[]{"team", "tea", "text", "temp" ,"see","seak","set"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.auto_text); multiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.mul_text); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, datas); autoCompleteTextView.setAdapter(adapter); multiAutoCompleteTextView.setAdapter(adapter); //区别，需要设置分隔符 multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); } } 

SearchView自动搜索

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.v7.widget.SearchView android:id="@+id/search_view" android:layout_width="match_parent" android:layout_height="wrap_content"> </android.support.v7.widget.SearchView> <ListView android:id="@+id/list_view" android:layout_width="match_parent" android:layout_height="wrap_content"> </ListView> </LinearLayout>

package com.leixiansheng.test; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.SearchView; import android.text.TextUtils; import android.util.Log; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast; /** * Created by Leixiansheng on 2017/9/12. */ public class SearchViewActivity extends AppCompatActivity { private static final String TAG = "SearchViewActivity"; private static final String[] contents = {"test", "text", "tea", "teach", "see", "sea", "set", "sell"}; private SearchView searchView; private ListView listView; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_searchview); searchView = (SearchView) findViewById(R.id.search_view); listView = (ListView) findViewById(R.id.list_view); final ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, contents); listView.setAdapter(arrayAdapter); listView.setTextFilterEnabled(true); searchView.setIconifiedByDefault(false); //直接显示搜索框，不隐藏 /** * 搜索监听 * FilterText 内容过滤器 */ searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { @Override public boolean onQueryTextSubmit(String query) { return false; } @Override public boolean onQueryTextChange(String newText) { Log.i(TAG, newText); if (!TextUtils.isEmpty(newText)) { listView.setFilterText(newText); // arrayAdapter.getFilter().filter(newText); } else { listView.clearTextFilter(); } return true; } }); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { Toast.makeText(SearchViewActivity.this, listView.getAdapter().getItem(i).toString(), Toast.LENGTH_SHORT).show(); } }); } }
