Android EditText筛选+选择功能开发

在日常开发中经常会遇到这种需求，EditText既需要可以筛选，又可以点击选择。这里筛选功能用的是AutoCompleteTextView，选择功能使用的是第三方库https://github.com/kongzue/DialogX。

Android AutoCompleteTextView(自动完成文本框)的基本使用

布局文件：activity_main.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context=".MainActivity"><AutoCompleteTextViewandroid:id="@+id/atv_content"android:layout_width="match_parent"android:layout_height="48dp"android:completionHint="请输入搜索内容"android:completionThreshold="1"android:dropDownHorizontalOffset="5dp" /><MultiAutoCompleteTextViewandroid:id="@+id/matv_content"android:layout_width="match_parent"android:layout_height="48dp"android:completionThreshold="1"android:dropDownHorizontalOffset="5dp"android:text="" /></LinearLayout>

MainActivity.java：

public class MainActivity extends AppCompatActivity {private AutoCompleteTextView atv_content;private MultiAutoCompleteTextView matv_content;private static final String[] data = new String[]{"小猪猪", "小狗狗", "小鸡鸡", "小猫猫", "小咪咪"};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);atv_content = (AutoCompleteTextView) findViewById(R.id.atv_content);matv_content = (MultiAutoCompleteTextView) findViewById(R.id.matv_content);ArrayAdapter<String> adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_dropdown_item_1line, data);atv_content.setAdapter(adapter);ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_dropdown_item_1line, data);matv_content.setAdapter(adapter);matv_content.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());}
