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">

    <AutoCompleteTextView
        android: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" />

    <MultiAutoCompleteTextView
        android: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"
    };

    @Override
    protected 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());
    }
}
