Android仿QQ输入法词根联想AutoCompleteTextView及多提示项群发邮件分隔录入MultiAutoCompleteTextView

怎么这么长，看着这么高大上呢。。

其实就是这个效果

这里写图片描述

显示的内容都是词根。。

  private static final String[] data = new String[]{
            "小猪猪", "小狗狗", "小鸡鸡", "小猫猫", "小咪咪"
    };

不多说了，我们来贴代码吧

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">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="AutoCompleteTextView(自动完成文本框)"/>
    <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" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MultiAutoCompleteTextView(多提示项的自动完成文本框)"/>
    <MultiAutoCompleteTextView
        android:id="@+id/matv_content"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:completionThreshold="1"
        android:dropDownHorizontalOffset="5dp"
        android:text="" />

</LinearLayout>

展示视图控制文件：MainActivity

public class MainActivity extends AppCompatActivity {

    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());
    }
}
