Android - 具有自动完成功能的searchview内部操作栏

Question

我想构建一个具有sherlock操作栏和搜索视图的应用程序.但是,我希望此searchview具有autocompleteTextView具有的自动完成功能.是否有单独使用searchview的直接实现？或者我应该在操作栏内使用autocompleteTextView来执行此操作？我找到了几个帖子,但没有一个人在帮助我.这些帖子只讨论创建autocompleteTextView,但我希望搜索视图具有此功能.知道怎么办？

为此,我创建了一个布局,AutoCompleteTextView并在ActionBar其调用中添加它Custom layout in ActionBar.

之后我创建了适配器android.R.layout.simple_dropdown_item_1line.设置它AutoCompleteTextView.

检查以下代码:

package com.example.testapp;

import android.annotation.TargetApi;
import android.app.ActionBar;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

@TargetApi(11)
public class MainActivity extends Activity {

    private static final String[] COUNTRIES = new String[] { "Belgium",
            "France", "France_", "Italy", "Germany", "Spain" };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ActionBar actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setDisplayShowCustomEnabled(true);
        // actionBar.setDisplayShowTitleEnabled(false);
        // actionBar.setIcon(R.drawable.ic_action_search);

        LayoutInflater inflator = (LayoutInflater) this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View v = inflator.inflate(R.layout.actionbar, null);

        actionBar.setCustomView(v);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_dropdown_item_1line, COUNTRIES);
        AutoCompleteTextView textView = (AutoCompleteTextView) v
                .findViewById(R.id.editText1);
        textView.setAdapter(adapter);

    }

}

你的布局:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Action Bar:"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="#FFFFFF" />

    <AutoCompleteTextView
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ems="10"
        android:imeOptions="actionSearch"
        android:inputType="textAutoComplete|textAutoCorrect"
        android:textColor="#FFFFFF" >

        <requestFocus />
    </AutoCompleteTextView>

</LinearLayout>
