Android - 在操作栏中具有自动完成功能的搜索视图 [英] Android - searchview with auto complete feature inside action bar

问题描述

我想构建一个包含 Sherlock 操作栏和搜索视图的应用程序.但是，我希望这个搜索视图具有像 autocompleteTextView 那样的自动完成功能.是否有任何直接的实现可以单独使用 searchview 来做到这一点?还是应该在操作栏中使用 autocompleteTextView 来执行此操作?我在那里找到了几个帖子，但没有一个对我有帮助.这些帖子仅讨论创建 autocompleteTextView ，但我希望搜索视图具有此功能.知道怎么做吗?

I want to build an app that has sherlock action bar and a search view inside it. However, i want this searchview to have autocomplete feature like what autocompleteTextView has. Is there any straight forward implementation to do that using searchview alone? or should i use autocompleteTextView inside action bar to do this? I found several posts out there, but none of them are helping me. Those posts talk only about creating a autocompleteTextView , but i want search view to have this functionality. Any idea how can it be done?

推荐答案

为此，我使用 AutoCompleteTextView 创建一个布局并将其添加到 ActionBar 调用 ActionBar 中的自定义布局.

For this I have Create one Layout with AutoCompleteTextView and add it in ActionBar its call Custom layout in ActionBar.

之后，我使用 android.R.layout.simple_dropdown_item_1line 创建了适配器.在 AutoCompleteTextView 中设置.

After that I have Create Adapter with android.R.layout.simple_dropdown_item_1line. set it in AutoCompleteTextView.

检查下面的代码:

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);

    }

}

您的布局:

<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>
