Question

您好我想设置听众在Android 2.3中使用appcompat搜索编辑文本。
我的contact_menu.xml是

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:myapp="http://schemas.android.com/apk/res-auto" >

<item
    android:id="@+id/action_search"
    android:orderInCategory="100"
    android:title="@string/action_search"
    myapp:actionViewClass="android.support.v7.widget.SearchView"
    myapp:showAsAction="always"
    android:actionLayout="@layout/actionbar_search"
    />

我的actionbar_search.xml是

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="right"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/search"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10" >

        <requestFocus />
    </EditText>

</LinearLayout>

和我的代码

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.contact_menu, menu);

            View v = (View) menu.findItem(R.id.action_search).getActionView();

            //** Get the edit text from the action view *
            EditText txtSearch = ( EditText ) v.findViewById(R.id.search);

            //** Setting an action listener *
            txtSearch.setOnEditorActionListener(new OnEditorActionListener() {

                @Override
                public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                    Toast.makeText(getBaseContext(), "Search : " + v.getText(), Toast.LENGTH_SHORT).show();
                    return false;
                }
            });

        return true;
    }

问题是当我在android 2.3模拟器中运行它时，我会给出此错误消息

更新
经过@blubrain的一些研究和有用的评论，当然this answer 我达到了这个代码：

我的菜单

<menu xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:sarinaB="http://schemas.android.com/apk/res-auto"  >

    <item
        android:id="@+id/add_item"
        android:icon="@drawable/add"
        android:orderInCategory="100"
        sarinaB:showAsAction="always"/>
    <item
        android:id="@+id/action_search"
         android:icon="@android:drawable/ic_menu_search"
        sarinaB:actionViewClass="android.support.v7.widget.SearchView"
        android:orderInCategory="100"
        android:title="@string/action_search"
        sarinaB:showAsAction="ifRoom"/>

</menu>

我的oncreateoptionmenu

@Override
    public boolean onCreateOptionsMenu(Menu menu) { 
        getMenuInflater().inflate(R.menu.contact_menu, menu); 
        MenuItem searchItem = menu.findItem(R.id.action_search); 
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

        searchView.setOnQueryTextListener(new OnQueryTextListener() {

            @Override
            public boolean onQueryTextSubmit(String text) {
                Toast.makeText(getApplicationContext(), "dddddd "+text, Toast.LENGTH_LONG).show();
                return false;
            }

            @Override
            public boolean onQueryTextChange(String text) {
                Toast.makeText(getApplicationContext(), "sssssss "+text, Toast.LENGTH_LONG).show();
                return false;
            }
        });


    return true;
    }

Answer 1

从Android documentation page引用：

If supporting API levels lower than 11:
- import android.support.v7.app.ActionBar
If supporting only API level 11 and higher:
- import android.app.ActionBar

确保您要导入正确的操作栏，请阅读the document。

其次要确保你正在调用正确的方法。对于2.3，您必须致电

MenuItemCompat.getActionView()

有关进一步说明：请查看this part of the document。

所以行

View v = (View) menu.findItem(R.id.action_search).getActionView();

应该是

View v = (View) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));

使用appcompat访问操作栏中的搜索编辑文本
