Android AppCompat v21中的SearchView出现问题

我正在Android Studio 0.8.14中使用带工具栏和im的AppCompat v21

如果我通过usb将我的（4.4）手机插入PC并运行应用程序，searchview将正常工作。我打开片段并按下搜索图标，它允许我键入文本

然而，如果我在gradle中组装发布版，并在按下搜索图标时在设备上安装应用程序，则不会发生任何事情。不会启动searchview。这是我的密码

我的IconsFrag.java

@Override
public void onPrepareOptionsMenu (Menu menu) {
    Log.i(FRAG_TAG, "onPrepareOptionsMenu");
    MenuInflater inflater = getActivity().getMenuInflater();
    inflater.inflate(R.menu.icon_menu, menu);
    MenuItem searchItem = menu.findItem(R.id.search);

    SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView = null;
    if (searchItem != null) {
        searchView = (SearchView) searchItem.getActionView();
    }
    if (searchView != null) {
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
    }

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    Log.i(FRAG_TAG, "onOptionsItemSelected");
    return super.onOptionsItemSelected(item);
}

我的模块build.gradle

Properties props = new Properties()
props.load(new FileInputStream(file(project.property("test.properties"))))

android {

这是我的菜单

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/search"
        android:title="@string/search"
        android:icon="@drawable/app_ic_menu_search"
        app:showAsAction="always"
        app:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

可能是proguard重命名了

SearchView

类。尝试将其添加到您的

proguard.txt

文件中

-keep class android.support.v7.** { *; }

这么简单。非常感谢您小心：这将保留所有appcompat-v7，即使是您不使用的东西！
