Не може да се създаде клас android.support.v7.widget.SearchView

Моля, някой да ми помогне! Опитвам се да добавя изглед за търсене на appcompat към моя проект. Неуспешно. Когато променя android.support.v7.widget.SearchView на SearchView (API > 10), всичко е наред.

Това е моето меню:

<item android:id="@+id/action_search"
    android:title="@string/search_view_title"
    android:icon="@drawable/action_search"
    sabd:showAsAction="always|collapseActionView"
    sabd:actionViewClass="android.support.v7.widget.SearchView" />

Ето как се опитвам да използвам SearchView:

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.teach, menu);
        mSearchItem = menu.findItem(R.id.action_search);
        mSearchItem.setVisible(true);
        mSearchView = (SearchView) MenuItemCompat.getActionView(mSearchItem);
        mSearchView.setQueryHint(getString(R.string.search_view_hint));
        mSearchView.setOnQueryTextListener(this);
    }

Това е моят манифестен файл:

Вероятно имах подобно, което се появи на компилациите ми за издание, но не и компилациите ми за отстраняване на грешки при превключване към библиотеката за поддръжка v21. Оказа се проблем с обфускацията и добавянето на този ред към моя proguard-rules.txt файл го поправи:

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

къде трябва да добавя този ред? - person Solace; 25.12.2014

Ако използвате proroguard, тогава трябва да добавите във вашия файл с правила на proguard. Ако не използвате proguard, това не решава проблема ви. - person jgnt32; 15.07.2015

Имах същия проблем, когато използвах Android Studio и Gradle, за да създам моя проект. Бих искал да добавя SearchView на v7 compat.

Решението е да промените версията на приставката gradle от 0.9.1 или други на 0.9.0. Това е временен начин, който намерих. Това може би е грешка на плъгина gradle. Надявам се това да помогне.

    dependencies {
        classpath "com.android.tools.build:gradle:0.9.0"
    }

Благодаря ви за отговора, но използвам Eclipse с Ant. - person jgnt32; 10.04.2014

Проблемът беше в лоша библиотека за поддръжка на v7. След актуализация всичко е наред.

Изглежда, че сега го има отново, нали? Получавам го на Android L на Nexus 7 от един от крайните потребители. - person android developer; 29.10.2014

Да, изглежда, че проблемът се е върнал с актуализация 5.0 на библиотеката за поддръжка - person AAverin; 31.10.2014

Опитайте да добавите това към вашия proguard: -keep class android.support.v7.widget.SearchView { *; } Справка: stackoverflow.com/questions/23413938/ - person LyteSpeed; 04.11.2014

Не правя никакво объркване и продължавам да получавам проблема в режим на отстраняване на грешки - person AAverin; 05.11.2014
