For example, our preferences.xml file was added by addPreferencesFromResource (R.xml.preferences). Our preferences.xml file contains such item:
<ListPreference android:id="@+id/order_by" android:key="@string/pref_sort_key" android:title="@string/pref_sort_title" android:summary="@string/pref_sort_summary" android:dialogTitle="@string/pref_sort_dialog_title" android:entries="@array/sort_oder" android:entryValues="@array/sort_oder_value" android:defaultValue="@string/pref_default_sort_value" app:iconSpaceReserved="false" /> In our Fragment, we can dynamically get current notification preference value in this way:
<ListPreference android:id="@+id/order_by" android:key="@string/pref_sort_key" android:title="@string/pref_sort_title" android:summary="@string/pref_sort_summary" android:dialogTitle="@string/pref_sort_dialog_title" android:entries="@array/sort_oder" android:entryValues="@array/sort_oder_value" android:defaultValue="@string/pref_default_sort_value" app:iconSpaceReserved="false" /> In our Fragment, we can dynamically get current notification preference value in this way:

The Testing Pyramid, shown in the Figure, illustrates how your app should include the three categories of tests: small, medium, and large. Medium tests are integration tests that:
正確答案: C
For example, suppose that in a XML file (res/menu/menu_main.xml as an example), where menu items are described, we have such item:
...
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="@string/menu_action_settings"
app:showAsAction="never" />
...
Attribute "app:showAsAction" shows when and how this item should appear as an action item in the app bar. What value "never" in this attribute means?

"Set the activity content to an explicit view. This view is placed directly into the activity's view hierarchy. It can itself be a complex view hierarchy." This can be done by calling method:
正確答案: E
An example. In our ViewModelFactory (that implements ViewModelProvider.Factory) we have an instance of our Repository, named mRepository. Our ViewModel has such constructor:
class MyViewModel(private val mRepository: MyRepository) : ViewModel() ...
Next, in our ViewModelFactory create ViewModel method (overriden) looks like this:
override fun <T : ViewModel?> create(modelClass: Class<T>): T {
return try {
//MISSED RETURN VALUE HERE"
} catch (e: InstantiationException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: IllegalAccessException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: NoSuchMethodException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: InvocationTargetException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
}
}
What should we write instead of "//MISSED RETURN VALUE HERE"?
class MyViewModel(private val mRepository: MyRepository) : ViewModel() ...
