Question #11 (Topic: Single Topic)
For example, our preferences.xml file was added by addPreferencesFromResource(R.xml.preferences). Our preferences.xml file contains such
item:
<SwitchPreference
android:id="@+id/notification"
android:key="@string/pref_notification_key"
android:title="@string/pref_notification_title"
android:summary="@string/pref_notification_summary"
android:defaultValue="@bool/pref_notification_default_value"
app:iconSpaceReserved="false"/>
In our Fragment, we can dynamically get current notification preference value in this way:
item:
<SwitchPreference
android:id="@+id/notification"
android:key="@string/pref_notification_key"
android:title="@string/pref_notification_title"
android:summary="@string/pref_notification_summary"
android:defaultValue="@bool/pref_notification_default_value"
app:iconSpaceReserved="false"/>
In our Fragment, we can dynamically get current notification preference value in this way:
A. val isNotificationOn = PreferenceManager.getDefaultSharedPreferences(context).getBoolean( context!!.getString(R.string.pref_notification_key), context!!.resources.getBoolean(R.bool.pref_notification_default_value) )
B. val isNotificationOn = PreferenceManager.getSharedPreferences(context).getBoolean( context!!.getString(R.string.pref_notification_default_value), context!!.getString(R.string.pref_notification_key), )
C. val isNotificationOn = PreferenceManager.getSharedPreferences(context).getBoolean( context!!.resources.getBoolean(R.bool.pref_notification_default_value), context!!.getString(R.string.pref_notification_key) )
Answer: A
Question #12 (Topic: Single Topic)
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:
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:
A. val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(R.string.pref_sort_key), context!!.resources.getBoolean(R.bool.pref_default_sort_value) )
B. val sortBy = PreferenceManager.getSharedPreferences(context).getString( context!!.getString(R.string.pref_default_sort_value), context!!.getString(R.string.pref_sort_key), )
C. val sortBy = PreferenceManager.getSharedPreferences(context).getBoolean( context!!.resources.getBoolean(R.bool.pref_default_sort_value), context!!.getString(R.string.pref_sort_key) )
D. val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(R.string.pref_sort_key), context!!.getString(R.string.pref_default_sort_value) )
Answer: D
Question #13 (Topic: Single Topic)
For example, we have a file in our raw folder app/src/main/res/raw/sample_teas.json. To get an InputStream for reading it, from out Context
context, we can do this:
context, we can do this:
A. val input = context!!.openRawResource(R.raw.sample_teas)
B. val input = context!!.getRawResource(R.raw.sample_teas)
C. val input = context!!.resources.openRawResource(R.raw.sample_teas)
Answer: C
Question #14 (Topic: Single Topic)
For example, we have a BufferedReader reader, associated with the json file through InputStreamReader. To get a file data we can do this:
A. var line: String? try { while (reader.readLine().also { line = it } != null) { builder.append(line) } val json = JSONObject(builder.toString()) return json } catch (exception: IOException) { exception.printStackTrace() } catch (exception: JSONException) { exception.printStackTrace() }
B. var line: JSONObject ? try { while (reader.readJSONObject ().also { line = it } != null) { builder.append(line) } val json = JSONObject(builder.toString()) return json } catch (exception: IOException) { exception.printStackTrace() } catch (exception: JSONException) { exception.printStackTrace() }
C. var line: String? try { while (reader.readLine().also { line = it } != null) { builder.append(line) } val json = JSONObject(builder.toString()) return json } catch (exception: RuntimeException) { exception.printStackTrace() } catch (exception: ArrayIndexOutOfBoundsException) { exception.printStackTrace() }
Answer: A
Question #15 (Topic: Single Topic)
For example, we have a file in our assets folder app/src/main/assets/sample_teas.json. To get an InputStream for reading it, from out Context
context, we can try do this:
context, we can try do this:
A. val input = context!!.resources.openRawResource(R.raw.sample_teas)
B. val input = context!!.assets.open("sample_teas.json")
C. val input = context!!.resources.assets.open("sample_teas.json")
Answer: B
