QUESTION: 11 Topic: KOTLIN only

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:

val isNotificationOn = PreferenceManager.getDefaultSharedPreferences(context).getBoolean(
context!!.getString(R.string.pref_notification_key),
context!!.resources.getBoolean(R.bool.pref_notification_default_value)
)
val isNotificationOn = PreferenceManager.getSharedPreferences(context).getBoolean(
context!!.getString(R.string.pref_notification_default_value),
context!!.getString(R.string.pref_notification_key),
)
val isNotificationOn = PreferenceManager.getSharedPreferences(context).getBoolean(
context!!.resources.getBoolean(R.bool.pref_notification_default_value),
context!!.getString(R.string.pref_notification_key)
)

QUESTION: 12 Topic: KOTLIN only

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:

val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString(
context!!.getString(R.string.pref_sort_key),
context!!.resources.getBoolean(R.bool.pref_default_sort_value)
)
val sortBy = PreferenceManager.getSharedPreferences(context).getString(
context!!.getString(R.string.pref_default_sort_value),
context!!.getString(R.string.pref_sort_key),
)
val sortBy = PreferenceManager.getSharedPreferences(context).getBoolean(
context!!.resources.getBoolean(R.bool.pref_default_sort_value),
context!!.getString(R.string.pref_sort_key)
)
val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString(
context!!.getString(R.string.pref_sort_key),
context!!.getString(R.string.pref_default_sort_value)
)

InputStream for reading it, from out Context context, we can do this:

val input = context!!.openRawResource(R.raw.sample_teas)
val input = context!!.getRawResource(R.raw.sample_teas)
val input = context!!.resources.openRawResource(R.raw.sample_teas)

QUESTION: 14 Topic: KOTLIN only

For example, we have a BufferedReader reader, associated with the json file through
InputStreamReader. To get a file data we can do this:

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()
}
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()
}
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()
}
