Кнопка «Плавающее действие» работает только на Android 5.0 или выше (API 21) ⇐ Android

[Anonymous]

Я создал приложение, которое использует кнопку плавающего действия (FAB). Моя проблема в том, что FAB не работает на API
Это манифест: < /p>














< /code>

Есть два файла Gradle: < /p>
// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

allprojects {
repositories {
jcenter()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}
< /code>
и < /p>
plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
applicationId "eu.mygamesapp.mygames"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

< /code>
Это то, что должен делать Fab: < /p>
private void floatingActionButtonManagement() {
FloatingActionButton fab_addGame = (FloatingActionButton)findViewById(R.id.fab_AddGame);
fab_addGame.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
/*
The currentConsole TextView is used to show at the user which console is selected.
We use it to have a string that contains the selected console.
Call the method that manage the click event of the FloatingActionButton. We pass the console name.
*/
String currentConsoleName = currentConsole.getText().toString();

floatingActionButtonClickEvent(currentConsoleName);
}
});
}

private void floatingActionButtonClickEvent(String currentConsoleName) {
/*
Check if user have added a console. If he did start a menu for adding games, else start an
error message
*/
if (!currentConsoleName.equals(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE)) {
popUpViewAddGameBuild(currentConsoleName);
}
else
mySimpleAlertDialogMethod("Attention!", "Before you enter game, you must enter a console.", true, true);
}

private void popUpViewAddGameBuild(String currentConsoleName) {
/*
Build the view that show the menu for adding games.
*/
LayoutInflater inflater = this.getLayoutInflater();
View popupView = inflater.inflate(R.layout.popupview_addgame, null);
PopupWindow popupWindow = new PopupWindow(
popupView,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT);
popupWindow.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
popupWindow.setFocusable(true);
popupWindow.showAtLocation(popupView, 0, 0, 0);

popUpAddGameSetFullAdapter(popupView, currentConsoleName);
popUpAddGameClickEventManagment(popupView, popupWindow, currentConsoleName);
}

private void popUpAddGameSetFullAdapter(View popupView, String currentConsoleName) {
/*
Fill the listView with all the games of the current console
*/
ListView lstvw_addVideoGamePopUp_listOfAllGames = (ListView) popupView.findViewById(R.id.listView_all_games);

Cursor cursor = appDataBase.getAllCurrentConsoleGames(currentConsoleName);
String[] fromFieldNames = new String[]{AppDataBase.COL_VIDEOGAME_NAME};

int[] toViewsIDs = new int[]{R.id.txt_popUpViewAddGame_lstvw_name};
SimpleCursorAdapter myCursorAdapter = new SimpleCursorAdapter(popupView.getContext(), R.layout.listview_allcurrentconsolegames, cursor, fromFieldNames, toViewsIDs, 0);
lstvw_addVideoGamePopUp_listOfAllGames.setAdapter(myCursorAdapter);
}
< /code>
Я не имею представления, в чем может быть проблема. Что мне делать?
