The issue is in your list_item_layout file. There is an issue with match_parent in your layout try using below code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:orientation="horizontal">
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:height="70dp"
android:gravity="center"
android:text="TextView"
android:textSize="18sp" />
<ImageView
android:id="#+id/imageView"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_weight="2"
app:srcCompat="#mipmap/ic_launcher" />

The problem was caused by the text colour , changing the colour of textview text in list_item_layout resolved the issue.

Sliding Menu Like Facebook in Material Design theme in Android

I have made a sliding menu like that of facebook by following the tutorial which is available in the following site:
http://www.devexchanges.info/2016/05/creating-your-own-sliding-menu-like.html?m=1
Now in the main layout I have added a long paragraph of text so in order to view everything I used ScrollView. But when I use ScrollView I cannot pull the menu out, I can only open the drawer by clicking on the button. Please help me on how to scroll through the para and also be able to pull the menu drawer.

try this instead of Fragments container. add this code below

From what i understand of your succinct problem, just cut/paste the following:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/welcome"
android:textSize="20dp" />
<Button
android:id="#+id/btnLogout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="40dip"
android:background="#color/btn_logut_bg"
android:text="#string/btn_logout"
android:textAllCaps="false"
android:textColor="#color/white"
android:textSize="15dp" />
In the tab_profile.xml, and you will be good! That's the file you have to work on to personalize your fragment.

Activity is hidden by fragment, it is not useable

i have builded an app that works perfectly on android with api higer than 21. The problem is that this instruction of my code:
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
Works in different way on API less then 21.
On Api less then 21 the new fragment hide the previus activity, so that i can't click on my Floating Action Button.
Here are two images that explain in abetter way my problem.
API HIGER THAN 21
API LESS THAN 21
So my question is: How can i have the same result in API less then 21 that i have on API Higer then 21?
Here is the affected part of the Main Activity Code:
public class MainActivity extends AppCompatActivity {
public static AppDataBase appDataBase;
public static UserDataBase userDataBase;
static FragmentManager mFragmentManager;
static FragmentTransaction mFragmentTransaction;
private DrawerLayout myDrawerLayout;
final String TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE = "Add a console!";
TextView currentConsole;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
appDataBase = new AppDataBase(this);
userDataBase = new UserDataBase(this);
myDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
currentConsole = (TextView) findViewById(R.id.txt_Mainactvt_currentConsole);
currentConsole.setText(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE);
tabLayoutManagement();
floatingActionButtonManagement();
leftDrawerMenuManagement();
rigthDrawerMenuManagement();
populateMyConsole();
}
void tabLayoutManagement() {
mFragmentManager = getSupportFragmentManager();
mFragmentTransaction = mFragmentManager.beginTransaction();
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
}
// Floating Action Button
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 wich console is selected.
We use it to have a strng that conteins 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);
}
Here is the TabLayout Class:
public class TabFragment extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View x = inflater.inflate(R.layout.tab_layout, null);
tabLayout = (TabLayout) x.findViewById(R.id.tabs);
viewPager = (ViewPager) x.findViewById(R.id.viewpager);
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.post(new Runnable() {
#Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return x;
}
public class MyAdapter extends FragmentPagerAdapter {
public int position;
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0 :
return new DesireFragment();
case 1 :
return new BuyedFragment();
case 2 :
return new StartedFragment();
case 3 :
return new FinishedFragment();
case 4 :
return new AllTrophiesFragment();
}
return null;
}
#Override
public int getCount() {
return 5;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0 :
return "Desire";
case 1 :
return "Buyed";
case 2 :
return "Started";
case 3 :
return "Finished";
case 4 :
return "AllTrophies";
}
return null;
}
}
}
There is the layout of the MainActivity:
<LinearLayout

xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

android:scrollbars="vertical"

</android.support.v4.widget.DrawerLayout>
And here is the layout code of the TabLayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="wrap_content">

app:tabMode="scrollable"
android:background="#color/colorPrimary"
app:tabIndicatorColor="#android:color/holo_orange_dark"
app:tabSelectedTextColor="#android:color/holo_orange_dark"
app:tabTextColor="#android:color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

You replace the content of your FrameLayout with an Fragment. this leads to your strange result.
Add a Layout to your Framelayout instead and use it as your FragmentContainer:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:backgroundTint="#color/colorPrimary"
app:borderWidth="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="30dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="#+id/txt_Mainactvt_currentConsole"
android:layout_gravity="center_horizontal|top"
android:layout_marginTop="50dp"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab_AddGame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="17dp"
android:layout_marginRight="17dp"
android:src="#drawable/ic_mode_edit_white_24dp"
android:layout_gravity="bottom|right"
android:background="#color/colorPrimary" />
</FrameLayout>

Try to place your FrameLayout with this button to the end of layout
