Replace fragment inside fragment :Exception No view found for id 0x

I have one fragment and I try to replace some another fragment in my layout.Here is a fragment replace code
public static void replace(FragmentManager fm, Fragment fragment, int container, String tag) {
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(container, fragment, tag);
fragmentTransaction.commit();
}
Here is a main code
if (cardList != null && cardList.isEmpty()) {
hideDialog(pDialog);
drawavleView.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
norecordfragment = new NoRecordFragment();
norecordfragment.setAvatar(R.drawable.ic_card_nocard);
norecordfragment.setText(getActivity().getString(R.string.u_cards_no_data_text));
norecordfragment.setButtontext(getActivity().getString(R.string.u_cards_no_data_action));
norecordfragment.setAllowToShowAddAction(false);
floatingActionButton.setVisibility(View.VISIBLE);
FragmentUtils.replace(getActivity().getSupportFragmentManager(), norecordfragment,
R.id.upload_main_layout_upload,"norecordfragment");
}
Here is my xml code

I don't know why in some devices I have this exception.
Exception java.lang.IllegalArgumentException: No view found for id 0x7f09052f (com.me.myapp:id/upload_main_layout_upload) for fragment NoRecordFragment{5309279 #4 id=0x7f09052f norecordfragment}
As you can see, I tried to replace my custom fragment inside upload_main_layout_upload layout, but I have this exception. What am I doing wrong? Thanks.

To implement a Fragment inside another layout, you need to have the layout that you are showing inside the Fragment in another fragment_layout.xml file. So you need to modify your current layout as follows.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:fitsSystemWindows="false">
<ScrollView 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="match_parent"
android:fillViewport="true"
android:minHeight="#dimen/u_base_min_height">
<RelativeLayout
android:id="#+id/upload_main_layout_upload"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"/>
</ScrollView>
<LinearLayout
android:id="#+id/floating_action_bar_transparent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#4D000000"
android:clickable="true"
android:orientation="vertical"
android:visibility="gone" />
<android.support.design.widget.FloatingActionButton xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/floating_action_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_add_white"
app:backgroundTint="#48c9ff" />
</android.support.design.widget.CoordinatorLayout>
And take the content inside the RelativeLayout outside of this layout and create another layout which will be used in your Fragment to get views from there.
Here's a sample fragment_layout.xml.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/lay_v3"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:orientation="vertical">

android:layout_width="match_parent"
android:layout_height="#dimen/transfer_headerView_height"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#f2f2f2" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/u_common_margin_left"
android:layout_marginRight="#dimen/u_common_margin_left"
android:layout_marginTop="#dimen/withdrow_change_card_height"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="#dimen/u_widget_height"
android:background="#drawable/edittext_input_background_not_focus"
android:orientation="horizontal">
<EditText
android:id="#+id/u_major_text"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_marginBottom="7dp"
android:layout_marginLeft="5dp"
android:layout_weight="0.65"
android:background="#null"
android:gravity="left"
android:hint="0.00"
android:imeOptions="actionDone"
android:inputType="numberDecimal"
android:maxLines="1"
android:singleLine="true"
android:textColor="#4d4d4d"

android:textSize="35dp" />
<Spinner
android:id="#+id/upload_spinner"
style="#style/Widget.MyApp.HeaderBar.Spinner"
android:layout_width="80dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:background="#drawable/edittext_input_background_not_focus" />
<ImageView
android:id="#+id/u_open_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/transfer_user_description"

You have too many nested layouts inside one as far as I can see. You need to rearrange your layouts as per your requirement and transaction flows between Activity and Fragments.

Issue with listview scrollable

i don't know why my list view doesn't scroll completely.
I show you also single list view item.XML about adapter's xml where i put the item for every rows of my listview, so i hope that you can help me!

In your adapter's xml , RelativeLayout tag ,write wrap_content replace of match_parent like below;
android:layout_height="wrap_content"

Change your single_listview_item.XML's RelativeLayout from android:layout_height="match_parent" to android:layout_height="wrap_content"
Change your ListView's height to wrap_content too

XML layout 2 views in centre, one at top

I created linearlayout with two buttons in center (buttons 1 and 2), but I can't manage it to create the view 3 on top, which I need to make it fill whole width and adjust it's height by it (keep proportions). How do I create third view?
Image:
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg"
android:layout_gravity="center_horizontal"
android:orientation="horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent" android:layout_height="wrap_content" >
<ImageButton
android:background="#drawable/btn_one"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1.0" />
<ImageButton
android:background="#drawable/btn_second"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1.0" />
</LinearLayout>

I would recommend you use relative layouts, they are the closest thing in android to an "absolute layout" replace the button tags with Image button tags
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true">
</RelativeLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button2"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="215dp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button3"
android:layout_below="#+id/button2"
android:layout_alignStart="#+id/button2" />
</RelativeLayout>

try this code set height and width what size of image button you need and simple look what you need.
<?xml version="1.0" encoding="utf-8"?>

Floating Action Button between two tabs

I have a fab and would like to have it during the passage between two tabs, tried to put the transparent background in fragment_main.xml but without success.

Eihschnaehkeee is right -- you just need a layout that allows overlapping. Here is XML to try (also adding right margin for your button):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:fab="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#0000">
<br.com.test.common.view.SlidingTabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/sliding_tabs"
android:layout_alignParentBottom="true"
android:background="#0000"/>
<com.getbase.floatingactionbutton.FloatingActionButton
android:id="#+id/pink_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
fab:fab_icon="#drawable/ic_add"
fab:fab_colorNormal="#color/material_orange_500"
fab:fab_colorPressed="#color/material_orange_a200"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp"/>
</RelativeLayout >

Eihschnaehkeee and Bruce.
I tried to put as relative layout and swipe funcinou not more, I tried using SlidingTabLayout the android code https://github.com/googlesamples/android-SlidingTabsBasic/

Center vertically listview

I have a listview and a layout that is displayed in this way:
I wish that the items were also centered vertically. How can I do? this is the code
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+ListView/id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="24dp"
android:text="invisibile"
android:visibility="gone" />
<TextView
android:id="#+ListView2/x"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_marginTop="22dp"
android:text="TextView"
android:textSize="24dp" />
</RelativeLayout>

You have to create your own layout for your listview item. Soemthing
like this
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center" >
<TextView
android:id="#id/textItem"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Then, in your code, your going to have to do this
new ArrayAdapter(this, R.layout.yourRowItemLayoutHere,
