How to position ViewPager above RecyclerView?

This xml layout has been populated by ViewPager and RecyclerView via an activity class, I want to position ViewPager on top and RecyclerView at the bottom, I tired to use android:layout_below="#+id/awesomepager" in the LinearLayout of RecyclerView but it doesn't work (it stays on top behind the toolbar[Deep blue color in the picture]), I also used android:layout_alignBottom="#+id/awesomepager" but that puts it inside the ViewPager at the bottom.
I basically want ViewPager and RecyclerView to be siblings , like this picture , black area to be ViewPager at the top and the green area to be RecyclerView at the bottom.
what is correct way to do this?
viewpager_with_toolbar_overlay.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ProgressBar
android:id="#+id/progressbar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v4.view.ViewPager
android:id="#+id/awesomepager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="70dp"
android:background="#068006"
android:layout_below="#+id/awesomepager"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/episodesLIST"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:scrollbars="horizontal" />
</LinearLayout>
</RelativeLayout>
<include layout="#layout/toolbar_layout" />
</FrameLayout>
Update:
If I define the hight of ViewPager the problem will be resolved , but when screen size changes lower part of the screen will be blank
I searched a lot and finally came up with a solution, first I changed RelativeLayout to LinearLayout and added android:orientation="vertical" to it, then added android:layout_weight="1" to ViewPager.
Final version
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ProgressBar
android:id="#+id/progressbar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"

<android.support.v4.view.ViewPager
android:id="#+id/awesomepager"
android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="70dp"

BottomSheet move to top of screen when changing visibility of its component

I have a bottom sheet with a NestedScrollView inside (see below). When I press on a FAB button, I want to make some parts in this NestedScrollView invisible. But when I change some linearlayouts visibilities to GONE, bottomsheet fly aways from the top.
My XML 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"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/messageOptionBottomSheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/back_miscellaneous"
android:gravity="center"
android:orientation="vertical"
app:behavior_peekHeight="0dp"
app:layout_behavior="#string/bottom_sheet_behavior">
<View
android:id="#+id/divider2"
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/textSecondary" />
<LinearLayout
android:id="#+id/layoutDeleteMessage"
android:layout_width="match_parent"
android:layout_height="#dimen/_35sdp"
android:layout_margin="#dimen/_10sdp"
android:gravity="center_vertical"
android:orientation="horizontal"
android:animateLayoutChanges="true"
tools:ignore="UseCompoundDrawables">
<ImageView
android:layout_width="#dimen/_22sdp"
android:layout_height="#dimen/_22sdp"
android:contentDescription="#string/app_name"
android:src="#drawable/ic_remove" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="#dimen/_10sdp"
android:fontFamily="#font/ubuntu_medium"
android:includeFontPadding="false"
android:text="#string/delete_message"
android:textColor="#color/textSecondary"
android:textSize="#dimen/_12ssp" />
<TextView
android:id="#+id/textConfirmDelete"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="#dimen/_10sdp"
android:fontFamily="#font/ubuntu_medium"
android:gravity="end"
android:includeFontPadding="false"
android:text="#string/confirm"
android:textColor="#color/red"
android:textSize="#dimen/_12ssp"
android:visibility="gone" />
</LinearLayout>
</LinearLayout>
Your bottom sheet is moving top because you are using
android:animateLayoutChanges="true"
remove this line from your layoutDeleteMessage (Linear layout)
Hope this solve your problem

Checkbox text is not vertically aligned to the centre of the checkbox

I have 5 checkboxes and each checkbox's' text is misaligned vertically from the center of the checkbox. I have tried adding a padding or a marging to the chckbox which has not helped, cause to my knowledge you can't add a padding specifically to the text. Heres an image that might explain my problem a little better!
Checkbox text is misaligned on the first checkbox. The result I want is the 4th checkbox.
EDIT
I create the checkboxes programmatically from an array:
LinearLayout typeLinLayout = (LinearLayout)findViewById(R.id.typeLinLay);
TableRow.LayoutParams checkParams = new TableRow.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
checkParams.setMargins(0, 15, 0, 0);
for (int k = 0; k < config.checkBoxTypeFindViewById.length; k++)
{
CheckBox checkBox = new CheckBox(this);
checkBox.setLayoutParams(checkParams);
typeLinLayout.addView(checkBox, checkParams);
checkBox.setId(config.checkBoxTypeFindViewById[k]);
checkBox.setText(config.checkBoxTextType[k]);
checkBox.setOnClickListener(onCheckboxClickedType);
checkBox.setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
checkBox.setGravity(Gravity.LEFT);
checkBox.setTextDirection(View.TEXT_DIRECTION_ANY_RTL);
checkBox.setTextSize(16);
checkBox.setAllCaps(true);
}
Heres the xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView

android:background="#color/mainTextBGColor">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginStart="15dp"
android:layout_marginEnd="15dp">
<TextView
android:id="#+id/typesText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="30dp"
android:layout_marginBottom="10dp"
android:textSize="#dimen/optionsHeaders"
android:fontFamily="#font/lato"
android:textColor="#color/mainBGColor"
android:text="#string/optionsType"/>
<LinearLayout
android:id="#+id/typeLinLay"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:backgroundTint="#color/mainBGColor">
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>
Any help is much appreciated!

</ScrollView>
A couple of items:
1) You have a dangling '>' near the end of your code.
2) If you want to just scroll the TextView, then only wrap the textview in the scrollview, see Scroll view for textview in android for an example.
