layout_weight is not working inside ScrollView

I can't figure out , why layout_weight is not working inside the ScrollView , when i am running this xml , i am getting imageview capturing the whole screen and below that i can see my tabs and the viewpager got hidden .
When i am giving the height in dp to all the linear layout below the ScrollView , i am getting my view perfectly ,why it's happening . i want my imageview to take 30% screen and tab/viewpager to take 70% of screen.

None of the above solution worked for me , i found the solution myself like this : hope it will help someone : No changes in the tab code . In the main xml , i have done like this :

Here comes the important part : Pragmatically set the height of the child layout :D
private void setViewPagerandImageViewHeight(){
DisplayMetrics displayMetrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int heightOfScreen = displayMetrics.heightPixels;
child_img_ll.getLayoutParams().height= (int) (heightOfScreen*.30);// set imageview linearlayout to capture 30% of screen
viewpager_ll.getLayoutParams().height=heightOfScreen;//while scrolling set the viewpager height to maximum ,intially it capture 70% of screen
}

Edittext and a button followed by recycler view

I have an empty Activity with RelativeLayout and RecyclerView
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:="match_parent"
android:layout_height="match_parent"
app:layout_behavilayout_widthor="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/activity_main"
tools:context=".MainActivity">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
I need an EditText and a button to be added before RecyclerView.
I guess RecyclerView's padding height should be changed but not sure! Please help me

Try this out. Make your parent layout as Linear layout, your views will get stacked.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="textPersonName"
android:text="Name"
android:layout_toStartOf="#+id/button" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_alignParentEnd="true"/>
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>

Change the LinearLayout to "Vertical" orientation
Use android:layout_weight Property.
Indicates how much of the extra space in the LinearLayout is allocated
to the view associated with these LayoutParams.
Example
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/et_ONE"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:id="#+id/button_ONE"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:text="Button"
android:layout_weight="1"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="3"/>
</LinearLayout>
You can try with
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavilayout_widthor="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/activity_main"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/et_ONE"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1" />
<Button
android:id="#+id/button_ONE"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:text="Button"
android:layout_weight="1"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="3"/>
</LinearLayout>
</RelativeLayout>

is this you want?
<?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:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent" />

Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="EditText"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>

Use a LinearLayout before RecyclerView and and provide them an ID(e.g. temp) and use RelativeLayout property layout_below with the RecyclerView, like this android:layout_below="#id/temp"(it will make sure that your RecyclerView will always below then LinearLayout), Now Add your Button and EditText into that LinearLayout (Make sure that LinearLayout should be wrap_content into height)
Use this code, Edit according to your requirement
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:="match_parent"
app:layout_behavilayout_widthor="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/activity_main"
tools:context=".MainActivity">
<LinearLayout
android:id="#+id/temp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<EditText
android:id="#+id/editText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:inputType="textPersonName"
android:text="Name" />
<Button

</LinearLayout>

Create a bottom 3 section pane on android

How can I create the below layout in Android? I want the bottom bar to have a fixed size and the above-panel to grow based on the device size. Is there a library that's available to have the below effect?
Right now I used a relative layout but the height of the top panel doesn't grow.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="400dp">
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_weight="0.71"
android:layout_below="#+id/linearLayout"
android:layout_height="150dp"></LinearLayout>
</RelativeLayout>

Try like this
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_above="#+id/tab_bar"
android:layout_height="match_parent">
</LinearLayout>
<LinearLayout
android:id="#+id/tab_bar"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_height="150dp"></LinearLayout>
</RelativeLayout>

You need to set android:layout_height="0dp" and android:layout_weight="1".
Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_second"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.amrizal.example.firebasetester.SecondActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#android:color/darker_gray">
<TextView
android:text="Section 1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="30dp"
android:background="#android:color/holo_blue_bright">
<TextView
android:text="Section 2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"/>
</RelativeLayout>
</LinearLayout>

How do I get an imageView and textview to both fill the layout when setting bitmap programmatically?

What I want is for qrcodetext to fit and display all the text in qrcode_layout and have qrimageView to fill the rest of qrcode_layout? But my layout below has the entire qrimageView cover qrcode_layout. I tried a bunch of other variations but without success.
Here is what it looks like.

android:layout_width="match_parent"
android:layout_height="match_parent">

Use following code. Align your textview to bottom and then align your Qrcode Image above text:
<?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">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/qrcodetext"
android:gravity="center"
android:layout_alignParentBottom="true"
android:layout_marginTop="4dp" />
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/qrimageView"
android:layout_gravity="center_horizontal"
android:layout_above="#id/qrcodetext"
android:layout_alignParentTop="true"
android:layout_marginTop="8dp" />
</RelativeLayout>

I think what i have understand you want is below: Plz check and tell me:
