Can We get scrollable view for particular child layout in android - android

Iam developing an android application where i need scrollable view for particular child layout which is scrollable if it possible please suggest below are pictorial explanation.
below are code for explanation.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context="android.xyz.com.xyz.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="3dp"
android:orientation="vertical">
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:orientation="vertical"
android:scrollbars="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/ntitled" />
</LinearLayout>
</ScrollView>
<LinearLayout

android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/ic_tp"
/>
</LinearLayout>
</LinearLayout>

Edit1: For the clarification.
You can do that adding code like this in your .xml layout:
<?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/LinearLayout1"
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">
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/nreg" />
<EditText
android:id="#+id/txtReg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="5"
android:ems="10"
android:inputType="number">
<requestFocus />
</EditText>
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/val" />
<EditText
android:id="#+id/txtVal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:inputType="text"/>
</LinearLayout>
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<Button
android:id="#+id/btnInsertar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/ins" />
<Button
android:id="#+id/btnActualizar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/act" />
<Button
android:id="#+id/btnEliminar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/elim" />
<Button
android:id="#+id/btnConsultar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/cons" />
<Button
android:id="#+id/gaf"
android:layout_width="wrap_content"

Making a RelativeLayout scrollable

I want my RelativeLayout to be scrollable in Landscape.
I tried doing this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".RelativeActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/headline_icon" />
<TextView
android:id="#+id/relative_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/layout_uebersicht" />
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/relative_textview"
android:layout_centerHorizontal="true"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/relativebutton_linearlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonLinearLayoutClick"
android:text="#string/linear_layout" />
<Button
android:id="#+id/relativebutton_tablelayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonTableLayoutClick"
android:text="#string/table_layout" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/relativebutton_framelayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonFrameLayoutClick"
android:text="#string/frame_layout" />
<Button
android:id="#+id/relativebutton_gridlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonGridLayoutClick"
android:text="#string/grid_layout" />
</LinearLayout>
</LinearLayout>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:src="#drawable/baseline_icon" />
</RelativeLayout>
</ScrollView>
But it messes everything up like this
I have also tried putting a simple LinearLayout between the ScrollView and the RelativeLayout and switching all the layout_height and width values around. None of this will work.
The android:fillViewport="true" does not work either.
My code looks like this without the ScrollView:
<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"
android:padding="16dp"
tools:context=".RelativeActivity">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/headline_icon" />
<TextView
android:id="#+id/relative_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/layout_uebersicht" />
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/relative_textview"
android:layout_centerHorizontal="true"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/relativebutton_linearlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonLinearLayoutClick"
android:text="#string/linear_layout" />
<Button
android:id="#+id/relativebutton_tablelayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonTableLayoutClick"
android:text="#string/table_layout" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/relativebutton_framelayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonFrameLayoutClick"
android:text="#string/frame_layout" />
<Button
android:id="#+id/relativebutton_gridlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonGridLayoutClick"
android:text="#string/grid_layout" />
</LinearLayout>
</LinearLayout>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:src="#drawable/baseline_icon" />
</RelativeLayout>

Create a HorizontalScrollView and inside it , design your RelativeLayout like this :
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="16dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/headline_icon" />
<TextView
android:id="#+id/relative_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/layout_uebersicht" />
<LinearLayout
android:id="#+id/ll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/relative_textview"
android:layout_centerHorizontal="true"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/relativebutton_linearlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonLinearLayoutClick"
android:text="#string/linear_layout" />
<Button
android:id="#+id/relativebutton_tablelayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonTableLayoutClick"
android:text="#string/table_layout" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/relativebutton_framelayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonFrameLayoutClick"
android:text="#string/frame_layout" />
<Button
android:id="#+id/relativebutton_gridlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onButtonGridLayoutClick"
android:text="#string/grid_layout" />
</LinearLayout>
</LinearLayout>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:src="#drawable/baseline_icon" />
</RelativeLayout>
</HorizontalScrollView>
Consider that your RelativeLayout width should be wrap_content

android:layout_height="wrap_content"
android:text="#string/total"
android:textStyle="bold" />
<TextView
android:id="#+id/textViewTotalPrice"
android:layout_width="match_parent"

android:drawableEnd="#drawable/ic_arrow_forward"
android:paddingEnd="15dp"

android:textColor="#color/white" />
</LinearLayout>
This is the way i want.

Try this
<?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">
<include layout="#layout/toolbar_layout" />
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerViewCart"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="total"
android:textStyle="bold" />
<TextView
android:id="#+id/textViewTotalPrice"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="$23.00" />
</LinearLayout>
<Button
android:id="#+id/buttonCheckout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginRight="20dp"
android:background="#color/colorPrimary"
android:drawableEnd="#drawable/ic_arrow_forward"
android:paddingEnd="15dp"
android:text="#string/checkout"
android:textColor="#color/white" />
</LinearLayout>
</LinearLayout>

Put Space layout between RecyclerView and LinearLayout
<Space
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
or use RelativeLayout instead of your main LinearLayout

Try this code.. and change this
<?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">
<include layout="#layout/toolbar_layout" />
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerViewCart"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="tees"
android:textStyle="bold" />
<TextView
android:id="#+id/textViewTotalPrice"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="$23.00" />
</LinearLayout>
<Button
android:id="#+id/buttonCheckout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginEnd="20dp"
android:layout_weight="1"
android:background="#color/colorPrimary"
android:paddingEnd="15dp"
android:text="Hello" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>

Add Textview On Viewflipper

i want show description of images in Viewflipper slidshow.I need to add textview or button on a viewflipper slideshow.So that only i can display image description based on textview or button click on viewflipper this is my xml
<?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"
android:scaleType="fitXY" >
<ViewFlipper
android:id="#+id/myflipper"
android:layout_width="match_parent"
android:layout_height="300dp"
android:gravity="center"
android:scaleType="fitXY" >
</ViewFlipper>
</LinearLayout>

You can use a FrameLayout for placing TextView over ViewFlipper like shown here:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/tools"
android:id="#+id/framelayout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ViewFlipper
android:id="#+id/myflipper"
android:layout_width="match_parent"
android:layout_height="300dp"
android:gravity="center"
android:scaleType="fitXY" >
</ViewFlipper>
<TextView
android:id="#+id/mytext"
android:layout_width="match_parent"
android:layout_height="30dp"/>
</FrameLayout>
Check out this sample program blog for more examples of how to use FrameLayout.
Happy coding :)

You can use from this way in your Layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/KeepToolbar"

Android map with custom layout

I' am trying to achieve sth like this:
But the ListView is overlaps my bottom bar. What is the best way to prevent such a behaviour? As you can see in the picture there is a map under bottom bar. This bottom bar is like target/destination window in Google Maps app.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="#+id/map"
tools:layout="#layout/fragmentMap"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:layout_marginTop="2dp"
android:orientation="vertical">
<EditText
android:id="#+id/mapEditT"
android:layout_width="fill_parent"
android:layout_height="53dp"
android:layout_alignParentTop="true"
android:gravity="center|left"
android:paddingLeft="2dp"
android:paddingRight="0dp"/>

<TextView

</FrameLayout>

Use LinearLayout or RelativeLayout as top most parent instead of FrameLayout.
Here is the code snippet using LinearLayout.
<?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" >
<EditText
android:id="#+id/textView1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_vertical" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
</ListView>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageButton
android:id="#+id/draweR"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="left|center_vertical"
android:src="#drawable/draweR"/>
<com.google.android.gms.maps.MapView
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="#layout/fragmentMap" />
</FrameLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="100" >
<TextView
android:id="#+id/textView2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="TextView"
android:layout_weight="75" />
<TextView
android:id="#+id/textView3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="TextView"
android:layout_weight="25" />
</LinearLayout>
</LinearLayout>

You can mess around with the margins. I got it to look like the image you wanted.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.google.android.gms.maps.MapView
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout="#layout/fragmentMap" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:layout_marginTop="2dp"
android:orientation="vertical"
android:paddingBottom="160dp" >

Android ViewPager with android:layout_weight="1" is not shown

I want to display a scroll view within ViewPager and action buttons below the ViewPager. So I set android:layout_weight="1" to ViewPager, but it was not displayed, and only action buttons was displayed.
The layout of ViewPager is following.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_weight="1" />
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:paddingBottom="10dp"
android:text="この記事の投稿者に" />
<LinearLayout
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:gravity="center">
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="メールで問い合わせ" />
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="電話で問い合わせ" />
</LinearLayout>
</LinearLayout>
The layout within ViewPager is following.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_width="match_parent">
<ScrollView
android:layout_height="match_parent"
android:layout_width="match_parent"
android:fillViewport="true">
<LinearLayout
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_width="match_parent">
<TextView
android:id="#+id/title"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:textSize="21sp" />
<ImageView
android:id="#+id/image"
android:layout_height="200dp"
android:layout_width="200dp"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:layout_gravity="center" />
<TextView

android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:textSize="34sp"
android:textColor="#FF0000" />
<TextView
android:id="#+id/text"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:textSize="21sp" />
</LinearLayout>
</ScrollView>
</LinearLayout>

When you are using weights with Layouts you need to use a height or width, depending on the orientation, of "0dp"
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_height="0dp"
android:layout_width="match_parent"
android:layout_weight="0.8" />
<LinearLayout
android:orientation="vertical"
android:layout_height="0dp"
android:layout_width="match_parent"
android:weight="0.2">
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:paddingBottom="10dp"
android:text="この記事の投稿者に" />
<LinearLayout
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:gravity="center">
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="メールで問い合わせ" />
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="電話で問い合わせ" />
</LinearLayout>

This should do the trick:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_width="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_weight="0" />
<LinearLayout
android:orientation="vertical"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_weight="1">
</LinearLayout>
</LinearLayout>
