PreferenceFragment inflated onto CardView - android

I'm having difficulty getting the layout_height right inflating a PreferenceFragment onto a CardView.
Everything works well, including the NestedScrollView to collapse my Toolbar, but for some reason my Preferences are only filling the first position of the list. It's scrollable, but it needs to fill the entire Card.
Any ideas on what might be going on here?
Edit: It's definitely the NestedScrollView causing the problem. Now if only I can find a workaround..
I might also not fully understand Cards, since other Layouts, I can't seem to get them to entirely fill the View, minus that little bit of margin.
Here's my PreferenceFragment XML
<android.support.v7.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/tools"
android:id="#+id/cardview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:elevation="100dp"
android:layout_gravity="center"
android:layout_margin="10dp"
card_view:cardBackgroundColor="#color/cardview_initial_background"
card_view:cardCornerRadius="10dp"

<android.support.v4.widget.NestedScrollView
android:id="#+id/nestedScrollView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="#dimen/scrollview_padding_default" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:background="#android:color/transparent">
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1"
android:paddingTop="0dip"

<TextView

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="#dimen/preference_fragment_padding_side"
android:gravity="center"
android:visibility="gone" />
<RelativeLayout
android:id="#+id/button_bar"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="0"
android:visibility="gone">
<Button
android:id="#+id/back_button"
android:layout_width="150dip"
android:layout_height="wrap_content"
android:layout_margin="5dip"
android:layout_alignParentLeft="true"
android:text="#string/back_button_label"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true">
<Button
android:id="#+id/skip_button"
android:layout_width="150dip"
android:layout_height="wrap_content"
android:layout_margin="5dip"
android:text="#string/skip_button_label"
android:visibility="gone"/>
<Button
android:id="#+id/next_button"
android:layout_width="150dip"
android:layout_height="wrap_content"
android:layout_margin="5dip"
android:text="#string/next_button_label"/>
</LinearLayout>
</RelativeLayout>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.v7.widget.CardView>
And my PreferenceFragment Java, where the inflation happens:
package app.my.sample;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import app.my.sample.R;
public class SettingsPreferenceFragment extends PreferenceFragment {
public static final String ARG_PAGE = "ARG_PAGE";
private int mPage;
public static SettingsPreferenceFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
SettingsPreferenceFragment fragment = new SettingsPreferenceFragment();
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mPage = getArguments().getInt(ARG_PAGE);
addPreferencesFromResource(R.xml.preferences);
}
#Override
public View onCreateView(LayoutInflater paramLayoutInflater, ViewGroup paramViewGroup, Bundle paramBundle) {
return paramLayoutInflater.inflate(R.layout.fragment_preference_list, paramViewGroup , false);
//return super.onCreateView(paramLayoutInflater, paramViewGroup, paramBundle);
}
}


It's an old question but maybe someone will find this answer useful.
Try Adding attribute android:fillViewport="true" to NestedScrollView.

Expected Result ( Working correctly on Tablet with Android 4.4.2 with below code)
Actual Results ( Tested on multiple phones with OS >= 8.1.0)

I Have tried your code but unable to reproduce this output
For me your code is working fine check the output
Result in Oreo
Result in android pie
Result in android Q
as per my opinion you should use
You should use RecyclerView with GridLayoutManager
Follow this sample code
Add one recyclerview in your activity layout xml file
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="0dp"
android:gravity="center">
<androidx.recyclerview.widget.RecyclerView
android:layout_width="wrap_content"
android:id="#+id/gridRecyclerView"
android:layout_centerInParent="true"
android:layout_height="wrap_content"/>
</RelativeLayout>
Now inside your activity set GridLayoutManager to your RecyclerView
GridLayoutManager (Context context,
int spanCount)
Creates a vertical GridLayoutManager
Parameters
context Context: Current context, will be used to access resources.
spanCount int: The number of columns in the grid
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.GridLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
public class JavaActivity extends AppCompatActivity {
RecyclerView myRecyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_java);
myRecyclerView = findViewById(R.id.gridRecyclerView);
GridLayoutManager gridLayoutManager = new GridLayoutManager(JavaActivity.this, 6);
myRecyclerView.setLayoutManager(gridLayoutManager);
myRecyclerView.setAdapter(new MyAdapter(this));
}
}
Create one adapter class RecyclerView like this
import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
private Context context;
public MyAdapter(Context context) {
this.context = context;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.row_list_item, parent, false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int position) {
if (position%2==0){
holder.imgBanner.setBackgroundColor(Color.BLUE);
}else {
holder.imgBanner.setBackgroundColor(Color.GREEN);
holder.imgBanner.setImageResource(R.drawable.red_heart);
}
}
#Override
public int getItemCount() {
return 36;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
ImageView imgBanner;
public MyViewHolder(#NonNull View itemView) {
super(itemView);
imgBanner = itemView.findViewById(R.id.imgBanner);
}
}
}
Create one layout file for RecyclerView item
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_margin="2dp"
android:orientation="vertical">
<ImageView
android:id="#+id/imgBanner"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
/>
</RelativeLayout>

Try with a padding like this:
<RelativeLayout
android:id="#+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="someDp" ->>>> Padding
android:paddingRight="someDp" ->>>> Padding
android:layout_above="#+id/horizontal_divider"
android:layout_below="#id/toolbar"
android:gravity="center">
<TableLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tblLayout"
android:gravity="center"
android:shrinkColumns="*"
android:padding="0dip"
android:layout_margin="0dip"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"></TableLayout>
</RelativeLayout >

ScrollView not working with GridLayout in android studio

Hi I want to create a responsive scrollable grids. As I search, I came across some codes. I tweaked this code to allow scrolling of the grids. The code creates a 2 column grids and 4 rows with cardViews. The cardViews shrinks to allow more cards into the viewport rather than scrolling. Am open to any ideas and alternative methods to make this work.Thanks in advance.

I have a pattern like that in one of my apps. Tickets get added to the 3-wide grid and you can scroll the grid. Here is the code I use.

}
#Override
public long getItemId(int i) {
return 0;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
View view1 = getLayoutInflater().inflate(R.layout.row_data,null);
//getting view in row_data
TextView name = view1.findViewById(R.id.fruits);
ImageView image = view1.findViewById(R.id.images);
name.setText(fruitNames[i]);
image.setImageResource(fruitImages[i]);
return view1;
}
}
}
I watched diff tuts to come up with this. Am now doubting whether it comforms to best practices. Thanks to you all for your suggestions.

Layout of fragment disintegrates when it dynamically replaces framelayout

I have an app with MainActivity that contains a FrameLayout which would be replaced by a fragment based on which item is clicked in the bottom layout. I have a fragment named "bookings" that must appear in the body area when "Bookings" option is clicked. The "bookings" fragment contains a spinner and a button that are placed at the center of screen inside of RelativeLayout. When the fragment's layout is placed directly inside of body of MainActivity, the spinner and button is centered, just the way I want it to be.

Change height of FrameLayout to match_parent from wrap_content
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottompanel"
android:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_frame"/>
</LinearLayout>

You have match_parent in the height for fragment layout. Try changing it to wrap_content and see if it works

android <merge /> can be used only with a valid viewgroup root and attachtoroot=true

I am trying to inflate a fragment xml that does not have merge anywhere in it. Yet I am being given the error stated in the question.
My fragment class :
package com.xxxxx.www.xxxxxx;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class ExcercisePlanFragment extends Fragment
{
public static ExcercisePlanFragment newInstance()
{
ExcercisePlanFragment fragment = new ExcercisePlanFragment();
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.fragment_excercise_plan, container, false);
}
}
Here is fragment_excercise_plan.xml :
<?xml version="1.0" encoding="utf-8"?>

I have no idea where build.gradle is picking up merge. I have another fragment activity which is working perfectly.

How can I display the layout containing the buttons down on the screen

With the layout below the buttons are being shown on top of the page. How can I make them appear below, after the container, down on the page?
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/container"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_gravity="center_vertical|center_horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/Main"
android:onClick="ClickHomePage"
android:text= "#string/Home"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/map"
android:onClick="ClickClients"
android:text= "#string/Clients"
>
</Button>
</LinearLayout>
</LinearLayout>
The MainActivity looks as follows and the HomePage.xml is also below
public class MainActivity extends ActionBarActivity
{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GetButtonClicked(5);
setContentView(R.layout.activity_main);
}
public void GetButtonClicked(int position)
{
// update the main content by replacing fragments
Fragment fragment = null;
switch (position){
case 0:
fragment= new FirstPageFragment();
break;
default:
fragment = new FirstPageFragment();
break;
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
}
public void ClickHomePage(View view){
GetButtonClicked(0);
}
public void ClickClients(View view){
GetButtonClicked();
}
}
<FrameLayout 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" tools:context="com.test.FirstPageFragment" android:background="#drawable/theme">
</FrameLayout>
This is the FirstPage
public class FirstPageFragment extends Fragment {
public FirstPageFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_first_page, container, false);
}
}

Use ralative layout insted of linear.

Make a different layout for bottom buttons, and then at the last of your container layout use this:
<include android:id="#+id/bottomLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
layout="#layout/bottom_buttons"/>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<Button
android:id="#+id/Main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickHomePage"
android:text="#string/Home" />
<Button
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickClients"
android:text="#string/Clients" >
</Button>
</LinearLayout>
Try this

Use RelativeLayout with android:layout_alignParentBottom="true" step by step guide is available here.
Your skeleton for layout should look like this
<RelativeLayout
<LinearLayout android:layout_alignParentBottom="true">
<Button
<Button
</LinearLayout>
</RelativeLayout>
Final Layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
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:layout_alignParentBottom="true"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="#+id/Main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickHomePage"
android:text="Home" />
<Button
android:layout_marginLeft="30dp"
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickClients"
android:text="Clients" >
</Button>
</LinearLayout>

The issue was that I did not include the container in another layout...
<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"
tools:context="com.test.MainPageActivityActivity">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:id="#+id/container">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:layout_alignParentTop="#+id/container">
and insert buttons layout here....
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/Main"
android:onClick="ClickHomePage"
android:text= "#string/Home"
/>
