Fix botttom navigation bar keep expanding when its fragment contain Coordinator layout

I have bottom navigation bar activity with a fragment on top of it.
1 out of 3 menus that I have a fragment that uses Coordinator layout as its parent with App bar layout and collapsing toolbar. another menu works fine with Relative layout parent, but the fragment that has Coordinator layout doesn't work pretty well and make the bottom navigation bar expand its height by itself. Here I'm providing my Code and some screenshots. Thankyou
Here is the code of my fragment layout

}
This is how my error looks like
Here is a screenshot of my error when I select profile tab
it pooped out when I choose profile bar
Thank you :)

please try removing this line from your XML
`android:fitsSystemWindows="true"
because it sets the padding of the View to ensure the contents don’t overlay the system windows.

incomprehensible behavior of attribute app:elevation

I wonder why such a strange behavior in the app attribute: elevation = "0dp" and how to solve the problem. I use the androidx library. The toolbar is transparent. Shadow remains. When I write an app: elevation = "0dp", the shadow disappears, but the toolbar buttons, including the "back" buttons, stop responding.
I tried to solve it in other ways: android: elevation = "0dp"
programmatically set getSupportActionBar (). setElevation (0); Does not help.

Try the below code snippet instead of toolbar.setNavigationOnClickListener
#Override public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == android.R.id.home){
getActivity().onBackPressed();
}
return super.onOptionsItemSelected(item);
}
hope this will solve your problem.
thanks

This is just because you have used FrameLayout as a parent - and also removed elevation from AppBarLayout, and due to this, Your ScrollView is overlapping your AppBarLayout as it is written below AppBarLayout. change your root to something else, for eg.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Nested LinearLayout doesn't work in Android

I am trying to make layout like in the picture. Project picture I can only link it because I am new. When I run the code with just one LinearLayout it works fine. But when I make nested linear layout it shows an only white screen. And there are no errors. The code adds a score to teams according to their throw s.Thank you.
Java code:
public class MainActivity extends AppCompatActivity {
int scorea=0;
int scoreb=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void displayforpointb3(View view){
TextView scoreView=(TextView)findViewById(R.id.team_b_score);
scoreb+=3;
scoreView.setText(""+scoreb);
}
public void displayforpointb2(View view){

First of all you should define your TextView as a private attributes in your class as follows
private TextView scoreViewA;
private TextView scoreViewB;
Then in your onCreate() method, you should find the view of those TextView as follows
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
scoreViewA = findViewById(R.id.team_a_score);
scoreViewB = findViewById(R.id.team_b_score);
}
Then in your onClick methods, you should update those TextView
public void displayforpointb3(View view){
scoreb+=3;
scoreViewB.setText(""+scoreb);
}
public void displayforpointb2(View view){
scoreb+=2; //You had scoreb+=3 I changed it to 2
scoreViewB.setText(""+scoreb);
}
public void displayforfreethrowb(View view){
scoreb++;
scoreViewB.setText(""+scoreb);
}
public void displayforpoint3(View view){
scorea+=3;
scoreViewA.setText(""+scorea);
}
public void displayforpoint2(View view){
scorea+=2;
scoreViewA.setText(""+scorea);
}
public void displayforfreethrow(View view){
scorea++;
scoreViewA.setText(""+scorea);
}
Also I see something wrong in your activity_main.xml I guess is a misstype
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:text="#string/point2"
android:layout_weight="1"/> <--- Remove this "/>"
android:onClick="displayforpointb2"/>
Happy coding

Problem
The orientation of the root LinearLayout is horizontal. This results in child views appearing to the right of the Toolbar instead of underneath it.
Solution
Make the root LinearLayout vertical and wrap the two inner view groups in a horizontal 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">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<!-- Team A -->
<LinearLayout
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- Text & Buttons -->
</LinearLayout>
<!-- Team B -->
<LinearLayout
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- Text & Buttons -->
</LinearLayout>
</LinearLayout>
</LinearLayout>
It's not pretty, but it gets the job done. Consider using ConstraintLayout as an alternative to nested view groups if you encounter any performance issues.

Action Buttons do not cover the entire Toolbar

I have used a Toolbar to display four action buttons. When I inflate the toolbar with menu, the action buttons are displayed towards one side as shown in the picture :
How can I make these action buttons cover the entire toolbar?
This is the code for the Activity :
public class ResultActivity extends FragmentActivity {
final int TAB_NUM = 2;
private ViewPager mViewPager;
private PagerAdapter mPagerAdapter;
private Toolbar mResultToolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_result);
mResultToolbar = (Toolbar) findViewById(R.id.result_toolbar);
mResultToolbar.inflateMenu(R.menu.result_menu);
mResultToolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.camera_action :
Intent cameraIntent = new Intent(getApplicationContext(),CameraActivity.class);
startActivity(cameraIntent);
break;
case R.id.gallery_action :
Intent intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 0);
break;
case R.id.profile_action :
Toast.makeText(getApplicationContext(),"Profile",Toast.LENGTH_SHORT).show();
break;
case R.id.slide_up_action :
Toast.makeText(getApplicationContext(),"Slider",Toast.LENGTH_SHORT).show();
break;
}
return true;
}
});
mViewPager = (ViewPager)findViewById(R.id.result_view_pager);
mPagerAdapter = new ResultViewPagerAdapter(getSupportFragmentManager());
mViewPager.setAdapter(mPagerAdapter);
mViewPager.setPageTransformer(true, new DepthPageTransformer());
}
}
This is the XML :
<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:layout_marginLeft="#dimen/activity_margin_horizontal"
android:layout_marginRight="#dimen/activity_margin_horizontal"
android:background="#color/app_background">
<android.support.v4.view.ViewPager
android:id="#+id/result_view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/result_toolbar"
android:layout_alignParentTop="true"
android:background="#color/colorAccent">
<android.support.v4.view.PagerTabStrip
android:id="#+id/result_page_tab_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#color/instagram_background" />
</android.support.v4.view.ViewPager>
<android.support.v7.widget.Toolbar
android:id="#id/result_toolbar"
android:layout_width="match_parent"
android:layout_height="#dimen/toolbar_height"
android:layout_alignParentBottom="true"
android:background="#color/default_line_indicator_selected_color"
android:elevation="#dimen/toolbar_elevation">
</android.support.v7.widget.Toolbar>
</RelativeLayout>

You can add LinearLayout to toolbar with parameters
<LinearLayout android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:orientation="horizontaly"
android:weightSum="4"> </LinearLayout>
then for buttons
<Button android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
and every button will take 1/4 of toolbar space.
so to sum up, inside toolbar you will have:
<LinearLayout android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:orientation="horizontaly"
android:weightSum="4">
<Button android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
<Button android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
<Button android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
<Button android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
</LinearLayout>
I wrote it from head, so I not tested this code, but I hope it will be helpful for you.

If you have only four options for menu then you can think of not using Toolbar . Instead you can use a LinearLayout directly in AppBarlayout as it can hold other views then toolbar too.
Like
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/app_background">
<LinearLayout
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
android:orientation="horizontaly"
android:weightSum="4">
<Button
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
<Button
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
<Button
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
<Button
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"></Button>
</LinearLayout>
</android.support.design.widget.AppBarLayout>
I used the same layout of MyWay. Thanks MyWay.

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tv_nav_name"
android:textStyle="bold"
android:typeface="sans"
android:textColor="#ffffff"
android:gravity="right"
android:layout_gravity="right"
android:text="رخداد جدید"
android:paddingBottom="5dp"
android:textSize="#dimen/body"
/>
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:typeface="sans"
android:textColor="#ffffff"
android:id="#+id/tv_nav_phone"
android:layout_alignParentLeft="true"
android:text="0370077315"
/>
</RelativeLayout>
</LinearLayout>
then i include it as child of NavigationView and For menu item i use RecyclerView to show menu and icon so my NavigationView is
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="spydroid.ir.dorobar.Activities.SearchActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_search" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView android:id="#+id/nav_view"
android:layout_width="fill_parent" android:layout_height="match_parent"
android:layout_gravity="right" android:fitsSystemWindows="true"
android:layout_marginLeft="#dimen/nav_margin"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<include layout="#layout/nav_header_main" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/drawer_slidermenu"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_marginTop="16dp"/>
</RelativeLayout>
</LinearLayout>
</android.support.design.widget.NavigationView>
just you have to remember put your NavigationView in DrawerLayout
then i create layout for menu item with ImageView and TextView this layout and this name is card_drawer_item.xml and its code is here
<?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="48dp">
<ImageView
android:id="#+id/drawer_icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:src="#drawable/ic_about"
android:layout_centerVertical="true" />
<TextView
android:id="#+id/drawer_text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toLeftOf="#id/drawer_icon"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:typeface="sans"
android:paddingRight="40dp"/>
</RelativeLayout>
then i create ViewHolder folder for this layout.
public class DrawerItemHolder extends RecyclerView.ViewHolder {
public ImageView itemIcon;
public TextView itemText;
public DrawerItemHolder(View itemView) {
super(itemView);
itemIcon= (ImageView) itemView.findViewById(R.id.drawer_icon);
itemText= (TextView) itemView.findViewById(R.id.drawer_text);
}
}
now i define text of menu items as string array and array that contains menu icons in menu in strings.xml
<string-array name="drawer_items">
<item>setting</item>
<item>add record</item>
<item>ads</item>
<item>about</item>
<item>call</item>
<item>help</item>
<item>privacy</item>
</string-array>
<array name="drawers_icons">
<item>#drawable/ic_action_settings</item>
<item>#drawable/ic_plus</item>
<item>#drawable/ic_ads</item>
<item>#drawable/ic_about</item>
<item>#drawable/ic_phone</item>
<item>#drawable/ic_help</item>
<item>#drawable/ic_policy</item>
</array>
then we just need an Adapter like this
public class DrawerItemAdapter extends RecyclerView.Adapter<DrawerItemHolder> {
// slide menu items
private List<DrawerItem> items;
private List<Integer> drawerIcons;
public DrawerItemAdapter(List<DrawerItem> items) {
super();
this.items = items;
}
#Override
public DrawerItemHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.
from(parent.getContext()).
inflate(R.layout.card_drawer_item, parent, false);
return new DrawerItemHolder(itemView);
}
#Override
public void onBindViewHolder(DrawerItemHolder holder, int position) {
holder.itemIcon.setImageResource(items.get(position).getIconId());
holder.itemText.setText(items.get(position).getText());
}
#Override
public int getItemCount() {
return items.size();
}
}
every thing is ok .. just now we have to set NavigationView in Activity.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
recList = (RecyclerView) findViewById(R.id.drawer_slidermenu);
recList.setHasFixedSize(true);
LinearLayoutManager llm = new LinearLayoutManager(this);
llm.setOrientation(LinearLayoutManager.VERTICAL);
recList.setLayoutManager(llm);
String []itemsTitle=getResources().getStringArray(R.array.drawer_items);
TypedArray icons=getResources().obtainTypedArray(R.array.drawers_icons);
List<DrawerItem>drawerItems= new ArrayList<DrawerItem>();
for(int i=0;i<itemsTitle.length;i++){
drawerItems.add(new DrawerItem(icons.getResourceId(i,-1),itemsTitle[i]));
}
DrawerItemAdapter ad= new DrawerItemAdapter(drawerItems);
recList.setAdapter(ad);
}
#Override
public void onBackPressed() {
if (drawer.isDrawerOpen(GravityCompat.END)) {
drawer.closeDrawer(GravityCompat.END);
return;
}
super.onBackPressed();
}
