where I wrong, and how to solve this, I already google about this problem, but I got no clue.
error in sheetBehavior = BottomSheetBehavior.from(layoutBottomSheet);
thanks

Your parent layout is a ConstraintLayout not a CoordinatorLayout

Please take look at my openUpFragmentById() method. What I want to do is when I click buttons on activity_main.xml, I want to inflate one of my fragments and fill up the whole activity_main and not show the original content.
I understand that the main purpose of fragment is to divide, or split activities, but I am wondering if I can replace (or change) all original contents in activity_main.xml with the contents in one of my fragments (I know that a fragment need a viewGroup in activity_main.xml (in my case) to inflate).
Besides, if it can`t, should I have additional activities to deal with this?
If it can, please provide me useful links or advice. Thanks in advance.

I don't see your fragment xml but i face this problem and i think you must set background to your fragment xml parent layout
For example :
<LinearLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragmentParent"
android:background="#android:color/white"
>
<!--your fragment views-->
</LinearLayout>

Clash Of Clan like NavigationView Pull Arrow

I want to create a custom view which stays visible while side drawer is closed, but by pulling that, the drawer will slide.
I had seen like this in very popular game Clash Of Clan like shown in below images:
Now I wonder if there is any way to achieve same by using DrawerLayout and NavigationView?

Finally I achieved this by adding addDrawerListener and translating the HANDLE accordingly.
Here is my ACTIVITY:
import android.os.Bundle;
import android.support.design.widget.NavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
/**
* #author Meet Vora
*/
public class PullSliderActivity extends AppCompatActivity {
private DrawerLayout drawerLayout;
private View viewPuller;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pull_slider);
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
viewPuller = findViewById(R.id.viewPuller);
drawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
viewPuller.setTranslationX(drawerView.getX() + drawerView.getWidth());
}
#Override
public void onDrawerOpened(View drawerView) {
}
#Override
public void onDrawerClosed(View drawerView) {
}
#Override
public void onDrawerStateChanged(int newState) {
}
});
}
}
Here is LAYOUT 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"

How to properly combine NavigationView and BottomNavigationView

I need to use both elements and this is what I have at the moment:
<?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.support.v4.widget.DrawerLayout xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/colorAccent"
app:menu="#menu/menu_bottom" />
</RelativeLayout>
My problem here is that the BottomNavigationView is in front of the NavigationView, which should not be the case (I'm talking about the y-index). I also tried using a CoordinatorLayout instead, but then the BottomNavigationView is stuck at the display's top.

I would simply use DrawerLayout as the root element and inside the DrawerLayout you can put a layout for containing the main screen and a NavigationView for the menu. After you can put the BottomNavigationView into the main layout.
<android.support.v4.widget.DrawerLayout xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include layout="#layout/maincontent"/>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
maincontent.xml
<FrameLayout..>
...
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/colorAccent"
app:menu="#menu/menu_bottom" />
</FrameLayout>

Here this code runs perfectly for me
nav_header_home.xml

Make Drawer Navigation Menu Item Open new activity when clicked

I'm new to android app development and am trying to build an app. I have successfully built my navigation drawer but I want the menu items to open another activity when clicked. I have tried various answers on SO but my app seems to crash each time i run my app after applying any of the answers. Please what could be the cause of this.

In your menu.xml you have added this line android:onClick="settings". remove that line or add the following code to your MainActivity.java
public boolean settings(MenuItem item) {
// actions
return true;
}
