Adding Two containers to main

Good day
I am new to android development and I am trying to add 2 containers for fragments in the main xml file, that will each use half of the screen in landscape, but everything I try does not work, please help.
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.newProject.MainActivity">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="221dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<FrameLayout
android:id="#+id/fragments_container"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
thank you!

I hope this will work for you
For landscape mode
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="2"
tools:context=".MainActivity">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<FrameLayout
android:id="#+id/fragments_container1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>

In xml add
<LinearLayout
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"
android:paddingBottom="20dp"
android:paddingLeft="20dp"
android:orientation="vertical"
android:paddingRight="20dp"
android:paddingTop="20dp"
android:weightSum="2"
tools:context=".MainActivity" >
<FrameLayout
android:id="#+id/frame1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"></FrameLayout>
<FrameLayout
android:id="#+id/frame2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"></FrameLayout>
</LinearLayout>
in activity class:
public void loadFragments(){
Fragment1 fragment1 = new Fragment1();
Fragment2 fragment2 = new Fragment2();
loadFragment(this,fragment1);
loadFragmentTwo(this,fragment2);
}
public static void loadFragment(AppCompatActivity activity, Fragment newFragment) {
activity.getSupportFragmentManager().beginTransaction().replace(R.id.frame1, newFragment, getTagForFragment(newFragment)).commitAllowingStateLoss();
}
public static void loadFragmentTwo(AppCompatActivity activity, Fragment newFragment) {
activity.getSupportFragmentManager().beginTransaction().replace(R.id.frame2, newFragment, getTagForFragment(newFragment)).commitAllowingStateLoss();
}
public static String getTagForFragment(Fragment fragment) {
Log.d("fragment name", "fragment name " + fragment.getClass().getSimpleName());
return fragment.getClass().getSimpleName();
}

Try this xml code:
<android.support.constraint.ConstraintLayout
android:id="#+id/main_content"
android:layout_height="match_parent"
android:layout_width="match_parent">
<android.support.constraint.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.5" />
<FrameLayout
android:id="#+id/frameLayout2"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/guideline"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
<FrameLayout
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/frameLayout2"/>
</android.support.constraint.ConstraintLayout>

onClick listener cannot find one of my button fragments. Crashes when initializing button

So when I launch my app it just crashes because the button in my first fragment class cannot be found for some odd reason.
When I removed the
case R.id.button_accept : the program ran fine, so I was thinking it's most likely something I did with the XML in the register_user_fragment. So is there a specific way I need to call the button because there are multiple layouts in one class?
Here's the error.
Caused by: java.lang.IllegalStateException: Required view 'button_accept' with ID 2131296297 for field 'button_accept' was not found. If this view is optional add '#Nullable' (fields) or '#Optional' (methods) annotation.
Here's my baseactivity
public class BaseActivity extends AppCompatActivity implements View.OnClickListener {
//Fragments
Fragment usernameFragment;
Fragment passwordFragment;
//
FragmentManager fragmentManager;
#BindView(R.id.button_login)
Button button_login;
#BindView(R.id.button_accept) //CRASHES HERE.
Button button_accept;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//check if user is logged in or not
setContentView(R.layout.activity_login);
ButterKnife.bind(this);
usernameFragment = new UsernameFragment();
passwordFragment = new PasswordFragment();
fragmentManager = getFragmentManager();
button_login.setOnClickListener(this);
button_accept.setOnClickListener(this);
//setcontentview register page or whatever use is logged into
}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.button_login :
Toast.makeText(this, "testds", Toast.LENGTH_SHORT).show();
fragmentManager.beginTransaction()
.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
.replace(R.id.content_login, usernameFragment)
.commit();
break;
case R.id.button_accept :
fragmentManager.beginTransaction()
.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
.replace(R.id.register_user_fragment, passwordFragment)
.commit();
break;
}
}

Because the "button_accept" is in your fragment layout , not in your activity layout :).
Your binding a UI component that doesn't exist on your activity layout.

You just made your layout mixed. just remove the Button accept_button from frame layout .
The problem is here you have button in a layout parent in which you are placing fragment dynamically. so remove the button to out side or to upper parent and out side the fragment container.

BlurView library has no effect on the screen

I tried to use Dimezis's BlurView library to create a blur effect on android, but it hasn't worked at all.
I followed all the directions, but still it hasn't had any effect.
Here is the main activity layout that I inserted the BlurView layout xml into:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/mainRoot"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.mistplay.mistplay.MainActivity">
<eightbitlab.com.blurview.BlurView
android:id="#+id/blurView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:blurOverlayColor="#78ffffff">
<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.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<include layout="#layout/content_main" />
</eightbitlab.com.blurview.BlurView>
</android.support.design.widget.CoordinatorLayout>
And here is the code where I attempted to blur the screen in MainActivity:
#Override
protected void onResume() {
super.onResume();
updateBalanceandCheckTutorial();
if (UserManager.getInstance().getShouldShowTutorial()) {
BlurView blurView = (BlurView) findViewById(R.id.blurView);
final View decorView = getWindow().getDecorView();
final ViewGroup rootView = (ViewGroup) findViewById(R.id.mainRoot);
final Drawable windowBackground = decorView.getBackground();
blurView.setupWith(rootView)
.windowBackground(windowBackground)
.blurAlgorithm(new SupportRenderScriptBlur(this))
.blurRadius(10);
}
}
If anyone could tell me what I'm doing wrong that would be very helpful.
Thanks in advance!

Android Collapsing Toolbar was not hiding other element while collapsed

I have a layout on Android support design collapsing toolbar which contains the TextView but when I collapse my toolbar. some TextView showing with toolbar title.
I want to hide every other things rather than toolbar and title.
Here is my layout.
<android.support.design.widget.AppBarLayout
android:id="#+id/MyAppbar"
android:layout_width="match_parent"
android:layout_height="256sp"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:background="#ff009688"
app:contentScrim="#color/colorPrimary"
app:expandedTitleMarginTop="100sp"
app:expandedTitleGravity="center|bottom"
android:fitsSystemWindows="true">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
app:srcCompat="#drawable/bgimg"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="#+id/MyToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
<RelativeLayout
android:layout_width="match_parent"
app:layout_anchor="#+id/MyAppbar"
android:layout_height="match_parent">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/profile_image"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="#drawable/studentprofile"
app:civ_border_width="2dp"
app:civ_border_color="#0adcf4"
android:layout_marginTop="58dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<TextView
android:id="#+id/branch"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Branch: "
android:textColor="#color/textColorPrimary"
android:textSize="14sp"
android:layout_marginBottom="20sp"
android:layout_alignParentBottom="true"
android:layout_centerInParent="true" />
</RelativeLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
And my java code is...
collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapse_toolbar);
collapsingToolbar.setTitle(name);
collapsingToolbar.setExpandedTitleTextAppearance(R.style.expandedappbar);
collapsingToolbar.setCollapsedTitleTextAppearance(R.style.collapsedappbar);
final ImageView profile=(ImageView)findViewById(R.id.profile_image);
Picasso.with(this)
.load(photo_url)
.placeholder(R.drawable.studentprofile)
.networkPolicy(NetworkPolicy.NO_CACHE)
.into(new Target() {
#Override
public void onBitmapLoaded (final Bitmap bitmap, Picasso.LoadedFrom from){
/* Save the bitmap or do something with it here */
Palette.from(bitmap).generate(new Palette.PaletteAsyncListener() {
#Override
public void onGenerated(Palette palette) {
collapsingToolbar.setContentScrimColor(palette.getMutedColor(ContextCompat.getColor(context,R.color.colorPrimary)));
collapsingToolbar.setStatusBarScrimColor(palette.getMutedColor(ContextCompat.getColor(context,R.color.colorPrimaryDark)));
}
});
//Set it in the ImageView
profile.setImageBitmap(bitmap);
}
#Override
public void onBitmapFailed(Drawable errorDrawable) {
}
#Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
});

Since I resolve my problem myself I'm posting this answer so it will helpfull for others .
CollapsingToolBar extends FrameLayout so any xml tag written after another tag will be layered as top of parent. My RelativeLayout is written after the Toolbar thats why Relative Layout elements are showing on Toolbar after CollapsingToolbar collapsed.
just putting RelativeLayout before the Toolbar will hides the element after toolbar collapsed.

app:expandedTitleMarginTop="100sp"
app:expandedTitleGravity="center|bottom"
android:fitsSystemWindows="true">

app:civ_border_width="2dp"
app:civ_border_color="#0adcf4"
android:layout_marginTop="58dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<TextView
android:id="#+id/branch"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Branch: "
android:textColor="#color/textColorPrimary"
android:textSize="14sp"
android:layout_marginBottom="20sp"
android:layout_alignParentBottom="true"
android:layout_centerInParent="true" />
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/MyToolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>

try this:
change your CollapsingToolbarLayout layout attribute:
use:
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
instead of
app:layout_scrollFlags="scroll|exitUntilCollapsed"
and add this attribute to the toolbar component
android:minHeight="?attr/actionBarSize"
Explanation:
Assuming enterAlways is declared and you have specified a minHeight, you can also specify enterAlwaysCollapsed. When this setting is used, your view will only appear at this minimum height. Only when scrolling reaches to the top will the view expand to its full height:

Android - fragments don't show

I created one acivity and a few fragments. I try to show one of them after start-up but I see empty screen, without fragments (but with NavigationDrawer)
What do I do wrong?
I have no idea where my mistake is.
Thank you!

first you should add fragment :
FragmentManager fm=getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add([FRAGMENT],[STRING TAG]);
ft.commit();
