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>

Android: Order of addition of fragments

I have this code:
findViewById(R.id.button2).setOnClickListener(new View.OnClickListener()
{
//Se aggiungo un fragment A al container X e aggiungo il fragment B allo stesso container, il fragment B andrà sopra
//il fragment A
#Override
public void onClick(View v)
{
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
if(ko==0)
{
MyFragment fragment = MyFragment.createFragment(0);
fragmentTransaction.add(R.id.formazione3,fragment);
ko++;
}
else if(ko==1)
{
MyFragment fragment = MyFragment.createFragment(1);
fragmentTransaction.add(R.id.formazione2,fragment);
ko++;
}
else if(ko==2)
{
MyFragment fragment = MyFragment.createFragment(2);
fragmentTransaction.add(R.id.moduli2,fragment);
ko++;
}
else if(ko==3)
{
MyFragment fragment = MyFragment.createFragment(1);
fragmentTransaction.add(R.id.moduli5,fragment);
}
fragmentTransaction.commit();
}
});
Well, I'm experiencing the order of addition of fragments. I have 4 fragments and I don't understand why some fragments, when I add them, go under the bigger fragment, while other ones go on the bigger fragment in their container.
formazione3>formazione2 (formazione2 is contained in formazione3)
moduli2>moduli5 (moduli5 is contained in moduli2, moduli2 is contained in part in formazione3)
When I add the second fragment, it doesn't show, I think that it goes under the previous fragment, so it goes under the bigger. When I add the third fragment, it goes in part under the first fragment, the first is bigger. When I add the fourth fragment, it goes on the third, but the third is bigger than the fourth and above all the the fourth is contained in the third. How does it work? I don't understand at all!

Your parent layout is a RelativeLayout , the default behavior for this layout is that first child view is under the last child view.
In your xml this child :
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="51dp"
android:layout_height="match_parent"
android:id="#+id/moduli3">
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/formazione3">
</RelativeLayout>
</LinearLayout>
is under this child view :
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="71dp"
android:layout_height="match_parent"
android:id="#+id/moduli2">
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/formazione2">
</RelativeLayout>
</LinearLayout>
so when the views are inflating , this is the opposite formazione3 is over formazione2.
Moreover your LinearLayout have these attributes :
android:layout_width="match_parent"
android:layout_height="match_parent"
so they take all the place available.
Try to set fixe size in dp instead of match_parent to see what's really happen.
Hope this helps.
Sorry for my poor english.

Java Android : onItemLongClick for listView doesn't respond

I'm developing an Android application.
I want to display a list of contacts (using listview) and I want to add 2 alerts dialogs: one by onItemClickListener and the other by onItemLongClickListener.
But the onItemLongClickListener is never called, just the onItemClickListener.
I already did it for another application, but here it doesn't work and I don't find why :/
My code:
public class ContactActivity extends AppCompatActivity {
private ListView listView;
private ContactAdapter adapter; //my adapter
private ArrayList<Contact> contacts; //my list of contacts
//...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);
//here i init my "listView" and "contacts"
adapter = new ContactAdapter(this, contacts);
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("longClick", "ok");
return true;
}
});
listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> a, View v, final int position, long id) {
//here i display a Dialog
}
});
//some code
So, when I "simple click" on an item of the list, the dialog appears (ok).
But when I "long click" on an item of the list, the dialog appears and i don't see the Log...
(The item that i use for my ListView got just 2 EditText)
PS: the XML where my listView is shown
<?xml version="1.0" encoding="utf-8"?>

SOLUTION
I had a onSwipeRight() on my listener, it blocked the onItemLongClickListener
here is the code that was blocking the listener
listView.setOnTouchListener(new OnSwipeTouchListener(getApplicationContext()) {
public void onSwipeRight(){
//some code
}
});
Big thanks to ddb for his time :)

why are you passing a new AdapterView.OnItemLongClickListener?
just do like this below instead
listView.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("longClick", "ok");
return true;
}
});

Do not set listView.setLongClickable(true);, listView.setClickable(true); in your java.
Neither
android:longClickable="true"
android:clickable="true"
Inside your xml

I want to inflate an xml file into MainActivity

I have an xml file named " Editt.xml ",I want to inflate #+id/myEditText into MainActivity every time I click an Button from the activty_main named " #+id/Button01 "
" Editt.xml " is this :
<LinearLayout

Android tabhost issue...code included

I am getting the following error when I try to launch an activity containing a tabhost.

I think the 3 linear layouts, jobDetail1->3 should be within the FrameLayout xml element. The point of the FrameLayout is that all of the views are on top of each other, and thus the tab manager can decide which view to show.

I think you're getting this error because you are not including the LinearLayout inside the FrameLayout, besides I think you need to put some element view inside the LinearLayout's.
Something like this
<?xml version="1.0" encoding="utf-8"?>
