I want to use databinding at the entrance to the navigation.
When I use fragment(android:name="NavHostFragment") in the activity, the program can run normally;
but when I use fragment in the activity (android:name="NavHostFragment") + databinding, the program will not run.
Please help me, I hope to use databinding at the entrance of the navigation, please tell me how to use it, thank you! !

You're calling setContentView twice, once with setContentView and a second time with DataBindingUtil.setContentView(). Instead, just use DataBindingUtil.setContentView(), which calls setContentView() itself internally:
public class MainActivity extends AppCompatActivity {
private ActivityMainBinding activityMainBinding;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
activityMainBinding = DataBindingUtil.setContentView(this,R.layout.activity_main);
}
}

I've been struggling on this the whole day and still can't make it work. In an existing Single Activity app, I'm trying to replace all fragment transactions by implementing the Navigation component.
I've already created a Navigation graph and included the FragmentContainerView as a child of the root ViewGroup as it was proposed in the official docs.
activity_main.xml
<FrameLayout
android:id="#+id/container"
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/appBarLayout">
<androidx.fragment.app.FragmentContainerView
android:id="#+id/main_content"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
app:defaultNavHost="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/appBarLayout"
app:navGraph="#navigation/nav_graph" />
</FrameLayout>
Now the problem that I'm currently facing is that the SharedViewModel which I am using through the whole app can't be instantiated in the BaseFragment anymore.
BaseFragment.kt
abstract class BaseFragment<E : ViewDataBinding, T : BaseViewModel> : Fragment() {
lateinit var viewModel: T
lateinit var dataBinding: E
abstract fun getLayoutResource(): Int
abstract fun getViewModelClass(): Class<T>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
activity?.let {
// java.lang.RuntimeException: Cannot create an instance of class SharedViewModel
viewModel = ViewModelProvider(it).get(getViewModelClass())
// viewModel = ViewModelProvider(getParentFragment()).get(getViewModelClass()) also doesn't work
}
}
...
}
BaseViewModel.kt
abstract class BaseViewModel : ViewModel(), LifecycleObserver
SharedViewModel.kt
abstract class SharedViewModel : BaseViewModel() {
...
}
SharedViewModelImpl.kt
class SharedViewModelImpl(private val repository: AppRepository) : SharedViewModel(){
...
}
I've read posts on SO and as well as Medium articles that recommend creating the SharedViewModel by using by navGraphViewModels like this
val viewModel: SharedViewModel by navGraphViewModels(R.id.navigation_graph)
but it seems that I still can't combine this approach with the generics that I already have.
My assumption is that the Navigation component can't deal with abstract classes.
How can I overcome this problem by keeping my existing app architecture? Many thanks in advance.

Whenever I assign an android:onClick attribute to an AutoCompleteTextView, my application immediately crashes upon loading the activity. I've tested AutoCompleteTextView without assigning an onClick method and it seems to work fine, as does assigning onClick to other views (including EditText, Spinners, TextViews, Buttons and ImageButtons). I've managed to narrow down the error to specifically to line 24 (setContentView(R.layout.activity_main)). Can anyone shed some light on this?

This looks like to be a bug in AutoCompleteTextView.
What happens:
Inflating the XML invokes AutoCompleteTextView constructor, and it invokes View constructor.
View constructor sees the onClick attribute and calls setOnClickListener().
AutoCompleteTextView has overridden setOnClickListener() which writes to an internal mPassThroughClickListener field. It is only initialized at the end of AutoCompleteTextView constructor, and this init code has not been run yet.
Reference
To work around it, remove the onClick attrtibute from your XML and call setOnClickListener() programmatically in your code.
I filed a bug about this in Android issue tracker.
I am trying to add a bottom navigation view of support library in my app. Here is the code below. I am getting error like
Caused by: android.view.InflateException: Binary XML file line #52: Binary XML file line #52: Error inflating class android.support.design.widget.BottomNavigationView
But my xml code is looking fine also. And the gradle dependency version of support and appcompat are also equal. I couldn't figure out the error. Can someone help me to figure out the issue?
XML code is
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:design="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/rl_container">
</RelativeLayout>
</LinearLayout>
<android.support.design.widget.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/bottom_navigation"
android:layout_alignParentBottom="true"
app:itemIconTint="#color/drawer_item"
app:itemBackground="#color/brand_black"
app:itemTextColor="#color/drawer_item"
app:menu="#menu/drawer"/>
</android.support.v4.widget.DrawerLayout>
And my java code is
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_menu);
// getSupportActionBar().setDisplayHomeAsUpEnabled(true);
///getSupportActionBar().setDisplayShowTitleEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
BnavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation);
SharedPreferences sP = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
String user = sP.getString("user", null);
sessionManager = SessionManager.getInstance(this);
if(user == null ) {
finish();
startActivity(new Intent(getApplicationContext(), Splash.class));
return;
}
BnavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
onDrawerMenuItemClicked(item);
return true;
}
});

I am trying to understand how fragments work, but i haven't had sucess so far.
This is only an example nothing usefull.
when i try to add a fragment to the layout I get always the same error.
I don't know what is missing
Fragment Class
package com.app.danieltavares.teste;
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class TestFragment extends Fragment{
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.testefrag,container,false);
}
}
ActivityClass
package com.app.danieltavares.teste;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Layout Fragment
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="diusdb"/>
</LinearLayout>
Layout that uses the fragments
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
