I am setting text on textview but it's giving me NullPointerException
Here's my XML file.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

</androidx.cardview.widget.CardView>
</LinearLayout>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
This is my activity where I am setting text on TextView
public class ScoreActivity extends AppCompatActivity {
private TextView scoreQTv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_score);
scoreQTv = findViewById(R.id.scoreQTv);
//and finded all widgets using findviewByID ...
scoreQTv.setText("My Score 18");
}
I am unable to set text on my TextViews. How can I set text, and why am I getting this error?
When I check my layout file, I got 2 files with the same name. I think that's why this happens. I have 2 files like this:
activity_score.xml
activity_score.xml v21 written under the name.
This is my LogCat:

In Your Question You have 2 files with same name
1.activity_score.xml
2.activity_score.xml v21
So you can delete that xml layouts and make new activity:
Create New Activity named Anything You Want
and paste all xml code to that new Activity's xml layout
and all java code to that's new Activity java file
I thing Maybe it help you!

The app launches and runs well on Android 10 and upward. However, on Android 9 and lower, it keeps throwing this runtime exception that has kept me searching for days. Here is the stack trace:

I believe there must be a resource which Android >=10 ignores or automatically finds hence the exception is not thrown but lower versions shut down.
What I have done
I have created the "res/color/text_color_primary.xml". The error remains.
I have rebuilt and cleaned over and over.
I have tried to locate the resource file where the problem is being generated, can't find it.
I have tried several other ideas including this and this
EDITED
Here's a draft of the affected layout file:
<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"

Ok. So I finally found the problem by isolating each section of the layout file. The problem is actually from the Backdrop section, particularly, the layout that I included:
<include layout="#layout/backdrop"></include>
The backdrop.xml contains a View segment that takes a colour reference for the background:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<com.google.android.material.button.MaterialButton
style="#style/Widget.Shrine.Button.TextButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#F4D7D5"
android:id="#+id/fullscreen_button"
android:text="Livestream" />
<View
android:layout_width="56dp"
android:layout_height="1dp"
android:layout_margin="16dp"
android:background="?android:attr/textColorPrimary" />
</merge>
The android:background textColorPrimary is not accessible in Android 9 and lower, check statement by #azizbekian at Why does ?android:textColorPrimary get different values with different API versions?:
This means, that the value specified in the current theme's android:textColorPrimary would be applied. So, if you have declared a TextView in xml and have applied android:textColor="?android:textColorPrimary" to it, then this attribute would be fetched from the theme of the current context with which this layout is being inflated.
As it seems, Android 9 and lower does not reference the attrs.xml. Here's the section of the xml:
<!-- The most prominent text color. -->
<attr name="textColorPrimary" format="reference|color" />
<!-- Secondary text color. -->
<attr name="textColorSecondary" format="reference|color" />
<!-- Tertiary text color. -->
<attr name="textColorTertiary" format="reference|color" />
To solve the problem, I simply changed the View background to this:
<View
android:layout_width="56dp"
android:layout_height="1dp"
android:layout_margin="16dp"
android:background="#color/textColorPrimary" />
Now app is running fine.
I'm working on getting the Google Place API to appear within a CardView.
The particular code I'm looking at is from GitHub, seems to be working for everyone else but I don't understand why it's throwing me an error.
This is the error I am getting:

The main takeaway is that there is an Error inflating class android.fragment.app.FragmentContainerView and that the issue is at line 50 of the XML.
This is the XML:

So I guess there is something wrong with the FragmentContainerView? But i'm not getting any errors in the code and nothing is coming up on Google.
I feel like maybe something is outdated rather than outright incorrect but I haven't a clue.
Thanks for any input.
just try to define your startDestination in your navigation xml !
You should implement new androidx.fragment dependencies to use FragmentContainerView. It is already added since version 1.2.0. You can check here
implementation "androidx.fragment:fragment:1.2.5"
In my case, I had a Model which was used as arguments but I had not implemented Serializable and Parcelable implementaion.
This problem was created for me as well. The reason was two mistakes.
1.I did not add startDestination in nav graph .
2.I did not add #AndroidEntryPoint annotation in MainActivitey .
This error will only occur after you have added ProGuard & R8 to your project. To fix it, add the following two lines in proguard-rule.pro:
-keepnames class androidx.navigation.fragment.NavHostFragment
-keep class * extends androidx.fragment.app.Fragment{}
For me it was a typo within one of the fragments the navGraph, in the class path of the android:name attribute.. Adding a wrong path for the fragment class doesn't provide a compile time error, instead it raises android.view.InflateException...Error inflating class android.fragment.app.FragmentContainerView
So, make sure to have a correct packaging path for your fragments in android:name
<?xml version="1.0" encoding="utf-8"?>
<navigation 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/nav_graph.xml"
app:startDestination="#id/mainFragment">
<fragment
android:id="#+id/mainFragment"
android:name="com.example.android....MainFragment" // <<<< This must be a correct path
android:label="main_fragment"
</fragment>
</navigation>
If it is Due to Proguard Then add few lines
In proguard-rules.pro file
....
# for FragmentContainerView error
-keepnames class androidx.navigation.fragment.NavHostFragment
-keep class * extends androidx.fragment.app.Fragment{}
Your activity must be a child of FragmentActivity to use androidx.fragment.app.FragmentContainerView either you extend the FragmentActivity or the AppCompatActivity which is a child FragmentActivity class. It is recommended to extend the AppCompatActivity.
see: https://www.tutorialguruji.com/android/trying-to-use-navhostfragment-and-im-getting-an-error-error-inflating-class-androidx-fragment-app-fragmentcontainerview/
Probably after Refactor->Remove unused resources you can lost id from your androidx.fragment.app.FragmentContainerView - bring it back
In my case, despite the same error, reason was different.
However this info about adding some rules to proguard-rules.pro pointed me into the right direction. This, and some other clues in error log about problems with argument in navigation XML file.
Eventually I found that it was problem with using my own classes in argument. And I don't mean the class of argument, but the fact that this class also used some of my other classes. And it was enough to add rules for each of these other classes:
-keepnames class <MyClass>
...
If you have done all the solutions and still the problem stands maybe you should check if your fragment constructor is empty.
In my case I looked deeper inside my stacktrace and found this line: Caused by: java.lang.IllegalStateException: FragmentContainerView must have an android:id to add Fragment MyFragment. Giving it an id and specifying tools:layout fixed problem
I want to implement a BottomSheetBehavoir component to an activity screen, but when I want to initialize the component via BottomSheetBehavoir.from(view) the getLayoutParams() method throw a null pointer exception.
This is my init code in onCreate():
LinearLayout llBottomSheet = findViewById(R.id.bottom_sheet_live_tracking_list_container);
BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(llBottomSheet);
And this is my xml layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottom_sheet_live_tracking_list_container"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
app:behavior_hideable="false"
app:behavior_peekHeight="40dp"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="match_parent"
android:layout_height="40dp"
android:orientation="horizontal"
android:background="#drawable/rounded_corners_gray">
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="#string/show_more"
android:textColor="#color/white"
android:layout_gravity="center"
android:gravity="center"
android:layout_weight="1"
android:id="#+id/activity_live_tracking_show_more_tv" />
<ImageView

android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="0.1"
android:src="#drawable/ic_filter_list"

</LinearLayout>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/activity_live_tracking_position_list_rv"
android:layout_width="match_parent"
android:layout_height="match_parent" />
I include this layout in my root xml layout via the include tag.

As mentioned in the documentation BottomSheetBehaviour is deprecated. If you still want to use it, make sure it is child of a CoordinatorLayout as that is a prerequisite to use it according to the doc.
Would rather have added this answer as a comment, but not enough reputation...
So after I rest some days and go back to the problem I found the solution. For my LinearLayout, that throws the getLayoutParams() null pointer exception, I use the id from the bottom sheet xml that you can see in my post android:id="#+id/bottom_sheet_live_tracking_list_container". In my main layout there the parent is a CoordinatorLayout is include my bottom sheet layout like this:
<androidx.coordinatorlayout.widget.CoordinatorLayout 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:animateLayoutChanges="true">
... other stuff ....
<include
android:id="#+id/activity_live_tracking_bottom_sheet"
layout="#layout/bottom_sheet_live_tracking_list" />
Know I try the id from the include tag (android:id="#+id/activity_live_tracking_bottom_sheet") and it works. I can't give you an explanation why the other id that marked the LinearLayout directly returning null for getLayoutParams() method.
My xml file contains the code:
<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
android:id="#+id/bnve"
android:layout_gravity="bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/colorPrimary"
app:itemIconTint="#drawable/bottom_navigation_colors"
app:itemTextColor="#drawable/bottom_navigation_colors"
app:menu="#menu/bottom_nav_menu" />
My java file contains:
BottomNavigationViewEx bnve = (BottomNavigationViewEx)findViewById(R.id.bnve);
It runs perfectly on an android device.
But when I add the lines:
bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);
the app crashes with the error:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.bimsina.projectchautari/com.bimsina.projectchautari.MainActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Class java.lang.Object.getClass()' on a null object reference

Does someone have a solution?
Edit: Heres my whole xml and java file.
<?xml version="1.0" encoding="utf-8"?>
<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=".MainActivity">
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
android:id="#+id/bnve"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="#menu/bottom_menu"/>
</android.support.constraint.ConstraintLayout>
The java file is:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationViewEx bnve= findViewById(R.id.bnve);
bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);
}
}
This error comes from using different version of support library that is not compatible with the library.
hence for old version support lib 25 or 26 use
com.github.ittianyu:BottomNavigationViewEx:1.2.4
and for new com.android.support:design:28.0.0 use
com.github.ittianyu:BottomNavigationViewEx:2.0.2
This will solve the problem
I found a work around for the problem.I just wanted to remove the animation. Instead of using BottomNavigationViewEx,I used the regular BottomNavigationView and added the following line which removed the animation.
app:labelVisibilityMode="unlabeled"
It will remove the label and also disable the animation.
I'm using 2 phones for debuging and 1 phone is showing my activity fine and the other dose the error, how can I repair it + how can I handle it for another users to not have crashes?
the crash:

edit:
thanks for AndroidStudio decompiler I adding the done.xml that dose all the errors.

edit 2:
the layout xml out of the library:

its an error in your IntroActivity. InflateException: Binary XML file line #38: Error inflating class com.miz.introactivity.NextDoneButton
More than likely; this could be due to any LARGE images you are using and the device is simply out of memory to display it. Try resizing the image to make the size of it smaller
