An activity has an icon to choose Image from Files. After choosing the Image, The next activity page opens which has A button and an ImageView where the selected iimage should be displayed.
I can choose the Image but it does not show on ImageView.
I has tried Bitmap and it doesnt work. If I try to resize map and then run app, after choosing the image the app closes.
Below is the XML and Java of the activity
<?xml version="1.0" encoding="utf-8"?>

Matrix matrix = new Matrix();
matrix.postRotate(angle);
return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true);
}
}
I need the selected Image to be shown in the ImageView and when I click the Edit button the Image should be passed to the next activity too.

I am working on Android with a Lottie animation. I implemented a shared transition on Lottie from one activity to another activity. But this is not Working. What am I doing wrong in my setExitSharedElementCallback method?

I have an android application and i want to display database data in one of the activity in a listview. I already managed to display it in a listview on a fragment, but now i want to apply the same process to an activity.
I already tried to take the code i used to display data on my fragment, and use it for my activity, but didn't work even after making some change, and i'm still getting an error on #Override.
Here is my activity code :
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

String CONTENU_ANG_DATE;
HashMap<String,String> user;
ListView CDCANGList;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_admin_evenement3);
Date = (TextView) findViewById(R.id.Date);
Intent incomingIntent = getIntent();
String date = incomingIntent.getStringExtra("date");
Date.setText(date);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.fragment_cdc_ang, container, false);
CDCANGList = rootView.findViewById(R.id.CDCANGList);
SchoolDB = new DBHelper(AdminEvenementActivity3.this);
SQLiteDatabase db = SchoolDB.getReadableDatabase();
ArrayList<HashMap<String, String>> userList = new ArrayList<>();
Cursor view = db.rawQuery("SELECT CONTENU_ANGLAIS_DATE, CONTENU_ANGLAIS FROM CONTENU_COURS_ANGLAIS", null);
if (view.moveToFirst()){
do {
// Passing values
user = new HashMap<>();
CONTENU_ANG = view.getString(view.getColumnIndex("CONTENU_ANGLAIS"));
CONTENU_ANG_DATE = view.getString(view.getColumnIndex("CONTENU_ANGLAIS_DATE"));
user.put("Contenu",CONTENU_ANG);
user.put("Date",CONTENU_ANG_DATE);
userList.add(user);
} while(view.moveToNext());

CDCANGList.setAdapter(adapter);
}
view.close();
db.close();
return rootView;

Here is my layout holding the listview :

I'm expecting each row of the table to display in the listview of my activity. I'm getting the following error message caused by the "#Override" : "error: method does not override or implement a method from a supertype".
'onCreateView() method is only for fragment it cannot be override in activity.'
put you all the code in onCreate() method of your activity. it will be working pretty fine Thanks
if you feel any other problem please discuss
Thanks you a lot for your answer! I did the modification, but now i'm having some troubles on my layout inflater and my retur rootView. Any ideas how i could correct this? See my code below.

I am developing online store application, i used bottom navigation menu and fragments to separate the pages of my online store , in my main fragment i have one scrollview that contains one image slider and two horizontal recycler views that used to show newest and special products.
every thing id good but
my really strange problem is that when i run application in my android phone the scrollview has really really bad performance, it scrolls really slowly and not smoothly.
i tried many ways to solve this problem ( but unfortunately none of them could solve my problem ) :
- i tried to remove image slider library
- i taught maybe images and bitmaps are the main cause of this bad performance but after i removed all images nothing changed !!!

the problem was because of 2 lines that i was added to the manifest to prevent from android out of memory exception ...
remove these two lines and every thing well be ok :
android:largeHeap="true"
android:hardwareAccelerated="false"
i hope this answer going to help you ...
do the height of relative layout ="wrap_content" instead of match parent , also of scrollview.
When I scroll past an item and come back to it, it changes it's position until I click on it, then it will correctly align itself. How can I solve this. Sorry I am still at the start of the project so my code is a bit messy.
This is my code:

There is a good link on how to load large Bitmaps efficiently, so that you don't get an OutOfMemory-Error.
Here ist the link: http://developer.android.com/training/displaying-bitmaps/load-bitmap.html
But my problem is, that I am a very newbie and I don't know how to understand the link. Could you please help me and modify my codes?
XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/imageView2"
android:layout_width="250dp"
android:layout_height="250dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:onClick="Menue"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="200dp"
android:layout_height="100"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:src="#drawable/pfeilrechts"
android:onClick="Picture2"/>
