if (player!=null && player.isPlaying())
player.stop();
player=MediaPlayer.create(this,ids[i]);
player.start();
}
#Override
public void onBackPressed ()
{
if (player != null)
player.stop();
super.onBackPressed();
}
#Override
public void onPause ()
{
if (player != null)
{
player.pause();
player.stop();
}
super.onPause();
}
}
To get the text of the clicked listener use this
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String currentText = parent.getItemAtPosition(position); // Assuming you've used only string
}
Another way to get the item clicked is to pass the position to Adapter and get the selected object from Adapter. Then you can use the selected object in any way you like.
Hope it helps

PLEASE HELP GUYS PLEASE
It took me three days to figure out what's the problem in my code. After knowing my mistake i am feeling very ashamed as well as happy that i figured, it out.
the mistake is in the adapter code,
in.putExtra(" videourl", post.getVideourl());
String ttr = in.getStringExtra("videourl");
the difference between above two code line is the, in first line there is space before the videourl and in the second line there is no space before videourl, and that's a problem. :-)
I'm trying to pass images from a Realtime Database Recycler View to another activity.

private void ClearAll(){
if(messagesList != null){
messagesList.clear();
if (recyclerAdapter !=null){
recyclerAdapter.notifyDataSetChanged();
}
}
messagesList = new ArrayList<Messages>();
}
}
This is the first activity layout
The activity I want the images to be displayed in.
package com.khumomashapa.notes.activities;
import androidx.annotation.NonNull;

import android.os.Bundle;
import android.widget.Button;

public class PreviewActivity extends AppCompatActivity {
private ImageView preview;
Button purchaseBtn;
Button downloadBtn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_preview);
preview = findViewById(R.id.ImagePreview);
purchaseBtn = findViewById(R.id.PurchaseBtn);
downloadBtn = findViewById(R.id.DownloadBtn);
String preview = getIntent().getStringExtra("images");
}
}
This is the second activities layout
As you can see there's no image showing up in the imageview.
This code does work. It does take the user to another activity, but it doesn't show the image that was clicked in the first activity and as you can see I have more than one image I want to show. The image that was clicked must be shown in the next activity.
So in short what I want to happen is:
Someone clicks an image e.g. Abduction, Blue Cinema etc.
Then the user is taken to another activity and is shown the image they clicked(Abduction or Blue Cinema etc).
Sorry if I sound redundant, but I've been stuck on this for awhile and the tutorials/posts I read before didn't help, because they don't use code that works with Firebase Realtime Database.
I am looking into using the viewHolder pattern for making my UI elements not get reset to the default when my listview is scrolled. After looking into it Im not sure how to go about this. Im not even sure if my existing code will even allow me to use viewHolder pattern. I am a beginner so please elaborate and do not skip the details. Thank you

I found this tutorial really helpful when learning to use the ViewHolder Pattern. It is pretty clear in explaining how to use it, but feel free to ask if you feel stuck.
When you are performing some change to any list Item we should call notifyDataSetChanged(),so that the listview gets updated.
Answer to your question:
call notifyDataSetChanged() in textview.onClickListener() method after updating the text.
Better to shift to RecyclerView, In this when we add new item we can just call notifyItemAdded(position) which will refresh only the view at that position but not the whole.
And when we update any item we can call notifyItemChanged(position).
How can I get String from my database and combine it with Image from my drawable folder. Help Please.
this is my main activity.
