Android: Gridview not displayed in fragment

Good evening, i'm new in Android programming and i'm facing a problem in displaying a gridview in fragment.
I'm loading an inventory list in order to show if one item is checked or not.
I have loaded data in arraylist and i'm sure it is passed correctly to the fragment.
The problem is that the Gridadapter is trying to load only first item (for two times it seems) but the result is blank screen.
This is my fragment code
package testjava.pulsanti;
import android.os.Bundle;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.GridView;
import android.widget.TextView;
import java.lang.reflect.Array;
import java.util.ArrayList;
public class Fragment2 extends Fragment {
ArrayList<bancale> transactionList;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View myfragmentview = inflater.inflate(R.layout.fragment_2, container, false);
if (getArguments() != null) {
transactionList = (ArrayList<bancale>) getArguments().getSerializable("bancali");
for (int i = 0; i < transactionList.size(); i++) {
bancale banc = transactionList.get(i);
System.out.println(banc.numeroudm + " " + banc.statoInventario);
}
if (transactionList != null) {
GridView gridView = myfragmentview.findViewById(R.id.GridviewInv);
GridAdapterInv gridAdapter = new GridAdapterInv(this.getContext(), transactionList);
gridView.setAdapter(gridAdapter);
}
}
return myfragmentview ;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
#Override
public void onPause() {
super.onPause();
System.out.println("Fragment 2 paused");
// Fragment frag = new Fragment1();
// getParentFragmentManager().beginTransaction().replace(R.id.Viewpager,frag).commit();
}
}
and this is the GridAdapterCode
package testjava.pulsanti;
import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
public class GridAdapterInv extends BaseAdapter {
Context context;
ArrayList<bancale> bancali;
LayoutInflater inf;
public GridAdapterInv(Context context, ArrayList<bancale> bancali) {
this.bancali = bancali;
this.context = context;
inf = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return bancali.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View v, ViewGroup parent) {
ViewHolder holder;
if (v == null) {
v = inf.inflate(R.layout.elementogriglia_inv,null,false);
holder = new ViewHolder();
holder.imgView = (ImageView) v.findViewById(R.id.grid_image);
holder.textView = (TextView) v.findViewById((R.id.numUdm));
v.setTag(holder);
} else {
holder = (ViewHolder) v.getTag();
}
System.out.println(("Position:" + position));
bancale banc = bancali.get(position);
if (banc.statoInventario == 0) {
holder.imgView.setImageResource(R.drawable.unchecked);
}
else {
holder.imgView.setImageResource(R.drawable.checked);
}
holder.textView.setText(banc.numeroudm);
System.out.println(banc.numeroudm);
if (position % 2 == 0) {
v.setBackgroundColor(Color.LTGRAY);
} else {
v.setBackgroundColor(Color.WHITE);
}
return v;
}
public static class ViewHolder {
private TextView textView;
private ImageView imgView;
}
}
and that's my xml

I don't understand why the gridadapter is not Loading all items in my arraylist but it seems only loading the first and at the end it isn't displayed.
Someone can help me?
Thanks

imageview.setImageResource(id) where id is in your int array. See the documentation for ImageView for details. It is the same as you have in your code just in the onClick() handler.
setImageResource
void setImageResource (int resId)
Sets a drawable as the content of this ImageView.
This does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup. If that's a concern, consider using setImageDrawable(android.graphics.drawable.Drawable) or setImageBitmap(android.graphics.Bitmap) and BitmapFactory instead.

Hi everyone thanks for the help. I solved it by using view page adapter. Every onclick button I will change the adapter. Thank you!!

how to get image view from grid layout to alert dialog

I have an array of images, and wanted to display image from it, to alert dialog when we click on grid item.
Here is my class:

I have an array of images, and wanted to display image from it, to alert dialog when we click on grid item.

Do something like this:
grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(MainActivity.this, "You Clicked at " +web[+ position], Toast.LENGTH_SHORT).show();
mydialog dialog = new mydialog();
int imageResource = imageId[position];
dialog.setImageResource(imageResource);
dialog.show(getSupportFragmentManager(),"my_dialog");
}
});
And in your mydialog class declare int variable
private int imageResource;
And create a method:
public void setImageResource(int imageResource) {
this.imageResource = imageResource;
}
now you can set image resource to imageview in onCreateView method of mydialog class

Inside your myDialog class,just have a setter method which stores the Drawable Resource id , like shown below
public void setImageIdToDisplay(int aDrawableId) {
mDrawableId = aDrawableId;
}
and in your oncreateview method of myDialog class, just set the image resource id to the imageview
iv.setImageResource(mDrawableId);
and in your MainActivity's onItemClick listner of gridview, pass the drawable resource id as shown below
grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(MainActivity.this, "You Clicked at " +web[+ position], Toast.LENGTH_SHORT).show();
mydialog dialog = new mydialog();
dialog.setImageIdToDisplay(imageId[position]);
dialog.show(getSupportFragmentManager(),"my_dialog");
}
});

View Pager(Handling Event Listener)

I created a Image Slider using View Pager.
I Tried using setOnPageChangeListener but It only triggered when
the user change the page of the viewpager.
What I'm doing(still no luck) is when the user tap on the screen
Another layout will appear.
But Im stuck to triggering the TAP event.
Here's my codes.
import android.content.Context;
import android.os.Bundle;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.Toast;
import com.thesis.juandirection.juandirectionfinale.R;
import uk.co.senab.photoview.PhotoViewAttacher;
public class viewInfo extends AppCompatActivity {
private ViewPager viewPager;
private CustomSwipeAdapter adapter;
PhotoViewAttacher mAttacher;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_info);
viewPager = (ViewPager) findViewById(R.id.view_pager);
adapter = new CustomSwipeAdapter(this);
viewPager.setAdapter(adapter);
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
Toast.makeText(getBaseContext(), "" + position, Toast.LENGTH_LONG).show();
}
});
}
public class CustomSwipeAdapter extends PagerAdapter {
private int[] image_resources = {R.drawable.bsu, R.drawable.gameover2};
private Context context;
private LayoutInflater layoutInflater;
public CustomSwipeAdapter(Context context) {
this.context = context;
}
#Override
public int getCount() {
return image_resources.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return (view == (LinearLayout) object);
}
#Override
public Object instantiateItem(View container, int position) {
layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View item_view = layoutInflater.inflate(R.layout.swipe_layout, (ViewGroup) container, false);
ImageView imageView = (ImageView) item_view.findViewById(R.id.image_view);
imageView.setPadding(5, 5, 5, 5);
imageView.setImageResource(image_resources[position]);
((ViewGroup) container).addView(item_view);
mAttacher = new PhotoViewAttacher(imageView);
mAttacher.update();
return item_view;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((LinearLayout) object);
}
}
}
And the activit's XML.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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/pls"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:orientation="vertical"
tools:context="com.thesis.juandirection.juandirectionfinale.viewInfos.viewInfo">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"></android.support.v4.view.ViewPager>
</LinearLayout>
And this is the XML layout that will be infalted.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
android:background="#000"
>
<ImageView
android:id="#+id/image_view"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:gravity="center"
/>
</LinearLayout>
What I doing is when the user Tap on the Image.
Infos of the image will show on the Same Screen.(Like Facebook viewing photo)

Unable to get custom spinner in android

I have followed this link to learn about implementing custom spinner. My requirement is just to get drop down menu on clicking a image, it should be like a drop down menu where in i load contents to the list from backend.
