How to pick up multiple image from gallery in androd studio

Hello friends today we will learn about that How to pick up multiple image from gallery in androd studio.

Many times we make such apps in which we have to show the image after dragging it from gallery or camera.So we have some problem in solving it, so today we will solve this problem very easily.

We will solve this problem step by step

Step 1.Create program

First of all, to create a project, first of all, after opening Android Studio, we will create a project.After creating the project we will see two files activity_main.xml and MainActivity.java

Step 2.

After the project is created, we will see the activity_main .xml, in which the image we will pick up will show the image in it.So first we will paste the below code in activity_main.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

  <Button
      android:id="@+id/pickUp"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Pick"
      android:background="@color/purple_200"
      android:layout_gravity="center"
      android:layout_marginTop="5dp"/>

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="5dp"
        android:textSize="18sp"
        android:textStyle="bold"
        android:textColor="@color/black"/>

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        android:layout_marginTop="5dp"/>

</LinearLayout>

In activity_main we have a button a TextView and in the last we have used recyclerview to show an image according to the list.After this we will perform the operation on the button textView RecyclerView in MainActivity.java

MainActivity.java

package com.example.multiplefiles;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import androidx.recyclerview.widget.GridLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

import android.Manifest;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
  RecyclerView recyclerView;
  TextView textView;
  Button pick;
  ArrayList<Uri>uri=new ArrayList<>();
  PictureAdapter recyclerAdapter;
  private static final int Read_permission=101;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        recyclerView=findViewById(R.id.recyclerView);
        textView=findViewById(R.id.text);
        pick=findViewById(R.id.pickUp);
        recyclerAdapter=new PictureAdapter(uri);
        recyclerView.setLayoutManager(new GridLayoutManager(MainActivity.this,4));
        recyclerView.setAdapter(recyclerAdapter);
        if(ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED){
            ActivityCompat.requestPermissions(MainActivity.this,new String [] {Manifest.permission.READ_EXTERNAL_STORAGE},Read_permission );
        }

        pick.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent =new Intent();
                intent.setType("image/*");
                if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN_MR2)
                {
                    intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE,true);
                }
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,"Select Picture"),1);
            }
        });

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode==1 && resultCode== Activity.RESULT_OK)
        {
            if (data.getClipData()!=null)
            {
                int x=data.getClipData().getItemCount();
                for (int i=0;i<x;i++)
                {
                    uri.add(data.getClipData().getItemAt(i).getUri());
                }

                recyclerAdapter.notifyDataSetChanged();
                textView.setText("Photos("+uri.size()+")");
            }
            else if (data.getData()!=null)
            {
                String imageUrl=data.getData().getPath();
                uri.add(Uri.parse(imageUrl));
            }
        }
    }
}

After pasting this code we will see many error To fix this error, after pressing alt+enter, the error will be fixed but here we will see an error named PictureAdapter.To fix this, we will create a class named PictureAdapter.whose code is given below

PictureAdapter.java

package com.example.multiplefiles;

import android.net.Uri;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import java.util.ArrayList;

public class PictureAdapter extends RecyclerView.Adapter<PictureAdapter.ViewHolder> {
    private ArrayList<Uri> array;

    public PictureAdapter(ArrayList<Uri> array) {
        this.array = array;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflter=LayoutInflater.from(parent.getContext());
        View view=inflter.inflate(R.layout.item,parent,false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
      holder.imageView.setImageURI(array.get(position));
    }

    @Override
    public int getItemCount() {
        return array.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        ImageView imageView;
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            imageView=itemView.findViewById(R.id.imageView);
        }
    }
}

        android:scaleType="centerCrop"
        app:layout_constraintDimensionRatio="1"
        tools:ignore="MissingConstraints" />
