package com.example.gallerytest;

import java.io.File;

import android.net.Uri;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.ImageView;

import android.widget.TextView;

public class GalleryAdapter  extends BaseAdapter

{

          MainActivity mainActivity;

          String path="/storage/sdcard0/DCIM/Camera/";

          File f=new File(path);

          

          

          String[] file=f.list();

          LayoutInflater inflate;

          

public GalleryAdapter(MainActivity mainActivity)

{

this.mainActivity=mainActivity;

         inflate=LayoutInflater.from(mainActivity);

 

}

@Override

public int getCount() {

return file.length;

  }

@Override

public Object getItem(int arg0) {

// TODO Auto-generated method stub

return arg0;

}

@Override

public long getItemId(int arg0) {

// TODO Auto-generated method stub

return 0;

}

@Override

public View getView(int position, View convertView, ViewGroup arg2) {

convertView=inflate.inflate(R.layout.adpater,null);

TextView tv=(TextView)convertView.findViewById(R.id.textView1);

ImageView img=(ImageView)convertView.findViewById(R.id.imageView1);

tv.setText(file[position]); 

    File f=new File(path+file[position]);

    img.setImageURI(Uri.fromFile(f));  

    

return convertView;

}

}

Step 5> Write below permission in AndroidManifest.xml

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

    

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.gallerytest"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
 
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
 
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="com.example.gallerytest.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
