Combination of Grid and Gallery Views ( While select one image in GridView that image open in Gallery )

 Demo:

1)Main Activity:

 

package com.venky.gridandgallery;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.GridView;

import android.widget.ImageView;

public class GridandGalleryActivity extends Activity {

      /** Called when the activity is first created. */

      GridView gridView;

      @Override

      public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.main);

            gridView = (GridView) findViewById(R.id.gridView1);

            ImageAdapter ia = new ImageAdapter();

            gridView.setAdapter(ia);

      }

      class ImageAdapter extends BaseAdapter {

            public int getCount() {

                  // TODO Auto-generated method stub

                  return images.length;

            }

            public Object getItem(int position) {

                  // TODO Auto-generated method stub

                  return null;

            }

            public long getItemId(int position) {

                  // TODO Auto-generated method stub

                  return 0;

            }

            public View getView(final int position, View convertView,

                        ViewGroup parent) {

                  // TODO Auto-generated method stub

                  ImageView image = new ImageView(getApplicationContext());

                  image.setLayoutParams(new GridView.LayoutParams(100, 100));

                  image.setImageResource(images[position]);

                  image.setOnClickListener(new OnClickListener() {

                        @Override

                        public void onClick(View v) {

                              // TODO Auto-generated method stub

                              Intent intent = new Intent(getApplicationContext(),

                                          GalleryView.class);

                              intent.putExtra("position", position);

                              startActivity(intent);

                        }

                  });

                  return image;

            }

      }

      int[] images = { R.drawable.a1, R.drawable.a2, R.drawable.a3,

                  R.drawable.a4, R.drawable.a5, R.drawable.a6, R.drawable.a7,

                  R.drawable.a8, R.drawable.a9, R.drawable.a10, R.drawable.a11,

                  R.drawable.a12 };

}

2)Gallery Activity:

 

package com.venky.gridandgallery;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.Gallery;

import android.widget.Gallery.LayoutParams;

import android.widget.ImageView;

public class GalleryView extends Activity {

      Gallery gallery;

      @Override

      public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.gallery);

            Intent intent = getIntent();

            int pos = intent.getIntExtra("position", 0);

            gallery = (Gallery) findViewById(R.id.gallery1);

            ImageAdapter ia = new ImageAdapter();

            gallery.setAdapter(ia);

            gallery.setSelection(pos);

      }

      class ImageAdapter extends BaseAdapter {

            public int getCount() {

                  // TODO Auto-generated method stub

                  return images.length;

            }

            public Object getItem(int position) {

                  // TODO Auto-generated method stub

                  return null;

            }

            public long getItemId(int position) {

                  // TODO Auto-generated method stub

                  return 0;

            }

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

                  // TODO Auto-generated method stub

                  ImageView imageView = new ImageView(getApplicationContext());

                  imageView.setLayoutParams(new Gallery.LayoutParams(

                              LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

                  imageView.setImageResource(images[position]);

                  return imageView;

            }

      }

      int[] images = { R.drawable.a1, R.drawable.a2, R.drawable.a3,

                  R.drawable.a4, R.drawable.a5, R.drawable.a6, R.drawable.a7,

                  R.drawable.a8, R.drawable.a9, R.drawable.a10, R.drawable.a11,

                  R.drawable.a12 };

}

3)main.xml:

 

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="#FFFFFF"

    android:orientation="vertical" >

    <GridView

        android:id="@+id/gridView1"

        android:layout_width="match_parent"

        android:layout_height="fill_parent"

        android:numColumns="3" >

    </GridView>

</LinearLayout>

4)gallery.xml:

<?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" >

    <Gallery
