Gridview of image from sdcard directory

I want show image in gridview from sdcard directory.i use this code.But when i load image by type : bitmap.getView in gridview adapter need Integer[] array.how i can fix it?
public class LoadPic extends Activity {
Integer[] imageIDs = {
R.drawable.user,
R.drawable.user,
R.drawable.user,
R.drawable.user,
R.drawable.user,
R.drawable.user,
R.drawable.user
};
int numberOfImages=0;
Bitmap[] m;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.load_pic);
Intent gett = getIntent();
String _area = gett.getStringExtra("area");
String _domain = gett.getStringExtra("domain");
String _block = gett.getStringExtra("block");
String _melk = gett.getStringExtra("melk");
String _build = gett.getStringExtra("build");
String _apar = gett.getStringExtra("apar");
String _senfi = gett.getStringExtra("senfi");
File dir = new File(Environment.getExternalStorageDirectory()
+ "/momayezi/"+_area+"-"+_domain+"-"+_block+"-"+_melk+"-"+_build+"-"+_apar+"-"+_senfi);
File[] files = dir.listFiles();
numberOfImages=files.length;
for (int i=1;i<=numberOfImages;i++)
{
File img = new File("/sdcard/momayezi/"+_area+"-"+_domain+"-"+_block+"-"+_melk+"-"+_build+"-"+_apar+"-"+_senfi+"/pic"+i+".png");
if(img.exists())
{
Bitmap bit = BitmapFactory.decodeFile(img.getAbsolutePath());
}
}
GridView gridView = (GridView) findViewById(R.id.gridview);
gridView.setAdapter(new ImageAdapter(this));
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent,
View v, int position, long id) {
Toast.makeText(getBaseContext(),
"pic" + (position + 1) + " selected",
Toast.LENGTH_SHORT).show();
}
});
}
public class ImageAdapter extends BaseAdapter
{
private Context context;
public ImageAdapter(Context c)
{
context = c;
}
//---returns the number of images---
public int getCount() {
return numberOfImages;
}
//---returns the ID of an item---
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
//---returns an ImageView view---
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(context);
imageView.setLayoutParams(new GridView.LayoutParams(185, 185));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(7, 7, 7, 7);
} else {
imageView = (ImageView) convertView;
}
/**/
imageView.setImageResource(imageIDs[position]);
/**/
return imageView;
}
}
}
please help how i can use image in this class(adapter).

If you want to show images from sdcard into your grid view use any imageloader library
Universal Image Loader
https://github.com/nostra13/Android-Universal-Image-Loader
then you need to create a string array or a model class instead of that integer array.
Please refer the below tutorials.
http://wptrafficanalyzer.in/blog/loading-thumbnail-images-in-a-gridview-and-opening-original-images-in-alertdialog-using-media-content-providers/

replace
public int getCount() {
return numberOfImages;
}
with
public int getCount() {
return imageIDs.length();
}

First properly explain what do want to set Drawable or Bitmap?
If Bitmap then this is how you should set bitmap(make a list of bitmaps and then):
imageView.setImageBitmap(bitmaps[position]);
if Drawable then(make list of drawable id's)
imageview.setImageResource(drawables[position]);
This is how make bitmap list:
ArrayList<Bitmap> bitmaps = new ArrayList<Bitmap>();
File dir = new File(Environment.getExternalStorageDirectory()
+ "/momayezi/"+_area+"-"+_domain+"-"+_block+"-"+_melk+"-"+_build+"-"+_apar+"-"+_senfi);
File[] files = dir.listFiles();
numberOfImages=files.length;
for (int i=1;i<=numberOfImages;i++)
{
File f = new File("/sdcard/momayezi/"+_area+"-"+_domain+"-"+_block+"-"+_melk+"-"+_build+"-"+_apar+"-"+_senfi+"/pic"+i+".png");
Bitmap bmp = BitmapFactory.decodeFile(f.getAbsolutePath());
if(bmp!=null){
bitmaps.add(bmp);
}
}

getting image id from ImageAdapter

I'am new to android and I've a project of making a grid view of images and onclick on image it shows it , thats the ImageAdapter class code
public class ImageAdapter extends BaseAdapter{
private static LayoutInflater inflater = null;
private Activity activity;
private String mode = "";
int[] images=null ;
public ImageAdapter(Activity act, String mode , int[] images){
inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
activity = act;
this.mode = mode;
this.images= images ;
}
public ImageView getImage(int pos)
{
ImageView im = (ImageView) getItem(pos);
return im ;
}
#Override
public int getCount() {
return images.length;
}
#Override
public Object getItem(int position) {
return new Integer(images[position]);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
if(mode.equalsIgnoreCase("grid")){
if (view == null) {
view = inflater.inflate(R.layout.each_image1, null);
}
ImageView iv = (ImageView)view.findViewById(R.id.imageView);
iv.setImageResource(images[position]);
} else if(mode.equalsIgnoreCase("gallery")){
if (view == null) {
view = inflater.inflate(R.layout.each_image_gallery, null);
}
ImageView iv = (ImageView)view.findViewById(R.id.imageView);
iv.setImageResource(images[position]);
}
return view;
}
}
thats my grid activity
public class GridActivity extends Activity {
GridView grid = null;
public static ImageAdapter adapter1 ;
public static ImageAdapter adapter2 ;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.grid);
adapter1= new ImageAdapter(GridActivity.this, "grid" , Images.images1);
adapter2 = new ImageAdapter(GridActivity.this, "grid" , Images.images2);
Intent i = this.getIntent();
if (i!=null)
{
String unique = i.getExtras().getString("Unique");
if (unique.equals("islam"))
{
Toast.makeText(GridActivity.this, "islam", Toast.LENGTH_LONG).show();
grid = (GridView)findViewById(R.id.gridView1);
grid.setAdapter(adapter1);
}
if (unique.equals("natural"))
{
Toast.makeText(GridActivity.this, "nat", Toast.LENGTH_LONG).show();
grid = (GridView)findViewById(R.id.gridView1);
grid.setAdapter(adapter2);
}
}
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos,long id) {
Intent i = new Intent(GridActivity.this, imgPrevActivity.class);
i.putExtra("selectedIntex", pos);
startActivity(i);
Toast.makeText(GridActivity.this,"ddd",Toast.LENGTH_LONG).show();
}
});
}
}
and this is the activity where it supposes to show any clicked on image
public class imgPrevActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.each_image1);
ImageView im = (ImageView)findViewById(R.id.imageView);
int pos = getIntent().getExtras().getInt("selectedIntex");
// ImageAdapter adapter = new ImageAdapter(imgPrevActivity.this, "image prev", null);
long Id= GridActivity.adapter1.getItemId(pos);
im.setImageResource((int) Id);
}
}
i've tried to get the position of image clicked on from the grid
then getting the Id from the position
and setting the image view to that ID
but it doesnt work !!
thats where the images are put in arrays
public class Images {
public static int[] images1 = {
R.drawable.buds, R.drawable.cherry_34,
R.drawable.clouds_2, R.drawable.coffee_beans_2,
R.drawable.death_valley_sand_dunes
};
public static int[] images2= {
R.drawable.morning_glory_pool,
R.drawable.pink_flowers, R.drawable.sun_flower,
R.drawable.sunrise_3, R.drawable.yellow_rose_3,
};
}

You have to pass your image resource id with intent. The list item id of adapter is useless because you have new Activity on the screen.
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos,long id) {
Intent i = new Intent(GridActivity.this, imgPrevActivity.class);
i.putExtra("selectedIntex", grid.getAdapter().getItem(pos);
startActivity(i);
Toast.makeText(GridActivity.this,"ddd",Toast.LENGTH_LONG).show();
}
});
and change your code in your ImgPreviewActivity:
public class imgPrevActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.each_image1);
ImageView im = (ImageView)findViewById(R.id.imageView);
int pos = getIntent().getIntExtra("selectedIntex", 0);
im.setImageResource(pos);
}
}
I think it should work

Implementing lazy loading for simplecursoradapter

Here I am getting stored picture paths from the database. So that I am showing the images in the gridview with the help of paths. But as it is shown in my code below, I am loading cursoradapter in the asynctask. The problem here is for the first time it is okay that it takes some time until all images are loaded.
But if user adds one more pic to the database, it again takes much time to load all images as I kept the asynctask in onResume() to make the added picture also visible. The same is the case whenever user adds each picture. Can someone suggest me a simple way to get the last added picture visible in the gridview without having to load all the pictures again. Or in the least case can some one help me implementing lazy adapter to the present cursoradapter if that is not possible?
public class ImagesScreen extends Activity {
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.images_screen);
gridView = (GridView)findViewById(R.id.gridView1);
String[] from = new String[] { Reminders.MOM_PATHS };
int[] to = new int[] {};
dbCon = new SQLiteConnectClass(ImagesScreen.this);
imageCursorAdapter = new ImageCursorAdapter(ImagesScreen.this, R.layout.griditem, null, from, to);
gridView.setAdapter(imageCursorAdapter);
}
protected void onResume() {
super.onResume();
new GetImages().execute((Object[]) null);
}
private class GetImages extends AsyncTask<Object, Object, Cursor> {
#Override
protected Cursor doInBackground(Object... params) {
return dbCon.getAllImages();
}
#Override
protected void onPostExecute(Cursor result) {
imageAdapter.changeCursor(result);
}
public void addpictures(View view){
// code for adding picture paths to the database by transferring to another activity.
}
}
CustomAdapter class:
public class ImageCursorAdapter extends SimpleCursorAdapter{
private int layout;
private LayoutInflater mLayoutInflater;
private Context mContext;
public ImageAdapter(Context context, int layout, Cursor c,String[] from, int[] to) {
super(context, layout, c, from, to,0);
this.layout = layout;
mLayoutInflater=LayoutInflater.from(context);
mContext = context;
}
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = mLayoutInflater.inflate(layout, parent, false);
return v;
}
public void bindView(final View v, final Context context, Cursor c) {
final int id = c.getInt(c.getColumnIndex("id"));
final String imagepath = c.getString(c.getColumnIndex("paths"));
ImageView imageview = (ImageView)v.findViewById(R.id.imageView1);
File imgFile = new File(imagepath);
if(imgFile.exists()){
Bitmap imageBitmap = decodeFile(imgFile);
imageview.setImageBitmap(imageBitmap);
}
}
}

use this code

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

android:id="#+id/RelativeLayout1"
android:layout_width="wrap_content"

<ImageView
android:id="#+id/imageView1"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:src="#drawable/ic_launcher" >
</ImageView>
</RelativeLayout>
i am getting file path directly . u just get the name from sqlite and pass the array string

use Android-Universal-Image-Loader
and set
ImageView imageview = (ImageView)v.findViewById(R.id.imageView1);
File imgFile = new File(imagepath);
if(imgFile.exists()){
imageLoader.displayImage(imageUri(ur file path), imageView);
}

Are you trying to load images from assets folder in your project ??? Well, in that case try reading asset files through AssetManager. I think this might help

Try to get all image from sdcard to show in gallery view

I'm trying to get all of the image that stored in sdcard to show in a gallery view by the code below. But when I use ImageFilter nothing shows up, just a blank screen without any error. Any suggestion?
public class Galmix extends Activity {

I would suggest that u make use of MediaStore . Also check for permissions in ur manifest file

Did you check that File images = new File("/sdcard/"); is returning the actual sdcard root folder? Try using File images = Environment.getExternalStorageDirectory(); instead.
Also, add a line Log.d ("Galmix", mFiles[i]); after mFiles[i] = imagelist[i].getAbsolutePath(); so you know if you are getting the file list or not.
Also, try
return (name.toUpperCase().endsWith(".JPG"));

This might be helpful:
Drawable mImage;
// you can use loop over here
mImage = Drawable.createFromPath("pathName");
//create one Imageview & set its resource mImage
