You know how to show images in gridView. after this perform action of
grid.setOnItemClickListener(new OnItemClickListener(){
Intent intent = new Intent
(getApplicationContext(), ViewImage.class);
intent.putExtra("filename", fileName);
//here fileName is something which tells the next activity about "selected image"
//It can be ImageLocation/ImageName/ImageID/ImageURL
startActivity(intent);
}
ViewImage.class
//here I assume that you send the ImageFile in the extra.
//so, converted it into bitmap and showed in the ImageView
Bundle extras = getIntent().getExtras();
BitmapFactory.Options bfo = new BitmapFactory.Options();
bfo.inSampleSize = 2;
filename = extras.getString("filename");
mBitmap = BitmapFactory.decodeFile(filename, bfo);
imageview.setbitmap(mbitmap);

You should do something like this in your setOnItemClickListener, I m using your code and improving it
mGridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position,long id) {
// use gridItem position to get the Image from mThumbsIds
int image = mThumsIds[position] // here I m passing the position of GridViewItem
Intent intent =new Intent(getApplicationContext(),MyImageViewActivity.class);
intent.putExtra("image", image);
startActivity(intent);
}
});
You do not need to pass Bundle if you are just sending a single Image ID
now in your ViewImage.class you can get the image from the intent using
I m using Glide to show you how to display this Image in ImageView
int image = getIntent().getIntExtra("image");
//now you can use this "image" variable to display image
ImageView imageView = findViewById(R.id.imageView);
Glide.with(this).load(image).into(imageView); // here pass you imageView in the last method as parameter
Hope this will help!

On itemClick, just pass the position
mGridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position,long id) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Image"+(position+1), Toast.LENGTH_SHORT).show();
Intent myIntent = new Intent(MyGridView.this, MyImageViewActivity.class);
myIntent.putInt("image", position);
startActivityForResult(myIntent, 0);
}
});
In other Activity,
public class MyImageViewActivity extends AppCompatActivity {
Integer[] mThumbsIds = {
R.drawable.image1,R.drawable.image2,
R.drawable.image3,R.drawable.image4,
R.drawable.image5,R.drawable.icon,
R.drawable.icon,R.drawable.icon,
R.drawable.icon
};
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_question7_spinner_background);
Intent intent = getIntent();
int position = intent.getIntExtra("image", 0);
int imageId = mThumbsIds[position];
}
}

Changing the default listViews item clicked to StringBuffer instead (displays popup by default)

I have a ListView that displays a list of items and I want to display further more details when any item is clicked using StringBuffer. But I'm having an issue because android default setOnItemClickListener bypasses the StringBuffer view that I'm defining inside the click event, and just displays the the item view in a popup.
Here is my code and I will include some screen shots in order to clarify my point a bit more

Here is what I get
here is the logcat error after making the modifications
You have defined onClickListener on your list-items (rowView.setOnClickListener) - this is what gets called instead of the listView's setOnItemClickListener. You need to remove (comment out) this in the CustomListAdapter class:
rowView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
}
});
You need to also call listView.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS); so that only the listView's item click listener can be invoked even if the row item of list are set as focusable or clickable.
Then the dialog should show as you'd expect. Please try this and let us know if it works or what errors you get.

Saving image to SD card not working

Having a problem at the bottom, I'm trying to create a case to save the image to SD card yet it isn't working and I don't know why.
I think it's got something to do with the getRawResource but still not sure.
Thanks for any help!!!

Did you verify you have write permission to sdcard ? (this is WRITE_EXTERNAL_STORAGE)
Also, you should make sure you look at the right mount point to find the image (can be "internal sdcard" for some devices, for example).

how to view next image in imageview?

Hi I have images in grid view. when i click my grid view images, it's display in full screen. if i want view another image go back in grid view then select another image view in full screen. i feel it's hard one.. so i am trying to view images full screen view using to swipe....no idea how to create this method please guide me and give some nice codes also...
This is my working app screen shot:

Implement OnGestureListener in ViewImage activity and capture swipe from user.
For displaying previous or next image, use cursor.
Store all image filenames in array when you are populating into Gridview and then pass that array to another view from that array you can get all images instead of go back to gridview for selecting images..
The easiest way to do this is indeed like RajaReddy P said: create an array with the filenames/urls pass it to the ViewImage activity...
For the ViewImage activity I really would use the ViewPager! Really easy to implement and the swiping is handled for you!
