android custom listview with gallery images

android custom listview with gallery images - android

I'm trying to add all the images contained in a folder in my custom listview, where I show a thumbnail of the photo and a little description.
I've found a lot of examples showing images from URL or drawable folder in Android Studio, but nothing working for me that loads a picture located in /storage/emulated/0/DCIM/Camera/AAAAMMGG_HHMMSS.jpg
Here is my code - MainActivity:
import android.content.ContentValues;
public class MainActivity extends ActionBarActivity implements OnClickListener {
public int PHOTO_REQUEST_CODE = 1;
private Uri fileUri;
private ArrayAdapter<String> adapter;
TextView ceScanResults;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Set a toolbar to replace the action bar.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
View addButton = findViewById(mci);
ArrayList<ListItem> listData = getListData();
final ListView listView = (ListView) findViewById(R.id.custom_list);
listView.setAdapter(new CustomListAdapter(this, listData));
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
ListItem newsData = (ListItem) listView.getItemAtPosition(position);
Toast.makeText(MainActivity.this, "Selected :" + " " + newsData, Toast.LENGTH_LONG).show();
}
});
initViews();
}
private ArrayList<ListItem> getListData() {
ArrayList<ListItem> listMockData = new ArrayList<ListItem>();
String[] images = getResources().getStringArray(R.array.images_array);
String[] headlines = getResources().getStringArray(R.array.headline_array);
for (int i = 0; i < images.length; i++) {
ListItem newsData = new ListItem();
newsData.setUrl(images[i]);
newsData.setHeadline(headlines[i]);
newsData.setReporterName("CE code");
newsData.setDate("28/07/2015 - 10:31");
listMockData.add(newsData);
}
return listMockData;
}

} else {

}
ListItem newsItem = listData.get(position);
holder.headlineView.setText(newsItem.getHeadline());

}
return convertView;
}
static class ViewHolder {

}
}
My class ImageDownloaderTask:

}
}

I'm using this library to load images from an URL
https://github.com/thest1/LazyList

try using code like this in Your adapter:
File img = new File("/sdcard/image.jpg");
if(img.exists()){
Bitmap bitmap = BitmapFactory.decodeFile(img.getAbsolutePath());
holder.imageView.setImageBitmap(bitmap);
}

how can i crop the image and store it in gridview?

i am building a app in which user can capture image from camera and then edit that image and store / display the image in a gridview.the problem i am facing is that when the user capture the image instead of crop the image it directly display it in gridview . i need help in this thanks in advance
this is my code

Let me know if it works
first of all change
startActivityForResult(CropIntent, 1);
to
`startActivityForResult(CropIntent, 2);`
and add to onActivityResult add this:
picUri = Uri.parse(_path);
after that in your onActivityResult remove
listOfImagesPath = null;
listOfImagesPath = RetriveCapturedImagePath();
if(listOfImagesPath!=null){
grid.setAdapter(new ImageListAdapter(this,listOfImagesPath));
}
and add new result like
if(requestCode == CAMERA_CAPTURE){
....
} else if(requestCode == 2){
..
}
and last step in your new statement add this line:
else if(requestCode == 2){
listOfImagesPath = null;
listOfImagesPath = RetriveCapturedImagePath();
if(listOfImagesPath!=null){
grid.setAdapter(new ImageListAdapter(this,listOfImagesPath));
}
}

Use this library. It's very easy to use

Fragment Upload Image to ImageButton

I have tried many different approaches but none of them seem to help, so the problem is the following:

recyclerview footer click to load images

I'm trying to achieve some thing like the image below. Here when recyclerview is empty it will show the camera imageview in footer and when I click on the image, I can select image from camera or gallery (which will be saved in an internal storage folder) and display them in recyclerview. But I'm getting ArrayIndexOutOfBoundsException in onBindViewHolder in case 1. How to display images from internal folder?

OnClick goto new Activity in GridView Android

I take a photo from the camera and store them in a GridView, now when i view them there is no OnClick function to Enlarge or Goto new Activity to Enlarge the selected image, Here's the code:
Where to implement the OnClick method to take the selected image to a new Activity and enlarge it
package com.example.veeresh.myphotogallery;

Use setOnItemClickListener of girdview.
grid = (GridView) findViewById(R.id.gridviewimg);
grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
Toast.makeText(this, "you clicked at : " + position, Toast.LENGTH_LONG).show();
// put your intent here to open activity
}
});

put this code inside your onCreate(...) method.
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// do your stuff.
}
});

When I use this code and click on upload button
I got the following error:
Could not find class 'org.apache.commons.net.ftp.FTPClient', referenced from method com.androidmyway.demo.imagedemo.ImageGallery$ImageGalleryTask.doInBackground

Try using this simple example to upload any file over webserver from here.

You have to add a dependency for using FTPClient class. You can find it easily on anywhere. it is "commons apache" named dependency.
