Click on the Gridview photo and show in another Activity

Question

I’m developing an app that contains a gallery and found a tutorial that showed how to fill the GridView with photo taken from camera.

However, I’m having trouble doing something for when the photo is clicked, open a Activity with the photo clicked.

Follows my code:

public class GaleriaSp extends Activity implements OnClickListener{

    Button captureBtn = null;
    final int CAMERA_CAPTURE = 1;
    private Uri picUri;
    private DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private GridView grid;
    private  List<String> listOfImagesPath;

    public static final String GridViewDemo_ImagePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/GridViewDemo/";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_galeria_sp);

        captureBtn = (Button)findViewById(R.id.capture_btn1);
        captureBtn.setOnClickListener(this);
        grid = ( GridView) findViewById(R.id.gridviewimg);

        listOfImagesPath = null;
        listOfImagesPath = RetriveCapturedImagePath();
        if(listOfImagesPath!=null){
            grid.setAdapter(new ImageListAdapter(this,listOfImagesPath));
       }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_galeria_sp, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onClick(View arg1) {
        if (arg1.getId() == R.id.capture_btn1) {

            try {
    //use standard intent to capture an image
                Intent captureIntent = new         Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    //we will handle the returned data in onActivityResult
                startActivityForResult(captureIntent, CAMERA_CAPTURE);
            } catch(ActivityNotFoundException anfe){
//display an error message
                String errorMessage = "Whoops - your device doesn't support capturing images!";
                Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
                toast.show();
            }
        }
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
   //user is returning from capturing an image using the camera
            if(requestCode == CAMERA_CAPTURE){
                Bundle extras = data.getExtras();
                Bitmap thePic = extras.getParcelable("data");
                String imgcurTime = dateFormat.format(new Date());
                File imageDirectory = new File(GridViewDemo_ImagePath);
                imageDirectory.mkdirs();
                String _path = GridViewDemo_ImagePath + imgcurTime+".jpg";
                try {
                    FileOutputStream out = new FileOutputStream(_path);
                    thePic.compress(Bitmap.CompressFormat.JPEG, 90, out);
                    out.close();
                } catch (FileNotFoundException e) {
                    e.getMessage();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                listOfImagesPath = null;
                listOfImagesPath = RetriveCapturedImagePath();
                if(listOfImagesPath!=null){
                    grid.setAdapter(new ImageListAdapter(this,listOfImagesPath));
                }
            }
        }
    }

    private List<String> RetriveCapturedImagePath() {
        List<String> tFileList = new ArrayList<String>();
        File f = new File(GridViewDemo_ImagePath);
        if (f.exists()) {
            File[] files=f.listFiles();
            Arrays.sort(files);

            for(int i=0; i<files.length; i++){
                File file = files[i];
                if(file.isDirectory())
                    continue;
                tFileList.add(file.getPath());
            }
        }
        return tFileList;
    }

    public class ImageListAdapter extends BaseAdapter
    {
        private Context context;
        private List<String> imgPic;
        public ImageListAdapter(Context c, List<String> thePic)
        {
            context = c;
            imgPic = thePic;
        }
        public int getCount() {
            if(imgPic != null)
                return imgPic.size();
            else
                return 0;
        }

        //---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;

                    }
                }
            }
            return imageView;
        }
    }
}

an Obs: in the other Activity I had to declare these variables.

private int position;
private BitmapFactory.Options bfOptions;

Here the logcat:

In your Adapter, place a Listener in the pictureView:

                imageView.setImageBitmap(bm);
                imageView.setId(position);
                imageView.setLayoutParams(new GridView.LayoutParams(150, 150));
                imageView.setOnClickListener(new View.OnClickListener()
                {
                  @Override
                  public void onClick(View v){
                  String imagem = imgPic.get(position).toString();
                  Intent i = new Intent(GaleriaSp.this, OutraActivity.class);//mude aqui de acordo com a sua activity
                  i.putExtra("img", imagem);
                  startActivity(i);
                }

                });

In the other Activity, receive the image using:

String img = getIntent().getStringExtra("img");

And put the image in the imageView:

FileInputStream fs = null;
            Bitmap bm;
            try {
                fs = new FileInputStream(new File(img));

                if(fs!=null) {
                    bm=BitmapFactory.decodeFileDescriptor(fs.getFD(), null, bfOptions);
                    imageView.setImageBitmap(bm);
                    imageView.setId(position);
                    imageView.setLayoutParams(new GridView.LayoutParams(150, 150));
                }
            } catch (IOException e) {
                e.printStackTrace();
            } finally{
                if(fs!=null) {
                    try {
                        fs.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }
