从图库中选择的图像未在Imageview中设置

Question

Im trying to upload image from gallery.

Here is the code I'm using.

image view in the xml file -

<ImageView
   android:id="@+id/imgView"
   android:layout_width="20dp"
   android:layout_height="20dp"
   android:layout_marginLeft="260dp"
   android:layout_weight="1"/>

code in the java file -

public class AddLabReport02 extends ActionBarActivity {

private static int RESULT_LOAD_IMAGE = 1;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_lab_report02);


        uploadLabReport = (Button) findViewById(R.id.uploadLabReport);

        uploadLabReport.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, RESULT_LOAD_IMAGE);
            }
        });

    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            ImageView imageView = (ImageView) findViewById(R.id.imgView);
            imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

        }


    }

}

Here, when I click on uploadLabReport button, I can goto Gallery and select the image. But, after that Image is not set in the imageView.

I don't see any wrong in my code. Can someone look at it?

Thanks in advance :)

Answer 1

Call below method in your Button click event.

uploadLabReport.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View arg0) {
       pickImage();
    }
});

Here is code i have used. use it according to your need

private static final int GALLERY_PHOTO = 111;
private void pickImage(){
     Intent chooserIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
     chooserIntent.setType("image/*");
     startActivityForResult(chooserIntent, GALLERY_PHOTO);
}

in your onActivityResult() you should use like this.

 if (resultCode == GALLERY_PHOTO && data.getData() != null) {
        String filePath = GetFilePathFromDevice.getPath(AddLabReport02.this, data.getData());
       ImageView imageView = (ImageView) findViewById(R.id.imgView);
       imageView.setImageBitmap(BitmapFactory.decodeFile(filePath));
  }

Here is class used for getting file path from URI .

public final class GetFilePathFromDevice {

    /**
     * Get file path from URI
     *
     * @param context context of Activity
     * @param uri     uri of file
     * @return path of given URI
     */
    public static String getPath(final Context context, final Uri uri) {
        final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
        // DocumentProvider
        if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
            // ExternalStorageProvider
            if (isExternalStorageDocument(uri)) {
                final String docId = DocumentsContract.getDocumentId(uri);
                final String[] split = docId.split(":");
                final String type = split[0];
                if ("primary".equalsIgnoreCase(type)) {
                    return Environment.getExternalStorageDirectory() + "/" + split[1];
                }
            }
            // DownloadsProvider
            else if (isDownloadsDocument(uri)) {
                final String id = DocumentsContract.getDocumentId(uri);
                final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
                return getDataColumn(context, contentUri, null, null);
            }
            // MediaProvider
            else if (isMediaDocument(uri)) {
                final String docId = DocumentsContract.getDocumentId(uri);
                final String[] split = docId.split(":");
                final String type = split[0];
                Uri contentUri = null;
                if ("image".equals(type)) {

                } else if ("video".equals(type)) {
                    contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
                } else if ("audio".equals(type)) {
                    contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
                }
                final String selection = "_id=?";

            return uri.getPath();

Answer 2

This code works fine. Figured out it myself. :)

public class AddPrescription02 extends ActionBarActivity implements View.OnClickListener {

    private ImageView imageView;

    private Spinner illnessType;

    private Button uploadPrescription;

    private static int RESULT_LOAD_IMAGE = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_prescription02);

        illnessType = (Spinner) findViewById(R.id.selectIllnessType);
        uploadPrescription = (Button) findViewById(R.id.uploadPrescription);

        imageView = (ImageView) findViewById(R.id.imgView);

        addItemsOnSpinnerIllnessType();

        uploadPrescription.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        Intent galleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(galleryIntent, RESULT_LOAD_IMAGE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && data!=null)
        {
            Uri selectedImage = data.getData();
            imageView.setImageURI(selectedImage);
        }
    }
}

Answer 3

1- fire Intent As:

startActivityForResult(new Intent(Intent.ACTION_PICK,
                                       MediaStore.Images.Media.INTERNAL_CONTENT_URI),
                               GALLERY_PIC_REQUEST);

2- in onActivityResulr write this code:

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == GALLERY_PIC_REQUEST) {

                Uri selectedImage = data.getData();
                if (selectedImage != null) {
                    Cursor cursor = mContext.getContentResolver().query(selectedImage, new String[]
                                    {MediaStore.Images.ImageColumns.DATA},
                            null, null, null);
                    cursor.moveToFirst();
                    String path = cursor.getString(0);
                    Log.e("","$$$$$$$$$$ path of gallery " + path);
                    cursor.close();
                    setImageUser(path,true);
                }

            } 
}
}

Hope This will help you.

Answer 4

Use this way it will help

private void uploadImage(){
    class UploadImage extends AsyncTask<Bitmap,Void,String>{

        ProgressDialog loading;
        RequestHandler rh = new RequestHandler();

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            loading = ProgressDialog.show(MainActivity.this, "Uploading Image", "Please wait...",true,true);
        }

        @Override
        protected void onPostExecute(String s) {
            super.onPostExecute(s);
            loading.dismiss();
            Toast.makeText(getApplicationContext(),s,Toast.LENGTH_LONG).show();
        }

        @Override
        protected String doInBackground(Bitmap... params) {
            Bitmap bitmap = params[0];
            String uploadImage = getStringImage(bitmap);

            HashMap<String,String> data = new HashMap<>();
            data.put(UPLOAD_KEY, uploadImage);

            String result = rh.sendPostRequest(UPLOAD_URL,data);

            return result;
        }
    }

Answer 5

I used below code to show image on ImageView

Intent intent = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, CHOOSE_FROM_GALLERY);

Inside onActivityResult:

  if (requestCode == CHOOSE_FROM_GALLERY){

                 Uri selectedImage = data.getData();
