Android Studio Image to Upload Not Changing
I want to upload epitome from gallery in my android app. When I click on button, the gallery should exist opened. After selecting image, I desire to open another action named UploadActivity. There the thumbnail of the paradigm should exist previewed. The Upload Button will below the thumbnail.
Simply when I Cull photo from gallery, then the thumbnail of the prototype are not previewing. I am unable to upload the photo also. My Code goes hither: (Scan.Coffee)
private static final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100; public static final int MEDIA_TYPE_IMAGE = 1; private static final int SELECT_IMAGE = 2; private Uri fileUri; // file url to store epitome/video ImageView dummy; individual Push button btnCapturePicture; private Button btnGallery; @Override protected void onCreate(Package savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.scan); dummy = (ImageView) findViewById(R.id.dummyphoto); btnCapturePicture = (Button) findViewById(R.id.btnCapturePicture); btnGallery = (Button) findViewById(R.id.btnGallery); /** * Capture epitome button click outcome */ btnCapturePicture.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // capture picture show captureImage(); } }); btnGallery.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View v){ openGallery(); } }); // Checking photographic camera availability if (!isDeviceSupportCamera()) { Toast.makeText(getApplicationContext(), "Sorry! Your device doesn't support camera", Toast.LENGTH_LONG).show(); // volition close the app if the device does't have camera finish(); } } /** * Checking device has camera hardware or not * */ private boolean isDeviceSupportCamera() { if (getApplicationContext().getPackageManager().hasSystemFeature( PackageManager.FEATURE_CAMERA)) { // this device has a camera render true; } else { // no camera on this device return false; } } /** * Launching photographic camera app to capture image */ individual void captureImage() { Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // start the image capture Intent startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE); } /** * Launching Gallery to Choose Image */ private void openGallery(){ Intent intent = new Intent(); intent.setType("paradigm/*"); intent.setAction(Intent.ACTION_GET_CONTENT); fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); startActivityForResult(Intent.createChooser(intent, "Select Image"),SELECT_IMAGE); } /** * Here we store the file url as information technology will be zero after returning from camera * app */ @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); // relieve file url in packet as information technology will be cypher on screen orientation // changes outState.putParcelable("file_uri", fileUri); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); // become the file url fileUri = savedInstanceState.getParcelable("file_uri"); } /** * Receiving activity event method volition be called after closing the camera * */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // if the result is capturing Image if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) { if (resultCode == RESULT_OK) { // successfully captured the paradigm // launching upload action launchUploadActivity(true); } else if (resultCode == RESULT_CANCELED) { // user cancelled Image capture Toast.makeText(getApplicationContext(), "User cancelled image capture", Toast.LENGTH_SHORT) .show(); } else { // failed to capture paradigm Toast.makeText(getApplicationContext(), "Sorry! Failed to capture image", Toast.LENGTH_SHORT) .show(); } } else if (requestCode == SELECT_IMAGE) { if (resultCode == Activeness.RESULT_OK) { if (data != cypher) { launchUploadActivity(true); } } else if (resultCode == Activity.RESULT_CANCELED) { Toast.makeText(getApplicationContext(), "Cancelled", Toast.LENGTH_SHORT).show(); } } } private void launchUploadActivity(boolean isImage){ Intent i = new Intent(Browse.this, UploadActivity.course); i.putExtra("filePath", fileUri.getPath()); i.putExtra("isImage", isImage); startActivity(i); } UploadActivity.Java Lawmaking goes hither:
