Sory for my english. I want attach image from gallery and show in edit text with SpannableStringBuilder. I have success for get Image Path from Gallery. After picture selected, Picture Show. But, for the second attach image picture not show and first image attach became a text. any one give me solution ? big thanks.
this is my code:
private void IntentPict() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select File"),MY_INTENT_CLICK);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK){
if (requestCode == MY_INTENT_CLICK){
if (null == data) return;
String selectedImagePath;
Uri selectedImageUri = data.getData();
//there is no problem with get path
selectedImagePath = ImageFilePath.getPath(getApplicationContext(), selectedImageUri);
//pathImag is ListArray<String>
pathImg.add(selectedImagePath);
addImageBetweentext(pathImg);
}
}
}
private void addImageBetweentext(ArrayList<String> listPath) {
SpannableStringBuilder ssb = new SpannableStringBuilder();
for(int i=0;i<listPath.size();i++){
String path = listPath.get(i);
Drawable drawable = Drawable.createFromPath(path);
drawable.setBounds(0, 0, 400, 400);
ssb.append(mBodyText+"\n");
ssb.setSpan(new ImageSpan(drawable), ssb.length()-(path.length()+1),
ssb.length()-1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
mBodyText.setText(ssb);
}
Here's something that should work. I am loading resource drawables instead, just because it was quicker for me to validate, but I tried to keep as mich as possible for your original flow and variable names:
Drawable[] drawables = new Drawable[2];
drawables[0] = getResources().getDrawable(R.drawable.img1);
drawables[1] = getResources().getDrawable(R.drawable.img2);
SpannableStringBuilder ssb = new SpannableStringBuilder();
for (int i = 0; i < drawables.length; i++) {
Drawable drawable = drawables[i];
drawable.setBounds(0, 0, 400, 400);
String newStr = drawable.toString() + "\n";
ssb.append(newStr);
ssb.setSpan(
new ImageSpan(drawable),
ssb.length() - newStr.length(),
ssb.length() - "\n".length(),
Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
}
mBodyText.setText(ssb);
Long story short: the start position for the incremental builder needs to be set to the current length of it, minus what you just added.

I used below codes to pop up system share feature.
public void Share(List<String> filepath)
{
NSObject[] activityItems = new NSObject[filepath.Count];
int i = 0;
foreach (var item in filepath)
{
activityItems[i] = NSUrl.CreateFileUrl(item, false, null);
i++;
}
var activityController = new UIActivityViewController(activityItems, null);
if (UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Phone)
{
// Phone
if (UIApplication.SharedApplication.KeyWindow.RootViewController != null)
UIApplication.SharedApplication.KeyWindow.RootViewController.PresentViewController(
activityController, true, null);
}
else
{
// Tablet
var popup = new UIPopoverController(activityController);
if (UIApplication.SharedApplication.KeyWindow.RootViewController != null)
{
UIView view = UIApplication.SharedApplication.KeyWindow.RootViewController.View;
CGRect rect = new CGRect(view.Frame.Width / 2, view.Frame.Height, 50, 50);
popup.PresentFromRect(rect, view, UIPopoverArrowDirection.Any, true);
}
}
}
Test results:
sharing via Mail App, the result is OK.
sharing via AirDrop, the file name length is normal, OK.
sharing via AirDrop, the file name length is long, FAILED.
For some reason, I can not decrease the file name length, so how to solve the problem?
hello please help me in this regard I want to select pic from gallery and crop the pic and save the pic in some folder
Please help me in this regard
enter code here
private void ProfilePic_Click(object sender, EventArgs e)
{

Add the below code to Crop the image.Modify your OnActivityResult code , try like this. Hope this may help you.
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
if ((requestCode == PickImageId) && (resultCode == Result.Ok) && (data != null))
{
Android.Net.Uri uri = data.Data;
//Toast.MakeText(this, path, ToastLength.Long).Show();
Toast.MakeText(this, uri.ToString(), ToastLength.Long).Show();
// It will crop the image accordingly.
cropPicture(uri);
string path = GetPathToImage(data.Data);
Toast.MakeText(this, uri.ToString(), ToastLength.Long).Show();
Toast.MakeText(this, path, ToastLength.Long).Show();
}
else if(requestCode == CROP_PIC)
{
// Get your cropped image here using Bundle and save the bitmap in particular location.
}
}
private void cropPicture(Android.Net.Uri picUri)
{
try
{
// call the standard crop action intent (the user device may not
// support it)
Intent cropIntent = new Intent("com.android.camera.action.CROP");
// indicate image type and Uri
cropIntent.SetDataAndType(picUri, "image/*");
// set crop properties
cropIntent.PutExtra("crop", "true");
// indicate aspect of desired crop
cropIntent.PutExtra("aspectX", 2);
cropIntent.PutExtra("aspectY", 1);
// indicate output X and Y
cropIntent.PutExtra("outputX", 256);
cropIntent.PutExtra("outputY", 256);
// retrieve data on return
cropIntent.PutExtra("return-data", true);
// start the activity - we handle returning in onActivityResult
StartActivityForResult(cropIntent, CROP_PIC);
}
// respond to users whose devices do not support the crop action
catch (ActivityNotFoundException anfe)
{
Toast toast = Toast
.MakeText(this, "This device doesn't support the crop action!", ToastLength.Long);
toast.Show();
}
}
I need one help.
I am using Appium and I have a scenerio wherein I need to capture an image from the app under test, preserve that image as a baseline image and then capture another image from that app under test and then perform an image comparison between these two images.
Can anyone guide me how to do this please.
This is how you do it:

I am developing a POS application in windows 8.1 (Universal App).
Order receipt will be printed from the application and even I am able to do so.
Printer - EPSON TM-U220D
Input - A grid is being created pragmatically with dynamic content within the ViewModel. So this grid is the input for printer
Output - In the print preview (Attahced pic 1) all looks good but when the receipt is actually printed then content is cut off from the end (Attahced pic 2)
PIC 1
PIC 2
Observations -
If I print a normal text file manually using print command (Right click file and then print), then all content is printed perfectly.
If I print that SAME content, from the application, by creating Dynamic grid, then with Small font size print is good but with bit bigger font size content again cuts off.
Tried -
Optimized the code for Creating Gird, by specifying height
Questions-
If preview is all good then why not output
Did anyone tried using ePOS-Print_SDK_141020E for Windows Store app?

Note: This Error displaying first "javax.microedition.media.MediaException: There is already another active Player. Call Player.close() on the existing Player to free up the resources." and camera gets open and when i try to take picture this error displays "Error Class Java.lang.ArrayIndexOutOfBoundsException: Index 0>=0"
After _videoControl.getSnapshot( encoding ) has been called you need to close player (i.e. to call player.close(). And that's exactly what the exception tells about.
However this method of taking images is highly unreliable - you'll not be able to use it for every BB device model. I don't know why RIM put it in SDK samples. By doing that RIM pushes developers to a wrong way. As alishaik786 mentiones a proper method of taking images on BB is using Invoke.invokeApplication(Invoke.APP_TYPE_CAMERA, new CameraArguments()) with a FileSystemJournalListener implementation. Just search on StackOverflow on these for the implementation details. I vaguely recall the implementation is painful (like many other parts on BB), but once done it will work on any device.
you got two error
1."javax.microedition.media.MediaException: There is already another active Player. Call Player.close()
this exception thrown if you try to open camera (player) while another instance of camera is already opened. In your code, you need to define the player object as a class level and must close the player after taking the snapshot (also need to close the player if you push from one screen to another).
2."Error Class Java.lang.ArrayIndexOutOfBoundsException: Index 0>=0"
This error may occur when you access encoding array while encoding array size is zero.
You can ensure this issue by using _videoControl.getSnapshot( null), which take the snapshot in default encoding.
So first insure these issue and reply me.
