How to Load an Image from Gallery in ImageEditor Xamarin.Android?
Description:
This article explains you to load an Image from Gallery to the Image Editor.
Solution:
- Create a Xamarin application and initialize SfImageEditor control in it by using the below code.
Import the SfImageEditor as shown below,
using Syncfusion.SfImageEditor.Android; |
C#
static Intent mainIntent; private static int SELECT_FROM_GALLERY = 0; internal static string Path { get; set; } SfImageEditor editor;
protected override void OnCreate(Bundle bundle) { base.OnCreate(bundle); editor = new SfImageEditor(this); SetContentView(editor);
} |
- Load an Image from Gallery to the image editor by call the InitializeMediaPicker method as shown in below.
C#
public void InitializeMediaPicker()
{
Intent = new Intent();
Intent.SetType("image/*");
Intent.SetAction(Intent.ActionGetContent);
StartActivityForResult(Intent.CreateChooser(Intent, "Select Picture"), SELECT_FROM_GALLERY);
}
private string GetPathToImage(Android.Net.Uri uri)
{
string imgId = "";
using (var c1 = ContentResolver.Query(uri, null, null, null, null))
{
c1.MoveToFirst();
string imageId = c1.GetString(0);
imgId = imageId.Substring(imageId.LastIndexOf(":") + 1);
}
string path = null;
string selection = MediaStore.Images.Media.InterfaceConsts.Id + " =? ";
using (var cursor = ContentResolver.Query(MediaStore.Images.Media.ExternalContentUri, null, selection, new string[] { imgId }, null))
{
if (cursor == null) return path;
var columnIndex = cursor.GetColumnIndexOrThrow(MediaStore.Images.Media.InterfaceConsts.Data);
cursor.MoveToFirst();
path = cursor.GetString(columnIndex);
}
return path;
}
- Set the Captured image from Camera to the ImageEditor as Bitmap Only. So you need to set the Bitmap as shown in below
protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
{
if (data == null) data = mainIntent;
if ((resultCode != Result.Ok) || (data == null))
{
return;
}
if (resultCode == Result.Ok)
{
var uri = data.Data;
if (requestCode == SELECT_FROM_GALLERY)
{
try
{
Path = GetPathToImage(uri);
editor.Bitmap = BitmapFactory.DecodeFile(Path);
}
catch (Exception ex)
{
}
}
else return;
}
}
