You can do this by sending an intent for the image gallery.
first fire the intent:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
 
startActivityForResult(i, 1);
 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

with this code you fire an intent to open the imagegallery.
and you start the activity to get a result (your image)

After this you got to capture the result (the selected image) from the imagegallery:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
//implement the onActivity for result method
 
        protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
 
                super.onActivityResult(requestCode, resultCode, intent);
 
                        if(resultCode == RESULT_OK){  
 
                            Uri selectedImage = intent.getData();  
 
                            String [] proj={MediaStore.Images.Media.DATA};
 
                            Cursor cursor = managedQuery(selectedImage,proj,null,null,null);  
 
                            int column_index = cursor.getColumnIndexOrThrow(proj[0]);
 
                            cursor.moveToNext(); 
 
                            String filePath = cursor.getString(column_index);
 
                            bitmap = BitmapFactory.decodeFile(filePath);
 
 //bitmap = youre image
 
                        }
 
                        else if (resultCode == RESULT_CANCELED) {
 
                        }
 
                }

I have the same problem.
I have an ImageView and a Button
I want to click on a button and the "file browser" is open for browser image file. and then the ImageView will display the choosen image file.

So have I to add this to Button listener?

Code: Select all: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI); startActivityForResult(i, 1);

and then, where to call the "protected void onActivityResult" ?
thanks you.
