@Overridepublic voidonCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);

setContentView(R.layout.main);

Button buttonLoadImage=(Button) findViewById(R.id.buttonLoadPicture);

buttonLoadImage.setOnClickListener(newView.OnClickListener() {

@Overridepublic voidonClick(View arg0) {

Intent i= newIntent(

Intent.ACTION_PICK,

android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

startActivityForResult(i, RESULT_LOAD_IMAGE);

}

});

}

@Overrideprotected void onActivityResult(int requestCode, intresultCode, 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));

}
