I have a table in which i have one column where pictures names like R.drawable.pic101
, R.drawable.pic2
are saved. Now retrieving from database im storing theses names in an ArrayList
of String
. Now to setImageResource
these names should be in Integer
ArrayList
.. Now i need to convert ArrayList
of String
to ArrayList
of Integer
. Please give me a possible solution.
You can save your ArrayList with resources ID as an integer, to get resources with string names you need to obtain its identifiers:
private Integer getResourceByString(Context context, String name) {
return context.getResources().getIdentifier(name, "drawable", context.getPackageName());
}
Or you could also set directly the desired Drawable to the ImageView:
private void setStringResourceImageView(ImageView imageView, String name) {
Context context = imageView.getContext();
Integer resId = context.getResources().getIdentifier(name, "drawable", context.getPackageName());
imageView.setImageResource(resId);
}
