Inside my android application, I need to create a function inside a class MyAdapter which is used inside the Activity MyActivity (which is not the MainActivity). The function should have the following structure
public int getDrawableResourceId(String name) {
// naive explanation
return R.drawable. + name
}
For example if I call getDrawableResorceId("test") it should return the integer value of R.drawable.test. I cannot work with int drawableResourceId = getResources().getIdentifier(name, "drawable", getPackageName()); because Android Studio tells me that cannot resolve the methods getResources() and getPackageName(). If I replace it with
int drawableResourceId = MyActivity.this
.getResources()
.getIdentifier(name, "drawable", MyActivity.this.getPackageName());
or
int drawableResourceId = MainActivity.this
.getResources()
.getIdentifier(name, "drawable", MainActivity.this.getPackageName());
Android Studio tells me that the Activity is not an enclosing class. That is why I directly want to cast the String into R.drawable.name.
Sorry I edited my answer, got the wrong question in mind:
public static int getDrawable(Context context, String name) {
return context.getResources().getIdentifier(name, "drawable", context.getPackageName());
}
Update *
Since you are in an Adapter let's say you have MyAdapter as class name do:
public class MyAdapter{
private Context mContext;
public MyAdapter(Context context){
mContext = context;
}
....
Then below you can easily call:
getDrawable(mContext, "name")
