Mengecek Apakah Sebuah Method ada dalam Class
Berikut ini adalah contoh kode untuk mengecek apakah sebuah method ada dalam class. Dalam hal ini, yang dicari adalah setRotation yang belum disupport oleh widget ImageView di android 2.2 dan sudah disupport oleh android 3.0
for(Method m: ImageView.getClass().getMethods() )
{
String mymethod = "setRotation";
if(mymethod.equalsIgnoreCase(m.getName()))
{
holder.imgListItem.setRotation( (float) item.rotation);
}
}
