我正在开发一种由服务器接收有关事件数据的星体应用。
In a ListView I put the name and category of the event and a picture. My problem is: each category should have a specific picture. How do I choose which of the pictures in the drawable folder should be displayed?
View v; /**I get this view from the parameters.**/
ImageView iconCategory = (ImageView) v .findViewById(R.id.category_icon);
Drawable drawable = null;
if (o.getCategoria().equals("category1")) {
/* here I want to set the icon to the file named icon_category1.png . I wanna do that by instantiating drawable */
} else if (o.getCategoria().equals("category2")) {
/* here I want to set the icon to the file named icon_category2.png I wanna do that by instantiating drawable */
} else if (o.getCategoria().equals("category3")) {
/* here I want to set the icon to the file named icon_category3.png I wanna do that by instantiating drawable */
}
iconCategory.setImageDrawable(drawable);
