如何根据字符串变量按名称获取资源？

Question

我想做

String childImg = "childIcon";
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.????, 0, 0, 0);

它期待一个int，但我有一个字符串。我该如何解决这个问题？

Answer 1

我用它来获得drawable id

getResources().getIdentifier(childImg, "drawable", getPackageName())

Answer 2

使用getIdentifier()

int id = getResources().getIdentifier("name_of_resource", "id", getPackageName());

Answer 3

这样做：

String childImg = "childIcon";
int id = getResources().getIdentifier(childImg, "drawable", getPackageName())
textView.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0);

Answer 4

textView.setCompoundDrawablesWithIntrinsicBounds(Resources.getIdentifier(childImg), 0, 0, 0);
