我想要做

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？

我用它来获取可绘制的 id

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

采用getIdentifier()

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

像这样做：

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