Android如何检查对象的类型
The instanceof operator compares an object to a specified type. You can use it to test if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.
示例代码:
void checkforTextView(View v)
{ if(v instanceof TextView)
{ // This is a TextView control }
else
{ // This is not a TextView control } }
