VISIBLE alone is nothing so you are getting VISIBLE cannot be resolved to a variable
.
Just use View.VISIBLE
to resolve it to that type.
VISIBLE:
int android.view.View.VISIBLE = 0 [0x0]
public static final int VISIBLE
题
I am getting a compiler error in my class for the constant "VISIBLE" that I am trying to use in the following example
if((enterIP.getVisibility()).equals(VISIBLE)){
the compiler error is, "VISIBLE cannot be resolved to a variable"
from the Android documentation
public int getVisibility()
Added in API level 1 Returns the visibility status for this view.
Related XML Attributes android:visibility Returns One of VISIBLE, INVISIBLE, or GONE.
how do I get the numerical value of VISIBLE or how can I use it in the example I showed?

其他提示
use
if((enterIP.getVisibility()).equals(View.VISIBLE)) {
}
instead of
if((enterIP.getVisibility()).equals(VISIBLE)){
}
because VISIBLE
is constant inside View
class or you can use any View like Button,TextView to access constants from View class like enterIP.VISIBLE
VISIBLE, INVISIBLE and GONE are attributes of your enterIP View, so you would use it like this:
if((enterIP.getVisibility()).equals(enterIP.VISIBLE)){
You have to use
View.VISIBLE
Then may be you can solve the error.
I have commented the reason why you are facing the compile time error. But if you still want to do the same has you are trying to do we can do the following.
declare the variables globally
public static final int INVISIBLE=View.INVISIBLE;
public static final int VISIBLE=View.VISIBLE;
public static final int GONE=View.GONE;
and then use you code
if((enterIP.getVisibility()).equals(VISIBLE)){
Now the error seems to be gone.
Note: Done this way avoid calling "View" class each and every time.
Hope this helps you.
