I am trying to set the visibility for a button as follows:
public Bundle setActivityState(Bundle bundle){
startBtn = (Button) findViewById(R.id.startSensorsBtn);
startBtn.setVisibility(
getVisibilityState(bundle, PersistanceConstants.START_BTN_STATE)
);
return bundle;
}
public int getVisibilityState(Bundle bundle, String keyName){
if (bundle.getInt(keyName) == View.VISIBLE){
return View.VISIBLE;
} else if (bundle.getInt(keyName) == View.INVISIBLE){
return View.INVISIBLE;
} else if (bundle.getInt(keyName) == View.GONE){
return View.GONE;
}
return 0;
}
But I am getting the error:
Must be one of: View.VISIBLE, View.INVISIBLE, View.GONE less... (Ctrl+F1)
Reports two types of problems:
- Supplying the wrong type of resource identifier. For example, when calling Resources.getString(int id), you should be passing R.string.something, not R.drawable.something.
- Passing the wrong constant to a method which expects one of a specific set of constants. For example, when calling View#setLayoutDirection, the parameter must be android.view.View.LAYOUT_DIRECTION_LTR or android.view.View.LAYOUT_DIRECTION_RTL.
while calling
getVisibilityState(bundle, PersistanceConstants.START_BTN_STATE)
I don't know how to get around this. I understand that it's expecting a given set of values but all I know is to pass an int
to it. What can be done here?
When you know what you're doing, you can suppress this Android Studio inspection locally with
//noinspection ResourceType
For example,
//noinspection ResourceType
startBtn.setVisibility(bundle.getInt(PersistanceConstants.START_BTN_STATE));
A bit late to the party but another solution if you are using this a lot in your code and you have a method returning that int is to define your own Visibility annotation, so something like this:
public class MyStuff {
@IntDef({View.VISIBLE, View.INVISIBLE, View.GONE})
@Retention(RetentionPolicy.SOURCE)
public @interface Visibility {
}
public @Visibility int getVisibility() {
return View.GONE;
}
}
If you do so then AS won't complain anymore because you are returning a proper int def.
