How can I make make a border for a clicked imagebutton in Android? -


I am using Imagebuttons to show some icons in my Android project. 

  & lt; Android: layout_height = "wrap_content" android: layout_alignParentLeft = "true" Android: layout_alignParentTop = "true" Android: padding = "20dp" Android: contentDescription = "@ String / button_on" Android: background = "@ Android: color / transparent" Android: src = "@drawable / button_on" />

I think, when the button is in a pressed state, there will be a white border with rounded corners. What can I do to do this? Can this just be used on code or will I need an extra background image?

This is a method if you do not want to create separate images with the border

Make Drawable XML with your border style (e.g., border.xml) 

   & Lt; Padding android: left = "1dp" android: top = "1dp" Android: right = "1dp" Android: Below = "1dp" /> & Lt; Corners Android: bottomRightRadius = "8dip" Android: bottomLeftRadius = "8dip" Android: topRightRadius = "8dip" Android: topLeftRadius = "8dip" /> & Lt; / Size & gt;

Make selector drawable (eg some_selector_name.xml). When pressed basically, it will show your border painting. Otherwise, it would be transparent. 

  & lt; Selector xmlns: android = "http://schemas.android.com/apk/res/android" & gt; & Lt; Item Android: state_pressed = "true" android: drawable = "@ drawable / border" /> & Lt; Item android: drawable = "@ android: color / transparent" /> & Lt; / Selector & gt;

Set your background of your image button to drawable your selector 

; ImageButton Android :. Android: layout_width = "wrap_content" android: layout_height = "wrap_content" Android: layout_alignParentLeft = "true" Android: layout_alignParentTop = "true" Android: padding = "20dp" Android: Content Circles = "@ String / button_one "Android: background =" @ drawable / some_seller_name.exml "Android: src =" @drawable / button_on "/>

Now when you press the button, it should display the white border. This is just an example but you should get this idea.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
