android - PopupMenu button not working -

I have a button in the activity when I click on a button then it displays the popup menu. I need to show the gallery in the page below. But the IM error is happening. " ConstructorManactivity.IJAadapter (New popup menu.OnMainiteClickList () {}) is undefined "

Code:

main.xml: & lt; Relative layout xmlns: Android = "http://schemas.android.com/apk/res/android" xmlns: tools = "http://schemas.android.com/toolsAndroid: mess =" @ dimen / activity_vertical_margin "Android : PaddingLeft = "@ dimen / activity_horizontal_margin" Android: paddingRight = "@ dimen / activity_horizontal_margin" Android: paddingTop = "Android: @ daemon / activity_version_mergin" tools: reference = ".

 gallery.setAdapter (New ImageAdapter (this)); The "This" popup menu item in the above row of your code is a symbol of the click listener, while the constructor requires an application context in the image adapter class. Bottom line gallery. Try to give context primarily as SetAdapter (New ImageAdapter (MainActivity.This).);
