How can I check if a View is visible (android listview)

I've created a library that allows user to download images in background and put it in a View, passed by argument to a function, when download is finished. The problem is that if I use my library in a listview, calling this method in the getView() method, when a user scroll very fast, the library do a request for each row passed. But I'd like to do it, only when a cell is really visible by user... maybe when the scroll list is stopped. So, how can I check this thing on the single view that I pass to the library method? Thaaanks

You can use

  1. getVisibility () Returns the visibility status for this view .

  2. isShown () Returns the visibility of this view and all of its ancestors .

getVisibility()

 if (ViewObj.getVisibility() == View.VISIBLE) {
    // Your Staff
} else {
   // Your Staff
}

isShown ()

True if this view and all of its ancestors are VISIBLE

You can use view.getVisibility(). The result will be View.VISIBLE, View.GONEor View.INVISIBLE.

If you want to do something when your view is visible, then your expected result will be: View.VISIBLE 

if(yourView.getVisibility() == View.VISIBLE){
//Do what you want..
}
