Body

First, the question

1.1 First Look at the problem code:

@Override
PublicView GetView (intPosition, View Convertview, ViewGroup parent) {
if(Convertview = =NULL) {
Convertview = Layoutinflater.from (Getactivity ()). Inflate (R.layout.fragment_feed_grid_item, parent,false);
Convertview.findviewbyid (R.id.avatar). Setonclicklistener (NewView.onclicklistener () {
@Override
PublicvoidOnClick (View v) {
//startactivity
}
});
}

Convertview.setlayoutparams (Newgridview.layoutparams (MWINDOWWIDTH/3, MWIDOWWIDTH/3));

//other Code
returnConvertview;
}

The purpose of the code is to dynamically set the size of the item within the GridView according to the width of the screen, which is naturally written.

1.2 Specific symptoms

1.2.1 The first item of the ImageView display is not complete, always show half, the other item no problem, such as how to set up is useless

1.2.2 The Click event set in the first item does not work, but a gentle scrolling of the Click event immediately takes effect.

Ii. Solutions

@Override
PublicView GetView (intPosition, View Convertview, ViewGroup parent) {
if(Convertview = =NULL) {
Convertview = Layoutinflater.from (Getactivity ()). Inflate (R.layout.fragment_feed_grid_item, parent,false);
Convertview.setlayoutparams (Newgridview.layoutparams (MWINDOWWIDTH/3, MWINDOWWIDTH/3));
Convertview.findviewbyid (R.id.user_avatar). Setonclicklistener (NewView.onclicklistener () {
@Override
Public voidOnClick (View v) {
//startactivity
}
});
}

//other Code
returnConvertview;
}

As above.
