How to set some item unclickable in GridView

For example, I need to judge the contents of the item in the Item can be clicked.
enter image description here
As shown in the picture, I need to get the gray Item cannot be clicked.
Here is my adapter

}

return mDatas.get(position);
}

return position;
}
#Override

I set view.setClickable (false)in my Adapter, but it does not work.

item.setEnabled(false);
when u need to make it clickable call
item.setEnabled(true);
Here item is your edittext or button or anything else
Try this:
if (room.getRoom_status().equals("0") &&room.getRoomType().getRoom_type_name().equals("0")) {
view.setBackgroundResource(R.drawable.single);
view.setEnabled(false);
} else if (room.getRoom_status().equals("1") && room.getRoomType().getRoom_type_name().equals("0")) {
view.setBackgroundResource(R.drawable.single_b);
} else if (room.getRoom_status().equals("1") && room.getRoomType().getRoom_type_name().equals("1")) {
view.setBackgroundResource(R.drawable.double_b);
} else if(room.getRoom_status().equals("0") && room.getRoomType().getRoom_type_name().equals("1")){
view.setEnabled(false);
view.setBackgroundResource(R.drawable.doubleg);
}
else
view.setEnabled(true);

The right way is to write a Boolean value, and let it based on a Boolean value to determine whether to jump.
private boolean checkedIntent = false;
if (roomstate.equals("0") && roomtype.equals("0")) {
checkedIntent = false;
} else if (roomstate.equals("1") && roomtype.equals("0")) {
checkedIntent = true;
} else if (roomstate.equals("1") && roomtype.equals("1")) {
checkedIntent = true;
} else if (roomstate.equals("0") && roomtype.equals("1")) {
checkedIntent = false;
}
if (checkedIntent == true) {
Intent intent = new Intent(RoomList.this, BookRoomDetail.class);
intent.putExtras(mBundle);
startActivity(intent);
}

Android - Creating Listview using Custom Adapter Programmatically

I'm in learning about add view programmatically. But, I'm in confusing now.
I have data, there are idpatient, idheader. Patient can have more than one ID header. When I input idpatient, it will add listview (with custom adapter) programmatically. The number of listview is same with the number of ID header.
I want to set in each listview with data patient group by ID header..
So far, I add search view when loop adding listview, but when I input one ID header to seacrh view, all of listview will view the same data according to ID header in search view..
I'm sorry for the long explanation. Can anybody help me to solve this problem?
Thanks in advance

setOnScrollListener of ListView interrupts setOnItemClickListener

It took me two(!) days to figure out my problem.
I have ListView with both onItemClickListener and onScrollListner. If I implement the onScrollListner then no ItemClick actions are fired.
I saw this problem here: setOnScrollListener with setOnItemClickListener and here:Android: cannot set both: setOnItemClickListener setOnScrollListener? with no real solution.
I have also noticed (in the emulator) that when one of the rows (in the ListView) is selected then ItemClick does fire (I assume that it works in not touch mode).
Very frustrating, can anyone think of a solution?
Some code:

In "theory"^^ everything works (appendList Log return correct value), but i as say i have problem with update ShowsAdapter (Download new image + and insert content to ListView)
