All geek questions in one place

Why are my items in the ListView not accessible?

Elements in my list do not change. I tried getcurrentfocus () and blocked the descendants in the RelativeLayout tag in content_palce.xml. All I want from the list consists of two functions:

  • When I click an item, another action is triggered.
  • A long press displays a context menu.

Update 1:

I added an onitemclick listener, but .. this did not work. The list can be scrolled, but not clicked. When you click on the list, feedback will be shown. If you have a clicker, something will happen ... if you do nothing, but it still detects a click. This does not happen in my case. It seems tg click was not detected.

Android does not allow you to select list items that have focusable items in the Item layout.

disable focus in layout elements

Android: focus = false

add the code you want to execute by clicking inside the click listen button inside getView

public View getView(int position, View convertView, ViewGroup parent) {

View vi = convertView;

vi.setOnClickListener(new View.OnClickListener() {

 @Override
public void onClick(View v) {
