Answer 1

Use this method:

 list.setOnItemClickListener(new AdapterView.onItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
      Intent appInfo = new Intent(YourActivity.this, ApkInfoActivity.class);
       startActivity(appInfo);
   } 
});

A good place to put your click code would be on the Listview Adapter. In your Adapter (Customlistview in your case) put a code similar to this:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
  View view = LayoutInflater.from(context).inflate(R.layout.seu_layout, null);
  view.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View view) {
      this.minhaLista.get(position); // Aqui você vai obter o item selecionado e com ele as informações que você quiser
      Intent intent = new Intent(context, NewsActivity.class);
      intent.putExtra("position", "qualquer coisa que você queira passar");
      Toast toast = Toast.makeText(this, "A mensagem que você quer", 500);
      toast.show();
      context.startActivity(intent);
     }
     return view;
 }

Something similar to the one above. Anyway take a look at this: https://blog.alura.com.br/personalizando-uma-listview-no-android/

And also consider switching to something more current if possible, a Recycleview for example: http://mobimais.com.br/blog/recyclerview-android-tutorial-facil/
