Re: [android-developers] Re: How to get only one restaurant when I press click button one click

[abeer shlby]

I write this lines of code under button but it not working why
can you help me in this code
You could storage the parsed ArrayList, make a global variable for counting
the number of times that the button has been clicked.
ArrayList venuesList; Button btn; int clickCount; //
ArrayList allResults; List shownResults = new
ArrayList(); ArrayAdapter  myAdapter; @Override protected
void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);
new fourquare().execute(); btn=(Button) findViewById(R.id.button);
btn.setonclickListener(new View.onclickListener() { @Override public void
onclick(View v) { String name = venuesList.get(clickCount).getName();
String cat = venuesList.get(clickCount).getCategory(); String city =
venuesList.get(clickCount).getCity(); shownResults.add(name + "," + "cat" +
"" + city); clickCount++; myAdapter.notifyDataSetChanged(); } }); }
