Show alertDialog with radiobuttons when click a listViewItem

The error is clearly explanatory, you are missing a semicolon
. Your code should be like
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3)
{
AlertDialogView();
}//ERROR I'm GETTING HERE is Syntax error, insert ";" to complete Statement
};
and the above code should be inside the onCreate()
. In the code that you provided, its floating in the middle of nowhere!

I have a listView with 2 items in it, the 2 items are "seconds" and "minutes" When I press "seconds" I'd like a alertDialogBox to open en show 5,10,15,... seconds. Same when I press minutes
Something like this:
But I'm having trouble implementing it, because I don't understand very well how it is working. Here is the code I have:
import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast; public class SettingsActivity extends Activity { ListView listView = (ListView) findViewById(R.id.settingsList); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.settings); String[] values = new String[] { "Seconds", "Minutes" }; // Define a new Adapter // First parameter - Context // Second parameter - Layout for the row // Third parameter - ID of the TextView to which the data is written // Forth - the Array of data ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, values); // Assign adapter to ListView listView.setAdapter(adapter); listView.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) { AlertDialogView(); } }); } private void AlertDialogView() { final CharSequence[] items = { "15 secs", "30 secs", "1 min", "2 mins" }; AlertDialog.Builder builder = new AlertDialog.Builder(ShowDialog.this);//ERROR ShowDialog cannot be resolved to a type builder.setTitle("Alert Dialog with ListView and Radio button"); builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int item) { Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show(); } }); builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { Toast.makeText(ShowDialog.this, "Success", Toast.LENGTH_SHORT) .show(); } }); builder.setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { Toast.makeText(ShowDialog.this, "Fail", Toast.LENGTH_SHORT) .show(); } }); AlertDialog alert = builder.create(); alert.show(); } }

mXX about 11 yearsI changed the code, how stupid of me... But I'm still getting the error on the showDialogBox. How come? The error is
ShowDialog cannot be resolved to a type

ElefantPhace about 11 yearsIt would be better if you'd post the logcat so we can see what you're talking about

mXX about 11 yearsNot possible, I can't compile because I'm having errors. Logcat is empty

Antrromet about 11 yearsInstead of ShowDialog.this it should be the context. There is no such thing called as ShowDialog. It should be SettingsActivity.this instead.
