When I create a dialog upon a Button click, I get an error. How can I show a dialog upon a Button click?

Question

My main class extends Activity.

            deleteentry.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    new deleteOptionsDialog(getApplicationContext()).show();
                }
            });
    public class deleteOptionsDialog extends Dialog {

            public deleteOptionsDialog(final Context context) {
                super(context, android.R.style.Theme_Translucent);

                requestWindowFeature(Window.FEATURE_NO_TITLE);
                setContentView(R.layout.delete_options_dialog);

                RelativeLayout cameraLayout = (RelativeLayout) findViewById(R.id.rldelete);
                cameraLayout.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub

                    }
                });

            }

replace

new deleteOptionsDialog(getApplicationContext()).show();

with

new deleteOptionsDialog(YourActivity.this).show();

and try to move all your code inside Constructor to onCreate() method of Dialog by overriding it.

For Dialog instance you should use Activity context, not getApplicationContext() and not getApplication(), but YourActivity.this

And it's a better idea to instanciate dialog somewhere in onCreate() an later check if it is showing when trying to show once more
