<p>your help is appreciate.</p> <p>===EDIT FOR SOLUTION.STATUS CLOSED===</p> <p>thank you for those who helped me a lot with this. this is my final solution. i need to make SpinnerAdapter first to retrieved the context of the spinner selected.</p> <p>i also followed tutorial from <a href="http://developer.android.com/guide/topics/ui/controls/spinner.html" rel="nofollow">here</a></p> <p>my last code would be</p> <pre><code>genderSpin = (Spinner)findViewById(R.id.gender_spin); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.genderArray, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); genderSpin.setAdapter(adapter); genderSpin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { public void onItemSelected(AdapterView<?> parent, View arg1, int pos, long arg3){ String fontname = parent.getItemAtPosition(pos).toString(); Toast.makeText(parent.getContext(), "The External Font Is " +fontname, Toast.LENGTH_LONG).show(); } @Override public void onNothingSelected(AdapterView<?> arg0) { // TODO Auto-generated method stub } }); </code></pre> <p>after selected spinner item, it will toast out "The External Font Is Female" if choosing female and toast out "The External Font Is Male" if choosing male. Thank you for the helped. Hope this could be good guidance for those who seeking for the help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
