Hi I'm trying to develop an application which runs for every interval time, lets say for every 1 minute it will display some <code>Toast message</code>. But problem is I'm using <code>RadioButton</code> functionality is perfect but when I tap on one radio button it will be green, but when I close and re-open the activity I'll get as none of the radio buttons selected. Here is my <code>MainActivity.java</code> <pre><code>public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void onRadioButtonClicked(View view) { // Is the button now checked? boolean checked = ((RadioButton) view).isChecked(); // Check which radio button was clicked switch(view.getId()) { case R.id.radio_one_min: if (checked) { //some code } break; case R.id.radio_ten_min: if (checked) { //some code } break; case R.id.radio_disable: if (checked) { //some code } break; } } } </code></pre> and here is my <code>activity_main.xml</code> <pre><code><?xml version="1.0" encoding="utf-8"?> <RadioGroup xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:id="@+id/radio"> <RadioButton android:id="@+id/radio_disable" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Disable" android:onClick="onRadioButtonClicked"/> <RadioButton android:id="@+id/radio_one_min" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1 minute" android:onClick="onRadioButtonClicked"/> <RadioButton android:id="@+id/radio_ten_min" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="10 minute" android:onClick="onRadioButtonClicked"/> </RadioGroup> </code></pre> Please help me to solve this riddle. Thanks in advance...

Guidance

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.
