Body
You can add an "extra" to the Intent that you use to start the second activity. This "extra" could contain information about the state of the buttons. In the <code>onCreate()</code> of the second activity, you can examine the information in the "extra" and set the backgrounds of the buttons accordingly. EDIT: Add example code I would create a boolean variable for each button, indicating the state of the background and add this to each activity, like this: <pre><code>private boolean button1Checked; private boolean button2Checked; </code></pre> Then, whenever you change the background color, you change the state of the appropriate variable: <pre><code>if (...) { button2.setBackgroundResource(...); button2Checked = true; // or false, whatever } </code></pre> Then, when you want to start activity2, you add the state of the 2 buttons as extras to the Intent, like this: <pre><code>Intent intent=new Intent (this, second_activity.class); // use "this" instead of getApplicationContext() intent.putExtra("button1Checked", button1Checked); intent.putExtra("button1Checked", button2Checked); startActivity(intent); </code></pre> Now, in <code>onCreate()</code> of the second activity, you recover the state of the buttons from the passed extras, like this: <pre><code>button1 = (Button) .... button1Checked = getIntent().getBooleanExtra("button1Checked", false); if (button1Checked) { button1.setBackgroundResource(...); // true state } else { button1.setBackgroundResource(...); // false state } button2 = (Button) .... button2Checked = getIntent().getBooleanExtra("button2Checked", false); if (button2Checked) { button2.setBackgroundResource(...); // true state } else { button2.setBackgroundResource(...); // false state } </code></pre> Hopefully you get the idea.

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.
