    <p>I havean Activity_A which has a Log-out option. On clicking that I call the Log-in Activity. So when i Click device back button when i am on Login-in Activity it takes me back to the Activity_A where i have the log-out option. what i wanted is, when i click device back button when i am on log-in Activity it must take me to the device home screen. something like "close application" or "clear activity stack".</p> <p>I tried this:</p> <pre><code>Intent intent = new Intent(Activity_A.this, LoginActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); </code></pre> <p>but it didn't work, i also tried using finish() int the above code, then it takes me to the Activity i called before Activity_A (as expected).</p> <p>I searched for my case, and could not find a perfect solution, can someone please help me achieve what i wanted?</p> <p>and i have an idea of overriding device back button onClick in my login Activity so that it shows the home screen of the device and clears all the activity stack....is it possible? if yes, is it safe?</p> <p>This is what i have done in LoginActivity, which works just like i wanted</p> <pre><code>public void onBackPressed() { // TODO Auto-generated method stub super.onBackPressed(); Intent startMain = new Intent(Intent.ACTION_MAIN); startMain.addCategory(Intent.CATEGORY_HOME); startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(startMain); } </code></pre> <p>But is there any other way to achieve this without overriding onBackPressed()??</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.
