    <p>I use ActionBarSherlock (although I don't think it matters).</p> <p>I have a Main activity and an About activity. I want the About activity to show the back-arrow by its logo, and do the proper animation and such. I don't know how to do this properly.</p> <p>Currently, I have under onOptionsMenuItemSelected to launch the Main activity when the Up/Home button is pressed, but it's hacky and doesn't really work right. It plays the wrong animation, and handles multitasking poorly.</p> <p>How do I set this up right?</p> <p>Here's the part in my Main activity that launches the About:</p> <pre><code>Intent aboutIntent = new Intent(MainActivity.this, About.class); MainActivity.this.startActivity(aboutIntent); </code></pre> <p>Here's my About activity:</p> <pre><code>package com.stevenschoen.test; import android.content.Intent; import android.os.Bundle; import com.actionbarsherlock.app.SherlockActivity; import com.actionbarsherlock.view.MenuItem; public class About extends SherlockActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.about); getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setDisplayShowTitleEnabled(false); } public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // app icon in action bar clicked; go home Intent intentHome = new Intent(this, MainActivity.class); intentHome.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intentHome); return true; default: return super.onOptionsItemSelected(item); } } } </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
