    <p>I have a <code>WebView</code> I add to an <code>Activity</code> with <code>setContentView()</code>. In this <code>WebView</code> I have a button that opens another <code>Activity</code> on top of the current one (using <code>startActivityForResult()</code>), this <code>Activity</code> dismisses itself after finishing its task, and we return to the first <code>Activity</code> (The one with the <code>WebView</code>). When returning to the <code>Activity</code> the <code>WebView</code> vanishes for a moment and we see the <code>Activity</code>'s background (it comes back after a second). This is annoying and looks glitchy. I'm not really sure why it happens, but it has something to do with invalidation of the <code>WebView</code> and it being <code>INVISIBLE</code> for a second (This is probably the way android renders its views or something...). Is there a fix for this?</p> <p>This behavior only happens when hardware acceleration is enabled, disabling it fixes the issue, but I need hardware acceleration for the <code>WebView</code>.</p> <p><strong>EDIT</strong>: Some code</p> <pre><code>// A self dismissing activity public class TestActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ImageView v = new ImageView(getApplicationContext()); v.setBackgroundColor(0xFFFF0000); setContentView(v); Handler handler = new Handler(Looper.getMainLooper()); handler.postDelayed(new Runnable() { @Override public void run() { TestActivity.this.finish(); } }, 1000); } } // Code to show the WebView and then the activity, stick this somewhere in a different Activity WebView wv = new WebView(getApplicationContext()); wv.loadUrl("www.google.com"); addContentView(wv, new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT)); (new Handler(Looper.getMainLooper())).postDelayed(new Runnable() { @Override public void run() { Intent I = new Intent(getApplicationContext(), TestActivity.class); startActivityForResult(I, 255); } }, 1000); </code></pre> <p>This is much simpler than my actual code, but it replicates the result nicely.</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.
