    <p>I am trying to make this simple Dialog semi-transparent:</p> <pre><code>class TestDialog extends SherlockDialogFragment { public TestDialog() { super(); } @Override public Dialog onCreateDialog(Bundle savedInstanceStateBundle ) { AlertDialog.Builder builder1 = new AlertDialog.Builder(getActivity()); // Get the layout inflater LayoutInflater inflater1 = getActivity().getLayoutInflater(); // Inflate and set the layout for the dialog // Pass null as the parent view because its going in the dialog layout builder1.setView(inflater1.inflate(R.layout.dlg_test, null)) // Add action buttons .setPositiveButton( "Ok", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { // sign in the user ... } }) .setNegativeButton( "Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { } }); return builder1.create(); } } </code></pre> <p>The Layout is the following:</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/username" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="16dp" android:layout_marginLeft="4dp" android:layout_marginRight="4dp" android:layout_marginBottom="4dp" android:hint="User name" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>I have tried everything, from using a transparent .png as the background drawable of the linear layout, to setting the alpha field to 0.5, to using as a drawable a color equal to 0. I am not able to make that dialog semi-transparent. I don't know even if it is possible. What i would like to create is a dialog like the panel in the following image: <img src="https://i.stack.imgur.com/Xchct.jpg" alt="semi-transparent control panel">. Thanks. Note1: the min sdk required is version 8, the target is the latest (actually, v17).</p>

    1. COI think this may depend on the SDK version. In 1.6 dialogs are semi-transparent by default but try `AlertDialog.Builder(Context context, int theme)` where theme is `android.R.style.Theme_Dialog.

    2. COHave you tried using something like `android:background="#4000"` in the the XML? (#4000 is ARGB_4444 colorspace).

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.

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