Body
I am building and android app and have created the login screen. The next screen will show the logged in user a set of options from which he has to choose one. The second activity is started from the <code>onPostExecute</code> method of an <code>AsyncTask</code> using the <code>startActivity(intent)</code> code. <pre><code>Intent intent = null; intent = new Intent(context, DisplayMessageActivity.class); context.startActivity(intent); </code></pre> I am trying to build the UI for this screen using the .xml file <code>activity_display_message.xml</code>. The entry for this has been made to the manifest file. Any of the layout attributes that I am specifying in this .xml file are not getting applied. Any help in this regard is highly appreciated. For example using the code below I am unable to get the background color that I have set. This works fine with the .xml that I have for my main activity. The onCreate function for my DisplayMessageActivity class is <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_display_message); Intent intent = getIntent(); String message = intent.getStringExtra(CommonStaticValues.EXTRA_MESSAGE); TextView textView = new TextView(this); textView.setTextSize(40); textView.setText(message); setContentView(textView); } </code></pre> The complete <code>activity_display_message.xml</code> file is <pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/background_color"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:text="@string/hello_world" tools:context=".DisplayMessageActivity" /> </RelativeLayout> </code></pre>

Guidance

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.
