Finally, the new activity should have been added to the AndroidManifest.xml file and designated as the launcher activity. The manifest file can be found in the project window under the app -> manifests folder and should contain the following XML:
<googlehtmlet>BUY_ANDROID_STUDIO6androidstudio_a6</googlehtmlet>
<pre>
<?xml version="1.0" encoding="utf-8"?>
From within the Widgets palette category, drag a Button view object into the center of the display view. Note that green horizontal and vertical dashed lines appear to indicate the center axes of the display. Once centered, release the mouse button to drop the view into position. Click and drag a Plain Text object from the Text Fields section of the palette and position it so that it appears above the button as illustrated in Figure 16 2:

<?xml version="1.0" encoding="utf-8"?>

This declaration should be followed by the root element of the layout, typically a container view such as a layout manager. This is represented by both opening and closing tags and any properties that need to be set on the view. The following XML, for example, declares a RelativeLayout view as the root element and sets match_parent properties such that it fills all the available space of the device display with padding on each side of 64 density independent pixels:

While it is possible to zoom in and out of the tree view using the scale at the bottom of the panel or by spinning the mouse wheel, in most cases the tree will be too large to view entirely within the Tree View panel. To move the view window around the tree simply click and drag in the Tree View panel, or move the lens within the Tree Overview panel (Figure 16-5):
