The following is the ScanDialogFragment.
public class ScanDialogFragment extends DialogFragment
{
public ScanDialogFragment()
{
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup
container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.scanningdialogview,
container);
return view;
}
}
This is the XML for the scanningdialogview layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical">
<ProgressBar
android:id="@+id/scanningProgress"
android:gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<TextView
android:id="@+id/textView1"
android:layout_width="252dp"
android:layout_height="match_parent"
android:gravity="center_horizontal|center_vertical"
android:text="@string/scanning_message"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
<TextView
android:id="@+id/statusTextItem"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="end"
android:gravity="center_horizontal"
android:text="@string/standby_message"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
The strings for "scanning_message" and "standby_message" are simple
strings "Scanning..." and "One Moment Please...", the latter of which
should be getting updated in the dialog with the current information
item as the service performs its duties. The dialog appears and
disappears on cue, and the scanning service and thread does its job just
fine.
Thank you,
