Java的：

Greetings! I want to receive the list of the established appendices in the Android. But the list is displayed only in LogCat. How to write, that it was displayed on phone?I use the given code:java:

    ArrayList<ResolveInfo> list = (ArrayList<ResolveInfo>)
    pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);

    android:layout_height="fill_parent">
<TextView
    android:id="@+id/textSelest"

List pkgAppsList = context.getPackageManager().getInstalledPackages();
