    <p>I have an widget, with an button and an imagebutton. I want that if you click the imagebutton, there opens an transparant activity with an edittext. For example we fill in 01 Than when you click the normal button, it will load an webview that shows html file 01.html. Is this possible?</p> <p>The code i have is:</p> <pre><code> package com.kerk.liedboek.widget; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.appwidget.AppWidgetManager; import android.appwidget.AppWidgetProvider; import android.content.Context; import android.content.Intent; import android.util.Log; import android.widget.RemoteViews; import android.widget.Toast; public class main extends AppWidgetProvider { public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget"; public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget"; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Intent i = new Intent(context, edit.class); PendingIntent pi = PendingIntent.getBroadcast(context,0, i,0); RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.main); rv.setOnClickPendingIntent(R.id.button_one, pi); Intent i2 = new Intent(context, webview.class); PendingIntent pi2 = PendingIntent.getBroadcast(context,0, i2,0); RemoteViews rv2 = new RemoteViews(context.getPackageName(), R.layout.main); rv2.setOnClickPendingIntent(R.id.button_two, pi2); } } </code></pre> <p>I'm new to android, and i now i'm an newb.

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).
