    <p>I have problems about updating child view in ViewFlipper when I use the ViewFlipper as the Widget.</p> <p>Here are layout for Widgets:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" &gt; &lt;TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:text="Widget Title" android:textAppearance="?android:attr/textAppearanceMedium" /&gt; &lt;Button android:id="@+id/refresh_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="Refresh" /&gt; &lt;ViewFlipper android:id="@+id/viewflipper" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@id/refresh_button" android:autoStart="true" android:inAnimation="@anim/in_from_bottom" android:outAnimation="@anim/out_from_top" android:flipInterval="10000" &gt; &lt;TextView android:name="@+id/test1" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#FF00FF" android:text="test1" /&gt; &lt;TextView android:name="@+id/test2" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#00FF00" android:text="test2" /&gt; &lt;/ViewFlipper&gt; </code></pre> <p></p> <p>And Here is the AppWidgetProvider:</p> <pre><code>package com.example.filperwidget; import android.app.PendingIntent; import android.appwidget.AppWidgetManager; import android.appwidget.AppWidgetProvider; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.widget.RemoteViews; import android.widget.Toast; public class FilperWidgetProvider extends AppWidgetProvider { private static final String TAG = FilperWidgetProvider.class.getSimpleName(); private static final String REFRESH_ACTION = "com.example.fliperwidget.REFRESH"; private RemoteViews mRemoteViews; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { for (int i = 0; i &lt; appWidgetIds.length; i++) { int widgetId = appWidgetIds[i]; RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout); remoteViews.setTextViewText(R.id.test1, "flipper"); initRefreshButton(context, remoteViews, widgetId); mRemoteViews = remoteViews; appWidgetManager.updateAppWidget(widgetId, remoteViews); } super.onUpdate(context, appWidgetManager, appWidgetIds); } private void initRefreshButton(Context context, RemoteViews remoteViews, int appWidgetId) { // Bind the click intent for the refresh button on the widget final Intent refreshIntent = new Intent(context, FilperWidgetProvider.class); refreshIntent.setAction(FilperWidgetProvider.REFRESH_ACTION); refreshIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); final PendingIntent refreshPendingIntent = PendingIntent.getBroadcast( context, 0, refreshIntent, PendingIntent.FLAG_UPDATE_CURRENT); remoteViews.setOnClickPendingIntent(R.id.refresh_button, refreshPendingIntent); } @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (action.equals(REFRESH_ACTION)) { Toast.makeText(context, "Refreash is clicked", Toast.LENGTH_SHORT) .show(); RemoteViews remoteViews = mRemoteViews; if (mRemoteViews == null) { WidgetLog.d(TAG, "mRemoteViews == null"); remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout); } final ComponentName cn = new ComponentName(context, FilperWidgetProvider.class); AppWidgetManager appWidgetManager = AppWidgetManager .getInstance(context); // appWidgetManager.updateAppWidget(appWidgetId, views); // remoteViews.setTextViewText(R.id.test1, "Click Test"); remoteViews.setCharSequence(R.id.test1, "setText", "Test Test"); remoteViews.setTextViewText(R.id.test2, "Click Test2"); remoteViews.setTextViewText(R.id.title, "Test"); int id = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1); remoteViews.showNext(R.id.viewflipper); appWidgetManager.updateAppWidget(id, remoteViews); appWidgetManager.updateAppWidget(cn, remoteViews); } super.onReceive(context, intent); } } </code></pre> <p>As you can see, when I update the Widget Title, it can work. But When I want to update the subView of Flipper (Text1/Text2), It doesn't work-The text is not changed. The <code>showNext()</code> also work correctly. So anyone can help for that? Thanks in advance.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
