问题 I'm trying just some very simple code to get an Android widget going but with no luck. I've looked around everywhere and haven't found a good answer. All I want (for now) is to increment a counter when the widget is touched and display the current value. This is my AppWidgetProvider: public class WordWidget extends AppWidgetProvider { Integer touchCounter = 0; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { //This is run when a new

问题 Is there any way to change the color of the ProgressBar residing in the app widget at runtime? This is how the ProgressBar progress value is updated: RemoteViews views = new RemoteViews( context.getPackageName(), R.layout.widget ); views.setProgressBar( R.id.progressbar, 100, 10, false ); ... appWidgetManager.updateAppWidget( widgetID, views ); Unfortunately, the RemoteViews class does not allow us to set a color filter or even a different progress drawable for ProgressBar . Any ideas would

问题 Dear all, I am trying to set the position of a TextView within an appwidget. Basically, the direct access to properties af the TextView works: myRemoteView.setTextColor(R.id.myTextView, Color.WHITE); //works Also indirectly, I can access the TextView properties: myRemoteView.setInt(R.id.myTextView, "setTextColor", Color.BLUE); // works And setting float values also works: myRemoteView.setFloat(R.id.myTextView, "setTextSize", 25); // works Now I'm trying to shift the x position of the TextView

问题 I am having an unexpected bothering issue with a remote listview. My app has a simple widget which includes a listview. If the listview has 1 cell height and the listview is at the beginning of its scroll it blinks/flahses everytime datasetchanged is called. The funny thing is that if the listview has more than 1 cell height or if it has 1 cell height BUT it has been scrolled down a bit it doesnt blink. Could anybody please provide some suggestion? I am frustrated. Solutions I have thought so

问题 My app widget needs to be configured when it first added to the home screen. I want to open a configuration view right after the user adds the widget. AppWidgetProvider has no onCreated event, so I'm showing the confugration activity on the onUpdate event, and store a boolean value in SharedConfiguration that marks that the configuration has already been shown. Is there an easier way? 回答1: In the AppWidgetProvider XML file there is an attribute called android:configure You can use this to

问题 I have a bit of a strange bug with a widget I've coded- after the screen rotates the widget stops responding to onClick events. The code is exactly the same as in the Android Developer Documentation for App Widgets here. I've noticed other widgets from the market don't have this problem- is there a known workaround perhaps? I've tried tapping all over the place after a rotation so I don't think its the onClickPendingIntent not being resized after a rotation; it doesn't seem to be present at

问题 I've created a widget which displays a simple textview, which is editable as an Edittext in a configuration activity. I save the inputted text with shared preferences, so the user can tap the widget to edit the text, and the already inputted text appears in the edittextfield. My problem is this. I would like the user to be able to add multiple widgets, but when a seccond widget is added, the same text as in the other widget is loaded from shared preferences. And, when on widget is edited so

问题 I'm trying to create a digital clock widget with a custom font. And this has proven to be the biggest challenge of my Android experience. (Thought it would be as simple as tc.setTypeFace("whatever") and be done with it) The best way seems to be scratch the TextClock and use an ImageView and pass a Bitmap to it using a custom AlarmManager to create a new image for the view each second. Before I get into the Bitmap generation, I practiced on a simple TextView using this tutorial Alarm Manager

问题 I'm playing around building a new widget and was looking at the Android app widget documentation, in particular the section on which widget classes were supported. I noticed that ViewFlipper is supported, but I'm struggling to find any examples on how to use one in a home screen widget. In particular, I'm wondering if its possible to manually trigger swapping views. In an activity this looks relatively straightforward, one example being hooking up the onclick listener of a button to call the
