问题 I have a widget I'm trying to build that consists of only a button. What I'm wanting to do is have the button clicked and then run some simple piece of code (in my test it's a toast alert). It seems to work fine initially, but suddenly the button stops responding to clicks. I've noticed it consistently after the phone has been asleep. Here is my code for the AppWidgetProvider. onUpdate: for (int appWidgetId : appWidgetIds) { RemoteViews remoteView = new RemoteViews(context.getPackageName(), R

问题 I want to listen to touch events for a viewFlipper. I've been able to listen to touch events in my activity and then modify the viewFlipper but these events are fired wherever the user is within the activity and I need to capture touch events specifically on the viewFlipper. I have tried adding setOnTouchListener but it is not called. I'm assuming the viewFlippers children (webviews) are 'consuming' the touch events. One solution would be to setOnTouchListener's to each of the webviews but

问题 Just like in texting applications, I want the keyboard to push the dialog box up when it raises. The issue I'm currently having is that the keyboard actually raises over my dialog box and the screen does not scroll. Here's what I want: (Don't have enough reputation to post images) Image one (Before) Image two (After) See how nicely it raises? How do I go about doing that? 回答1: Use a RelativeLayout and place your EditText using android:layout_alignParentBottom="true" it should then raise

问题 I am adding linearlayouts to GridLayout dynamically. I want that to be displayed like grid view. Is it possible to calculate how many linear layouts can be placed in one row and set column count for grid layout or i should use gridview to align them automatically. 回答1: If you want to calculate the column count based on the width of the GridLayout , override the onMeasure method. It provides widthSpec and heightSpec as parameters, from which you can get the actual width and height in pixels

问题 I'm trying to make work a self-updating functionality in an Android widget, something simple as changing two TextViews of it every 10 seconds. The ideal solution would be to make it similar to the genie widget (news & weather). And so far, it works okay: it updates every 10 seconds via Handler.postDelayed's Runnable. Runnable updateWidgetText = new Runnable() { @Override public void run() { if (screenEnabled) { AppWidgetManager gm = AppWidgetManager.getInstance(ctx); ComponentName thisWidget

问题 I have got my main.xml as follows: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:text="TextView" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView> <ListView android:layout_height="wrap_content" android:id="@+id/listView1" android:layout_width=

问题 I'm developing a widget for my app and I'd like to pass specific data from the widget to the app. The user can add multiple versions of the widget and I need to detect which widget it is coming from so I can show specific information in the app. What I have works so far, but only if I exit my app completely (repeatedly pressing the back button), otherwise it doesn't seem to be detecting the data being passed in. This the code I have to pass the data from the widget to the app: public class

问题 I have a ListView that must display 4 items at a time. And I must scroll one item, one by one. After user scrolls the ListView, I must readjust the scroll to fit 4 items. I mean, I can´t show an item by half. Another question, is there any way to get the current ListView scrollY offset? Because the listView.getScrollY() method is from View, but not the Scroller object inside the ListView. 回答1: I've found an excellent solution. It works perfect for me. May be my answer will help someone. class

Here's my code: ImageSwitcher mImageSwitcher; mImageSwitcher = new ImageSwitcher(this); mImageSwitcher.setLayoutParams(new ImageSwitcher.LayoutParams( LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT)); mImageSwitcher.setInAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_in)); mImageSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_out)); mImageSwitcher.setFactory(this)
