Android :: Populate View Flipper Child View With List View?

Aug 2, 2010

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:

The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

Android :: Populating View Flipper Child View

Aug 2, 2010

I am trying to populate a ViewFlipper with a ListView when a certain button is clicked...but I only get a NullPointerException for lv.setAdapter(new ArrayAdapter<String>(this, R.layout.specialeffectsview, specialEffects)); To be honest I don't really know how to do this, I just learned about the ViewFlipper today and I haven't fully understood how to use it yet. If anyone could help me find how what I have done wrong, that would be great.

Here is the code I use:
public void onClick(View v){ if (v == btnExposure){
mFlipper.setDisplayedChild(0);
else if (v == btnProperties){ mFlipper.setDisplayedChild(1); }
else if (v == btnSpecialEffects){ mFlipper.setDisplayedChild(2); String[] specialEffects = getResources().getStringArray(R.array.special_effects_array); lv.setAdapter(new ArrayAdapter<String>(this, R.layout.specialeffectsview, specialEffects)); lv.setChoiceMode(ListView.CHOICE_MODE_SINGLE); }

I have a WebView inside the ScrollView. The content of WebView dyanamically changes when it displays different html page. I have the following issue: For example I have A.html, and B.html. The content of B.html is larger than A.html, so the page is longer.

May 18, 2010

I have a HorizontalScrollView with a series of CompoundButtons. I want to find the (x,y) for a given child view. I have tried using:

getLocationOnScreen()

tmpView.getLocalVisibleRect(hitRect);
the hitRect is always 0,0 - 0,0.

Android :: Multi Column Custom List View / With Editable Edit Text At End Of List View

Nov 3, 2010

I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

Android :: Combining Map View And List View In Application

Aug 4, 2010

I am working on an application where I need to display some locations on a map and in a list view where the user should be able to toggle between these views(activities?). I want the toggle button(s) to be in my custom titlebar like in the images (if they are attached). What is the best practice for this? Tab view seems like a solution but can I customize the tab buttons? Should the map and list be in different activities or the same? Now I have two different activities one extending MapActivity and one extending ListActivity but no way to toggle between them. Is it possible to load activities into a FrameLayout?
