Aug 2, 2010I 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){

View 1 Replies View RelatedAndroid :: Having Offscreen Drawing Of A View
May 26, 2010I'm having a small problem with drawing a View offscreen to a Bitmap. The View is created using LayoutInflater.inflate(int resource, ViewGroup root) with null passed to the root parameter. The View has a fixed size (200x180 pixels). I can create a Bitmap for this View either by using the method View.getDrawingCache() or by calling View.draw(Canvas canvas) using a Canvas that in turn has a backing Bitmap. This works fine if the View doesn't change after the inflate. However, if I have a TextView inside my View that I will update, the size of the TextView is never updated regardless of what method I call on the View (requestLayout(), forceLayout() invalidate() etc.). If I display the View on screen directly, everything works fine (sizes are updated as needed, etc.). What is the correct way of drawing Views off screen and being able to update their layout when needed?
View 3 Replies View RelatedAndroid :: Why Drawing In View Not Take Effect?
Mar 31, 2009I'm trying to create a custom widget which looks lick HTML table. I chose to derive from TableLayout, which is the subclass of ViewGroup and View. What's confusing me is that the drawing I put into my override of View.onDraw did not take effect, until I moved the codes to the override of ViewGroup.dispatchDraw. I know dispatchDraw is a good place to draw something, but I'm just wondering why there's such difference in my practice?
View 3 Replies View RelatedAndroid :: Custom Overlay Item Not Drawing
Aug 10, 2010I created a custom OverlayItem class so that I could essentially have one kind of OverlayItem whose Drawable marker would set itself depending on the state of some data that I pass into it. I have attempted to accomplish this by, on my first attempt, utilizing the setMarker method within the OverlayItem class. Once that did not work I attempt to override the getMarker method and have it return the appropriate marker to represent the data. Both of these attempts ended with nothing being drawn on the map...however if they are commented out the markers draw just fine (except they of course use the default marker, which isn't what I want). Here is my code for my custom OverlayItem class (the commented out methods I have tried and they have not worked):
private class MyOverlayItem extends OverlayItem {
private Context mContext; private MyData mData;
public MyOverlayItem(GeoPoint point, MyData data, Context context) {
super(point, data.getWhat(), data.getWhere()); this.mContext = context; this.mData = data;
/*if(data.getTemp() > 200) this.setMarker(res.getDrawable(R.drawable.icon_data_hot_l));
else if(data.getTemp() > 100) this.setMarker(res.getDrawable(R.drawable.icon_data_neutral_l));
else this.setMarker(res.getDrawable(R.drawable.icon_data_frozen_l));*/ }
/*@Override public Drawable getMarker(int stateBitset) {
Resources res = this.mContext.getResources(); if(this.mData.getTemp() > 200)
return res.getDrawable(R.drawable.icon_data_hot_l); else if(this.mData.getTemp() > 100)
return res.getDrawable(R.drawable.icon_data_neutral_l);
return res.getDrawable(R.drawable.icon_data_frozen_l);
}*/ }
Is there a way to do what I am attempting to do or do I need to make a unique OverlayItem class corresponding to each state of my data?

View 2 Replies View RelatedAndroid :: Drawing Focus Highlight In Custom Widget
Jul 6, 2009I have made a custom widget, very similar to JTable in Swing. It is not editable, and all data is replaced at once, allowing easy checking for the widest item in each column & custom col sizing at replace time. It is a subclass of LinearLayout, filled with re-usable TableRow Objects, sub-classed directly from View.
TableRow is both Clickable, focusable, & focusable In Touch Mode. TableRow overrides onDraw(Canvas), calling super. It draws the first column in Black with Lt gray underneath. If the TableRow isFocused () , then a filled rectangle is drawn, before the rest of the cols (left or right justified based on data type), and borders. Where do I get the color, orange, to draw the filled rectangle indicating focus? android.R.drawable.list_selector_background seems to be a pointer, value 17301602, not an actual color. Placing any real Color in my code draws things fine. Is this 17301602 transparent or something? Am I doing this wrong, or do I just need to know how to fine the orange?

View 10 Replies View RelatedAndroid :: Drag And Drop Functionality / Custom Drawing
Apr 8, 2010I am working on something that needed custom drag-and-drop functionality, so I have been subclassing View, doing a bunch of math in response to touch events, and then rendering everything manually through code on the canvas in onDraw. Now, the more functionality I add, the more the code is growing out of control and I find myself writing a ton more code than I would expect to write in a high level environment like Android.
Is this how it's done, or am I missing something? If I'm not doing anything fancy in the UI, the framework handles the majority of my interactions. Built-in controls handle the touches and drags, and my code is pretty much limited to business logic and data. Is there a way to leverage the power of some of the UI controls and things like animations while also doing some of it manually in the onDraw canvas? Is there an accepted standard of when to use one or the other (if indeed the two approaches can be mixed)?
Android :: View Get Drawing Cache Method Always Returns Null
May 12, 2010I'm working with Android 2.1 and have the following problem:
Using the method View.getDrawingCache() always returns null. getDrawingCache() should return a Bitmap, which is the presentation of View's content.
Example code:
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final View view = findViewById(R.id.ImageView01);
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
final Bitmap bmp = view.getDrawingCache();
System.out.println(bmp);
}
I've already tried different ways to configure the View object for generating the drawing cache (e.g. View.setWillNotDraw(boolean) and View.setWillNotCacheDrawing(boolean)), but nothing works. What is the right way, or what I'm doing wrong? In real code I want to apply getDrawingCache() on a ViewGroup like RelativeLayout. Is the behaviour the same when using a ViewGroup?
Android :: Custom View Extending View-Class / Still Based On XML-Layout

So far so good.But how can I still use my XML-Layout? I can't do setContentView anymore, so how could the same effect be achieved?

Nov 3, 2010I 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).

View 2 Replies View RelatedAndroid :: Style Own Styleable With A Style - Custom View Class With Custom Attribute
Jul 8, 2009I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
