I have built my interface by using ViewStubs, which I inflate during onCreate.
But later in my app, I want to change the View completely, by loading different View into the same place. How do I achieve that?

I have an audio player toolbar activity that has a corresponding layout file.
I need this player to show up at the bottom of another activity. I use a ViewStub and inflate the audio toolbar's layout file in the stub.
How do I access the buttons, etc on this inflated view and how do I set their behavior?
The docs on ViewStub did not mention anything about this (or maybe I totally overlooked something).
I need to replace the current View (set by the activity.setContentView method) by an other.

View 2 Replies View RelatedI've got ~200 png files in the /res/drawable folder, mostly interface and sprite sheet stuff. They're all indexed pngs, and weigh in at a grand total of a bit over 400kb.
When I run aapt to package them into the apk, their filesize nearly doubles. Opening the apk up with 7zip and extracting the drawables confirms it: 790kb.
Does anyone have any idea why this would be happening? I thought the packaging process was meant to compress the pngs, not inflate them!
I created a layout xml file that contains an extended textview. What I want is to draw the textview in a bitmap. What do I have to do after inflating the view so that I can use the draw method on the my canvas?

My code to inflate the view seems to work fine, except that the attributes of the ImageView are not applied.Specifically, the inflated ImageView does not have the width/height that I set for it via the android:layout params in XML.Can someone show me what I'm doing wrong?I want to set the width/height of the image in dp, so that it is the correct size across multiple screen dpis and support Android 1.5+.
View 2 Replies View RelatedI have an activity which extends TabActivity and implements TabContentFactory. For simplicity's sake I'll limit the problem to 1 tab.
In onCreate() I do this:
CODE:..........
In createTabContent:
CODE:...........
So far, so great. I get the tab, the layout is displayed.
I also have a button in the layout, so I do:
CODE:.............
And then I subscribe to it's click event:
CODE:..........
Now, here's the problem. I click the button and nothing happens. I can for example execute the following code from elsewhere:
CODE:.............
And the button will get disabled, but when I tap it (in its *enabled* state) - nothing happens.
If I'm not, could it be that I have another tab, where the another inflated copy of the same layout is displayed? However, in this layout's button's OnClickListener nothing happens as well.
I have made a Custom Component in XML, consisting of a button with an imageview stacked on top of it:
<myapp.widget.ClearableCaptionedButton
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="@+id/ccbutton_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical|left"
android:textAppearance="?android:attr/textAppearanceMedium"
android:background="@android:drawable/edit_text"/>
<ImageView
android:id="@+id/ccbutton_clear"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dip"
android:layout_alignRight="@id/ccbutton_button"
android:layout_alignTop="@id/ccbutton_button"
android:layout_alignBottom="@id/ccbutton_button"/>
</myapp.widget.ClearableCaptionedButton>
Extract of java source code:
public class ClearableCaptionedButton extends RelativeLayout implements OnClickListener {
...
public ClearableCaptionedButton(Context context, AttributeSet attrs) { super(context, attrs);
// some stuff that works fine
} ..
protected void onFinishInflate() { super.onFinishInflate();
mButton = (Button) findViewById(R.id.ccbutton_button);
mClear = (ImageView) findViewById(R.id.ccbutton_clear);
mButton.setText(""); // error here: mButton == null
}
My problem is similar to this one. When I try to find the views inside the custom compound, findViewById returns null. But, as you can see, i already added super(context, attrs); to the constructor. I am using the custom component directly in xml layout, like this:
<LinearLayout>
<!-- some stuff -->
<myapp.widget.ClearableCaptionedButton
android:layout_width="fill_parent"
android:layout_height="wrap_content"
app:caption="to"/>
</LinearLayout>
Im using an inflater inside an adapter for my listview. I need to add in a different button depending in the state of the data for each row, so Im thinking I need to do this programmatically, but how do I make sure its inserted into the correct place inside the layout?
View 1 Replies View RelatedWhile researching how to create custom compound views in Android, I have come across this pattern a lot (example comes from the Jteam blog)I mostly understand how this is working, except for the part where inflate() is called. The documentation says that this method returns a View object, but in this example the author does not store the result anywhere. After inflation, how is the new View created fromt eh XML associated with this class? I thought about assigning it to "this", but that seems very wrong.
View 1 Replies View RelatedI have Eclipse Juno and I'm working on an app with that.
The main activity will have a scrollable menu that takes you to all the other activities.
So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.
Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)
- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
- Item ??: Centred, bold, non selectable title (Tools)
- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.
I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.
I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.
I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C
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);.............

I use my daytimer more so as a notebook than for planning my day. I use my outlook/android calendar to keep track of appointments. I mainly use my daytimer to keep track of things that occur during the day or things I need to remember for later that day. I also keep track of time I worked at a specific client so I have it when I go through later in the week and prepare invoices. So, is there an app that would work well for that? I am thinking some kind of journal program maybe.

View 49 Replies View RelatedIf you're like me, you find the new soft keyboard in Android 1.5 difficult to use and slow to type on. The keys are too small, the corrections suck, and the word predictions just aren't that great. It's nothing compared to the slick and intuitive keyboard on the iPhone.
Let's say there was a market app that replaces the keyboard with something much better. I'm talking something with high accuracy corrections and predictions, something that adapts to your typing style as you type, and has a fantastic UI for corrections and predictions. Let's say it increases your average typing speed by a factor of 2x.
Up to how much would you be willing to pay for the app?
I'm talking about something much better even than this, typing software, fast text entry - WordLogic Predictive Keyboard, which costs $24.95.
I know I've had some apps specifically tell me that if I have a shortcut to them on a home screen, I need to delete the old one and replace it after an update. Does that apply to all apps, or only those that specifically say the shortcut needs updating? A related question is why would ANY app require changing a shortcut? Unless an update moves the location of an app, what else could change? Necessary
