Android : Put Custom View Above Built In Views In Droid?

Mar 11, 2010

I am developing a small app for Android. I am creating my own view.

I am planning to design the layout to be:

<LinearLayout>
<MyView>
<Button><Button>
</LinearLayout>

But when I run my program, my custom view will cover the whole screen. Is there anyway to avoid this?

I have already tried to add android:layout_width, layout_height to be wrap_content, fill_partent, but no luck.

Android :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background

Jan 6, 2010

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.

The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.

The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.

What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

Android :: Using TabHost With Dynamically Built - Pre-existing Views

May 25, 2009

I have a remove assistant app, which allows customers to perform a subset of functions of a desktop application, untethered. Results are communicated back & forth via messages left at a license server. In order to have a single source for the logic of the assistant, yet run on multiple platforms (Swing, MIDP, & Android), I write a driver composed of Database, Network, & Display pieces.

The Android driver is nearly complete, but I run into a brick wall when it comes to Tabs. All views are instanced calling code, not XML defined. I already have the view before I try to add it.

I tried sub- classing TabHost:

CODE:.................

As is shown in the code, it errors in setup. Looking further down in setup() I will also get this exception too: Your TabHost must have a FrameLayout whose id attribute is 'android.R.id.tabcontent

Is there a way to trick setup() into instancing me mTabWidget & mTabContent members?

Android :: Putting Views On Top Of Other View

Feb 9, 2010

I'm still trying to figure out how best to layer views on top of other views. I want to do something like the ZoomButtons on top of a custom view. I tried getting the ZoomButtonsController's parent and then adding views, but I didn't have enough control and they ended up on top of the buttons. I've gotten close by using a FrameLayout and some gravity on the top two views. But this has some interesting effects. Since this is contained with a tab, these two top views appear on top of all four of the tab pages. I want them on top of one of those pages only. Apparently, nested FrameLayouts don't mix well. What is the proper and expected way to do this? Here is more or less my complete layout....................

Android :: Adding Views To Another View

Oct 9, 2010

Is there a possibility to add a view or derivative (button, textview, imageview etc...) to another view without having to go through layouts?

I have a class called ScreenView, it derives from View (e.g. public class ScreenView extends View).
I wanted to display text into it, labels, images etc..

On an iPhone it's trivial, simply create my objects and use addSubview method ; you can embed any UI objects into another. Most UI toolkits work that way too.

Problem with layouts is that I haven't found an easy way to properly position a subview (say a text view) in a given location of the enclosing View. I want one to contain the other...

I was hoping I had missed something in the documentation (which is far from being intuitive that's for sure) and I could do something like myView.addView(subview). But it ain't so :)

As a side question, what is the closest to iPhone's UILabel in the Android world?
A UILabel can contain a text or a graphic. Right now I've been using TextView and ImageView but they aren't anywhere as flexible when it comes to layout as a UILabel

Edit: Making my View inherit from ViewGoup instead, let me add subview..
However, I want to draw in my view. I found that when ScreenView extends ViewGroup, the onDraw function is never called then.

Something like:

CODE:..........

Would paint in yellow my view if ScreenView extends View ; but not if it extends ViewGroup.

How do you draw directly in the view then?

General :: Built A Custom Kernel For Phone

Apr 26, 2012

I'm trying to make a custom kernel for the Samsung Gravity SMART using sources from the unofficial CM9 port for the Gio/Ace (which both use very similar hardware to the Gravity Smart). What I've succeeded at so far:

1) Acquiring the source, both for the CM9 kernel and for the stock Froyo kernel
2) Searching for the device-dependent references in the stock kernel
3) Porting those changes over to the CM9 kernel
4) Getting everything to actually compile
5) Acquiring the stock CM7.2 source
6) Creating device makefiles (i.e. BoardConfig.mk, etc)
7) Building CM7.2 using kernel built in step #4
8) Putting the various img files into an Odin-compatible .tar.md5
9) Actually flashing to the phone.

And for all that work, I got.. a soft-bricked phone (fortunately, I have an Odin file for stock firmware). The phone boots to a SAMSUNG logo (not flashing/throbbing). how the heck do I figure out what's actually failing? Is there a bootloader to unlock, and if so how do I unlock it?

Android :: Views In Custom Compound Component Not Inflated

Jun 12, 2010

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>

Android :: Add Custom Views To Linear Layout Object

May 31, 2010

I have a set of custom views that I would like to add to a LinearLayout object. However, the first object I add to the layout (I do this dynamically, during runtime) has a OnMeasure method that tries to get as much space as possible resulting in that it get's all the space LinearLayout object. This is correct behavior, but when I then add more objects following that I want the allocated area for the first object to decrease so the others will fit. As it is now, each following object will get zero space, and hence won't be visible.

Android :: Custom Control Or Make Views Inline?

Dec 22, 2009

I have a requirement to create a control similar to UITabBar in iPhone, which is to be present on every activity of my application. UITabBar essentially is a battery of buttons exhibiting a TAB like behavior: every button maps to an activity. I have two solutions for this: 1. In the layout XML for every activity, I insert a <LinearLayout><Button/><Button/><Button/></LinearLayout> element. And then have a common listener class that will handle the button clicks. So, every activity will have an instance of this listener. 2. To create a custom Widget extending LinearLayout class, put all the buttons as its static members and let it handle the button clicks. Include this custom control in every screen.

Android :: Keeping References To Inflated Custom Views

Apr 26, 2010

While 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.

Android :: Way To Add A View To Overlap Other Views In Layout / Activity?

Apr 19, 2009

Is it possible to add a view dynamically that overlaps other views in the layout. I have Linear Layout defined for the activity. As part of the Layout I have a custom View. The content changes dynamically and sizes appropriately based on the content size, with fill_parent for width and wrap_content for height. But what I want is, dynamically take over the full screen and then based on a click go back to the normal mode. Is there a mode to display a view where - in it can overlap all other views in the layout?

Android :: Custom View Extending View-Class / Still Based On XML-Layout

Aug 17, 2010

I want to build my own custom view which should look like the Crysis-GUI.At first I designed a XML-based Layout and made it visible via the setContentView(int resid)-Method. Worked pretty well.But now I wan't to go a step further and draw in my Layout. So I created a new Class, let it extend View and overrode the onDraw()-Method. 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?

Android : How To Display A Custom View In Droid

Aug 30, 2010

I am generating a custom View that contains a number of drawables that are added to the View dynamically. This means the View's size could be anything, and is likely to stretch off the screen. Where it does stretch off the screen I want scrolling to be enabled.

So far I have tried:

adding the custom view directly to my Activity - this displays the drawables ok, but with no scrolling
adding the custom view as a child to a ScrollView and setting the ScrollView as the content in the Activity - this doesn't display anything.

How do I generate a custom view of arbitrary size, display it and have scrolling where it is too big for the screen?

Android :: Prevent Custom Views From Losing State Across Screen Orientation Changes

Aug 22, 2010

I've successfully implemented onRetainNonConfigurationInstance() for my main activity to save and restore certain critical components across screen orientation changes.

But it seems, my custom views are being re-created from scratch when the orientation changes. This makes sense, although in my case it's inconvenient because the custom view in question is an X/Y plot and the plotted points are stored in the custom view.

Is there a crafty way to implement something similar to onRetainNonConfigurationInstance() for a custom view, or do I need to just implement methods in the custom view which allow me to get and set its "state"?
