Android :: Setup A Background Png On View And Anchor It To Top Not Scale In Droid?
Aug 24, 2009
I have an image, say 16px from our designer. I want to Set it as the background image on a view, but the view is larger than the image. So I want to anchor the image at the top of the view, and then have the view fill in the bottom with a solid color.
Is this possible in the current version of android, 1.5_r3?
Here is what I have so far, but the image is scaling to take up the entire view, and I am not sure how to set the image as background and specify a solid color at the same time. I suspect I need to wrap the view in a containing view which has the color specified, is that the best way to do it? code...

I'm battling with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.
Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.

I've created a custom ViewGroup (based off of the Launcher) that allows paging scrolls between some WebViews. Problem is that it doesn't scroll as smoothly as I want it to. I've been following Romain Guy's 2008 advice, but I don't see any massive improvements. Is it because I am using WebViews, or am I just doing the prescaling wrong? This is my code:
Bitmap originalImage = BitmapFactory.decodeResource(getResources(), R.drawable.redbg);
originalImage = Bitmap.createScaledBitmap( originalImage, // bitmap to resize ((WindowManager)
getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getWidth(),
// new width ((WindowManager)getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay().getHeight(), // new height true); // bilinear filtering
getWindow().setBackgroundDrawable(new BitmapDrawable(originalImage));
called from onCreate. Is the right?

On a layout I want to scale the background image (keeping its aspect ratio) to the space allocated when the page gets created. I am using layout.setBackgroundDrawable() and am using a BitmapDrawable to setGravity for clipping and filling, but don't see any option for scaling.

How can I set the scaling in a web view (or any view at all)? I have a box of 200 and 200, for example. If I apply a web view to it, a web view bigger than the box, it will give me scrollbars. I am seeking for a way to scale the content in order for the webView to fit the box.
Assume that I know the dimesions of the box, and ALSO the dimensions of the WebView.

I have a custom view which is drawing some bitmaps on screen. I want to scale the bitmaps depending on some sensor data. Can anyone suggest to me the best way (performance wise) to scale the bitmaps.
Right now I'm creating the bitmaps in the constructor of the view but if I start to scale it in the onDraw method I believe I'll just be re-drawing the bitmaps (Which will be a memory / cpu hog).

Is it possible to set the absolute position of a view in android? (I know that there is an AbsoluteLayout, but it's deprecated...)
Lets say I have a screen 240x320px, and I want to put an ImageView which is 20x20px with its center at the position (100,100).
What do I have to do?

How do you animate the change of background color of a view in Android?
For example:
I have a view with a red background color. The background color of the view changes to blue. How can I do a smooth transition between colors?
If this can't be done with views, an alternative will be welcome.

I want to be able to specify an android:src, but I want android:background="" - complaints that string types are not allowed when compiling.
I basically want a button without any background (but that *does* have a 'src').

I have an XMl file like below which I will use to set background for Textview:
row.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
The above Xml I will set as background for TextView in main.xml as below:
main.xml
<TextView
android:id="@+id/rowtext3"
android:text="Availablity"
android:layout_height="25px"
android:layout_width="60px"
android:textSize="10px"
android:textStyle="bold"
android:textColor="@color/black"
android:gravity="center"
android:background="@drawable/row"/>
But I want this to do from code rather than Xml.I have done everything that I have done in Xml like font,width,Height,font dynamically through code , but not able to set Background that I mentioned in Xml file . How can we set content of Xml file as background to textview similar to how we set background as XML in main.xml.
In the code I have done like this:
t1=new TextView(this);
t1.setText(ed1.getText());
t1.setHeight(25);
t1.setWidth(60);
t1.setTextSize(10);
But I didn't find how to set background i.e. how to set XML content as background?

I have, for the time being, a custom view with a 9-patch image as a border.
That custom view is placed three times in a LinearLayout, so it looks like this:
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.
So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.
So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.

How do I set up an xml layout where an OpenGL view is part of it? As I do now is set the OpenGL view as the only view with setContentView(). But I would like to create an xml layout that includes the OpenGL view. Lets say I want to have the OpenGL view mainly and a small TextView at the bottom.
Is this even possible? Or can an OpenGL view only be the one and only view?
