Android :: SurfaceView Vs Custom View / SurfaceView Is Slower
Aug 20, 2010One using a Surfaceview, and the other using a custom view. According to the android SDK development guide, using a surface view is better because you can spawn a separate thread to handle graphics. Th SDK development guide claims that using a custom view with invalidate calls is only good for slower animations, less intense graphics.However, in my simple app, I can clearly see that using a custom view with calls to invalidate seems to render faster.What do you guys know/think about this?My touchEvent code is exactly the same, and my drawing code is exactly the same. The only difference is that one is all in the UI thread, and the other is using a tread to handle the drawing.

Aug 24, 2009I 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...

Android : Transparent Background Overlay Of SurfaceView Broken On 1.5?
Jun 17, 2009I believe I have found a graphics bug introduced in the 1.5 platform. I'm looking for some confirmation (or a description of what I'm doing wrong) before reporting it as a real bug.
I have a SurfaceView that fills the screen and on top of that I have a LinearLayout that wraps some other components that overlay the surface. These other components are not visible most of the time, and the LinearLayout has a transparent background so that the SurfaceView is unobstructed until the other components are made visible. Under 1.0 and 1.1 this all worked with a background of #00000000 for the LinearLayout. Now under 1.5 there is a black rectangle obstructing my surface unless I give the LinearLayout background some color. I can still keep the transparency so it is still invisible as it should be but it is strange that it can't be black and invisible anymore. My layout is below. The background of #00000001 works, but changing it to #00000000 results in a black rectangle. code...

View 2 Replies View RelatedAndroid :: Adding GestureOverlayView To My SurfaceView Class - How To Add To View Hierarchy
Jul 30, 2010I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness.
I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc .
This all works great.
I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have
CODE:..........
The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:
CODE:................
So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.
Android :: Adding View Extending From SurfaceView To Layout Gives Blank Screen
Jun 5, 2010I'm very new to Android programming, so this is probably something pretty basic. I just have an xml layout with a few buttons. I'm trying to follow the model given by the JetBoy demo, so I'm adding a view to the layout which extends SurfaceView. When this new view is put in my xml layout, I just get a blank screen.
Here's the XML layout if it helps. The gameview element is what causes the screen to be blank

Android :: Setup Background Of A TextView Dynamically From Xml File?
Oct 10, 2010I 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?

Android :: View On Press Onpress - Change Background Color On Press - How Do Show That The View Is Being Pressed
Jan 5, 2010I 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.

Android :: Android View Or SurfaceView?
Jul 30, 2010Ive been trying to make a scrollable/zoomable app and everything has gone great except for drawing bitmaps. It is a very large image (6656 by 4096) that i have split into tiles. There is a rectangle array that the bitmaps are drawn to, and it detects what rectangle is in the top left corner so it can draw the bitmaps that will cover the user's viewable screen. My problem is this all lags when the app has to load the bitmaps into memory; Once they are loaded it isnt an issue. I started with 512 by 512 tiles, then went down to 128 by 128. although it helped, there still is some noticeable lag. I have been looking into surfaceView and wanted your opinions if i should stick with View, or use surfaceView to solve my lag.

I then animate the alpha of the currentColorView to zero. At the end of the animation I swap the positions of the views and repeat the process.
View 3 Replies View RelatedAndroid :: Resetting The Background Color Of View
Sep 8, 2010I'm trying to restore the background Color of a View. I have several selectable Views. When the user clicks one of those Views, the following code is executed and the View becomes Yellow:
View newSelection, previousSelection;
...
if(previousSelection != null) {
previousSelection.setBackgroundColor(Color.BLACK); // problem here
}
newSelection.setBackgroundColor(Color.YELLOW);
However, I want to reset the color of the previously selected View. However, I do not know which color it was (I'm setting it to Color.BLACK in the above code). I was not able to find a getBackgroundColor or similar method in the View class. If I had it, I could save the previous color and just put it back when the new View is selected.
