View 9 Replies View RelatedAndroid :: Create Text View That Flashes When Clicked
Apr 2, 2010How do I set up a TextView to flash when it is clicked? With flashing I mean that I want to change the background color of the TextView. I essentially want one of the objects that is displayed in a ListActivity, but inside a normal View. I have tried to do this by adding an OnClickListener, but what I really need is something like adding an On(Un)SelectListener. Using the onClickListener, I can change the TextView background, but obviously the background stays that color. I thought of using a new Handler().postDelayed(new Runnable(){... }) kind of thing to reset the backround after some small time, but I did not know if this would be overkill for what I'm trying to do.What would you recommend?

Sep 27, 2010I am trying to rotate a canvas with canvas.rotate and move an object on it at the same time. The problem is that with the rotation, the coordinate system of the canvas rotates as well, so I get cases when my object is supposed to be moving along the y axis, but the y axis is rotated on place of the x axis. It is a mess. Is there a way to go around this?

Jan 10, 2010I want to detect when a user taps anywhere in a view in my Android application. My code looks like this:
linearLayout = (LinearLayout) findViewById(R.id.linearLayout); // main layout
// ...
linearLayout.setOnTouchListener(this);
// ...
public boolean onTouch(View v, MotionEvent event) {
Toast.makeText(this, "Touch!", 1000);
if (event.getAction() == MotionEvent.ACTION_DOWN) {

Android :: Any Intent To View User Twitter Feed In Application?
Sep 29, 2010I have a user's twitter handle. Right now I'm opening it through a web page like:
String url = "http://www.twitter.com/" + "example_handle";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
If the user has the Twitter android app installed, is there a different intent I can use which gives the user the option to view that user's twitter feed in the Twitter app, instead of forcing them directly to a browser? I'm not sure if the author's of the Twitter app have exposed any such intent.

View 2 Replies View RelatedAndroid :: Canvas Coordinate System
May 28, 2010I'm trying to find information on how to change the coordinate system for the canvas.I have some vector data I'd like to draw to a canvas using things like circles and lines, but the data's coordinate system doesn't match the canvas coordinate system. Is there a way to map the units I'm using to the screen's units?
I'm drawing to an ImageView which isn't taking up the entire display.If I have to do my own calculations prior to each drawing call, how to I find the width and height of my ImageView?The getWidth() and getHeight() calls I tried seem to be returning the entire canvas size and not the size of the ImageView which isn't helpful.I see some matrix stuff, is that something that will work for me?I tried to use the "public void scale(float sx, float sy)", but that works more like a pixel level zoom rather than a vector scale function by expanding each pixel. This means if the dimensions are increased to fit the screen, the line thickness is also increased.
