• Android Speed based on accelerometer values

  - by fraguas

  Hi. I need to obtain the velocity of an android device, based on the accelerometer values. I made a code that allows me to get the accelerometer values, and then I calculate the velocity, using the formula: v = v0 + at. (vector calculation) My problem is that my velocity only increases and never decreases. I think the problem is that the device never gets an negative acceleration. Can you help me with this?

• Set Round Border of an android TextView already having a background color

  - by vaibhav

  I want a TextView to have a rounded border. This can be done by using a drawable, specifying a shape in the drawable, and then using the drawable as the background of the TextView. android:background="@layout/border" Also shown here However, my TextView already has a background color (which is gray) and thus I'm unable to use the above method to set a rounded border. Is there any other method to do this which allows the background color of the TextView to remain gray and also surrounds it with a rounded border?

  Does Android come with a way to do Full Text Search? I know is it not even possible to search contacts by the notes field, being Google the search company, but I would be disappointed if there is no API for that.

• Android: How can we change the view in the tabs?

  - by achie

  I want to provide a clickthrough on the list in a tab which opens another view. I need to open the new view within the same tab. I then need to provide a back button on the changed layout to change the view to original view. I have tried this. Intent intentA = new Intent(this, AView.class); Now I am trying to access the tabSpec from main activity class[MainTabView] and set the intent as follows. MainTabView.tabSpec1.setContent(intentA); MainTabView.mTabHost.setCurrentTab(0); MainTabView.mTabHost.invalidate(); But this does not change the view immediately but changes it when I go to another tab and come to the starting tab. How can I make it to refresh it as soon as the content has been changed to another intent?

• How to create "floating TextViews" in Android?

  - by Sotapanna

  Hi stackies, I'm programmatically putting various TextViews into a LinearLayout with a horizontal orientation. After 2h of research I couldn't find out how to tell Android not to squeeze all the TextViews in one line but instead to "float" non-fitting TextViews into the next line. I know there isn't something like actual "lines" in a LinearLayout, but how can I tell the TextViews to actually behave like floating DIVs from the HTML world? Thanks alot! Be well S.

• Android "hello world" - versions

  - by Ianb

  Starter question: My "Hello World" attempt won't run, ("No compatible targets were found"), I think this is bacause I selected the latest version for my project (2.2), and the highest AVD version is 2.0.1. Does this make sense? Can I change my project version (haven't been able to find a way to do this), or do I have to start again? If the versions are not backwards compatible, what is the best version to use for the majority of Android devices out there? Thanks
