Android Controller
Jeanne Wang
Objective
Create an intuitive and novel approach to a tablet based multi-touch and sensor-enabled controller for a real-time 3D visualization on a 2D platform. Using camera pose information relative to a 3D model displayed on a screen, we can display virtual camera shots in the 3D model space on the tablet.
Android Basics:
- Sandboxed in a linux environment, each application is actually a user
- Model View Controller setup
- Model - Content providers
- View - XML
- Controller - Activity, or Service
- UI Components
- Buttons
Button button = (Button)findViewById(R.id.button1); button.setOnClickListener(buttonOnClick);
- Sliders
- Sliders
SeekBar seekbar=(SeekBar)findViewById(R.id.seekBar1); seekbar.setOnSeekBarChangeListener(sbar);
- TextView
TextView seekbartxt=(TextView)findViewById(R.id.seekBarText); CharSequence t="slider progress:"+progress; seekbartxt.setText(t);
- Listeners
- OnClickListener
private OnClickListener showCamera = new OnClickListener() { public void onClick(View v) { //do stuff here }
- OnSeekBarChangeListener
private SeekBar.OnSeekBarChangeListener sbar = new SeekBar.OnSeekBarChangeListener() { public void onStopTrackingTouch(SeekBar seekBar) { } public void onStartTrackingTouch(SeekBar seekBar) { } public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { } };

Tips
- Tip: An easy way to add import packages to your project is to press Ctrl-Shift-O (Cmd-Shift-O, on Mac). This is an Eclipse shortcut that identifies missing packages based on your code and adds them for you.
- To get cpuinfo on a particular machine look in: /proc/cpuinfo
- To get ipaddress on a particular machine call /sbin/ifconfig
