describes how to use android.os.Handler to create repeating events. I
used that along with a an OnTouchListener to repeat the button's
action every 100ms until the button is released.
Below is a snippet of code that demonstrates the basic idea. If you
find any flaws with this or come up with a better approach, please let
me know.
public MyActivity extends Activity
{
private Handler mHandler = new Handler();
private Runnable mUpdateTask = new Runnable()
{
public void run()
{
Log.i("repeatBtn", "repeat click");
mHandler.postAtTime(this, SystemClock.uptimeMillis() +
100);
}
};
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button repeatButton = (Button)
findViewById(R.id.repeatButton);
repeatButton.setOnTouchListener(new OnTouchListener()
{
public boolean onTouch(View view, MotionEvent motionevent)
{
int action = motionevent.getAction();
if (action == MotionEvent.ACTION_DOWN)
{
Log.i("repeatBtn", "MotionEvent.ACTION_DOWN");
mHandler.removeCallbacks(mUpdateTask);
mHandler.postAtTime(mUpdateTask,
SystemClock.uptimeMillis() + 100);
}
else if (action == MotionEvent.ACTION_UP)
{
Log.i("repeatBtn", "MotionEvent.ACTION_UP");
mHandler.removeCallbacks(mUpdateTask);
}
return false;
}
});
}
}
