I had built an app like ImageSwitcher in the APIDEMO. In the demo, if
you fling the gallery, it will call the onitemselected() function
every image that you fling over. now i want to realize that it will
only call the onitemselected() function at the end of flinging, not
the first and the end image being flinged. i written the code like
this:
public void onCreate(Bundle savedInstanceState) {
Gallery g = (Gallery) findViewById(R.id.gallery);
g.setFadingEdgeLength(100);
g.setAdapter(new ImageAdapter(this));
g.setOnItemSelectedListener(this);
g.setCallbackDuringFling(false);
}
public void onItemSelected(AdapterView parent, View v, final int
position, long id) {
mSwitcher.setImageResource(mImageIds[position]);
}
i use setCallbackDuringFling(false) to controll this, but it failed,
the onitemselected() function still being called more than once. why?
