This Activity Code move Like a Iphone Horizontal Scroll.
second Code is ScrollView Library.
The Better Idea If you have, Comment Please.
Or Critics Welcome.
public class HorizontalScrollActivity extends Activity {
private StickyHorizontalScrollView scrollView;
private ArrayList<View> viewList = new ArrayList<View>();
private ViewGroup mLayout;
private ViewGroup mLayout2;
private ViewGroup mLayout3;
private LinearLayout mLayoutContainer;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
scrollView = new StickyHorizontalScrollView(this);
scrollView.setHorizontalScrollBarEnabled(false);
scrollView.setFadingEdgeLength(0);
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
DisplayMetrics mDisplayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(mDisplayMetrics);
int deviceWidth = mDisplayMetrics.widthPixels;
int deviceHeight = mDisplayMetrics.heightPixels;
mLayout = (ViewGroup)inflater.inflate(R.layout.main, null);
mLayout.setLayoutParams(new LayoutParams(deviceWidth, deviceHeight));
mLayout2 = (ViewGroup)inflater.inflate(R.layout.main2, null);
mLayout2.setLayoutParams(new LayoutParams(deviceWidth, deviceHeight));
mLayout3 = (ViewGroup)inflater.inflate(R.layout.main3, null);
mLayoutContainer = (LinearLayout)mLayout3.findViewById(R.id.bodyLayout);
mLayout3.removeView(mLayoutContainer);
viewList.add(mLayout);
viewList.add(mLayout2);
int i = 0;
for(View v : viewList){
mLayoutContainer.addView(v);
scrollView.addStickyPosition(i++ * deviceWidth);
}
scrollView.addView(mLayoutContainer);
setContentView(scrollView);
}
}
And This Code for Iphonish HorizontalScrollView Library.
public class StickyHorizontalScrollView extends HorizontalScrollView {
protected ArrayList<Integer> stickyPositions = new ArrayList<Integer>();
private boolean flinged = false;
private final String TAG = "StickyHorizontalScrollView ==========";
public StickyHorizontalScrollView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
@Override
public void fling(int velocityX) {
// TODO Auto-generated method stub
Log.d(TAG, "FLING");
flinged = true;
int lastSmaller = 0;
for(int sticky : stickyPositions){
if(velocityX > 0 && sticky > getScrollX()){
smoothScrollTo(sticky, getScrollY());
break;
}else if(velocityX < 0){
if(sticky > getScrollX()){
smoothScrollTo(lastSmaller, getScrollY());
break;
}else{
lastSmaller = sticky;
}
}
}
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
// TODO Auto-generated method stub
Log.d(TAG, "TOUCH");
flinged = false;
boolean res = super.onTouchEvent(ev);
if(ev.getAction() == MotionEvent.ACTION_UP && !flinged){
sanitizeScrollPosition();
}
return res;
}
public void sanitizeScrollPosition(){
Log.d(TAG, "SANITIZE");
Integer minDistance = 0;
Integer minStickyPosition = 0;
for(int sticky : stickyPositions){
int distance = Math.abs(getScrollX() - sticky);
if(minDistance == null || minDistance > distance){
minStickyPosition = sticky;
minDistance = distance;
}
}
smoothScrollTo(minStickyPosition, getScrollY());
}
public void addStickyPosition(int x){
Log.d(TAG, "ADD STICKY POSITION");
stickyPositions.add(x);
Collections.sort(stickyPositions);
}
public void clearStickyPositions(){
Log.d(TAG, "CLEAR STICKY POSITION");
stickyPositions.clear();
}
}
