Android new Inbox app style listview with swipe left and right
m trying to build android new inbox style listview with swipe left and right as shown in this image , i have tried 47deg swipelistview but its not that stable , is there any other library available?!
Tried so far with 47 deg
public class MainActivity extends Activity {
Listview pullToRefreshListView;
SwipeListView swipelistview;
ItemAdapter adapter;
List<ItemRow> itemData;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pullToRefreshListView = (ListView) findViewById(R.id.example_swipe_lv_list);
swipelistview = pullToRefreshListView.getRefreshableView();
itemData = new ArrayList<ItemRow>();
adapter = new ItemAdapter(this, R.layout.custom_row, itemData);
swipelistview.setSwipeListViewListener(new BaseSwipeListViewListener() {
@Override
public void onOpened(int position, boolean toRight) {
if (toRight) {
adapter.remove(position);
Toast.makeText(MainActivity.this, "Open to dismiss",
Toast.LENGTH_SHORT).show();
} // swipelistview.dismiss(position);
else {
Toast.makeText(MainActivity.this, "Open to edit",
Toast.LENGTH_SHORT).show();
}
}
@Override
public void onClosed(int position, boolean fromRight) {
}
@Override
public void onListChanged() {
}
@Override
public void onMove(int position, float x) {
}
@Override
public void onStartOpen(int position, int action, boolean right) {
if (right) {
// adapter.onRight();
swipelistview.getChildAt(position).findViewById(R.id.back)
.setBackgroundColor(Color.GREEN);
swipelistview.getChildAt(position)
.findViewById(R.id.imageViewLeft)
.setVisibility(View.VISIBLE);
swipelistview.getChildAt(position)
.findViewById(R.id.imageViewRight)
.setVisibility(View.GONE);
} else {
// adapter.onLeft();
swipelistview.getChildAt(position).findViewById(R.id.back)
.setBackgroundColor(Color.RED);
swipelistview.getChildAt(position)
.findViewById(R.id.imageViewLeft)
.setVisibility(View.GONE);
swipelistview.getChildAt(position)
.findViewById(R.id.imageViewRight)
.setVisibility(View.VISIBLE);
}
}
@Override

Log.d("swipe", String.format("onStartClose %d", position));
}
@Override
public void onClickFrontView(int position) {
Log.d("swipe", String.format("onClickFrontView %d", position));
// swipelistview.openAnimate(position); //when you touch front
// view it will open
}
@Override

// swipelistview.closeAnimate(position);//when you touch back
// view it will close
}
@Override
public void onDismiss(int[] reverseSortedPositions) {
}
});
// These are the swipe listview settings. you can change these
// setting as your requirement
swipelistview.setSwipeMode(SwipeListView.SWIPE_MODE_BOTH); // there are
// five
// swiping
// modes
swipelistview.setSwipeActionRight(SwipeListView.SWIPE_ACTION_REVEAL); // there
// are
// four
// swipe
// actions
swipelistview.setSwipeActionLeft(SwipeListView.SWIPE_ACTION_REVEAL);
swipelistview.setOffsetRight(convertDpToPixel(0f)); // left side
// offset
swipelistview.setOffsetLeft(convertDpToPixel(0f)); // right side
// offset
swipelistview.setAnimationTime(60); // Animation time
swipelistview.setSwipeOpenOnLongPress(false); // enable or disable
// SwipeOpenOnLongPress
swipelistview.setSwipeCloseAllItemsWhenMoveList(true);
swipelistview.setAdapter(adapter);
for (int i = 0; i < 10; i++) {
itemData.add(new ItemRow("Swipe Item" + i, getResources()
.getDrawable(R.drawable.ic_launcher)));
}
adapter.notifyDataSetChanged();
}
public int convertDpToPixel(float dp) {
DisplayMetrics metrics = getResources().getDisplayMetrics();
float px = dp * (metrics.densityDpi / 160f);
return (int) px;
}
}

Answer
Instead of using a custom ListView you can simply support "swipe" gesture on list items onTouch, like the following:
private static final int DEFAULT_THRESHOLD = 128;
row.setOnTouchListener(new View.OnTouchListener() {
int initialX = 0;
final float slop = ViewConfiguration.get(context).getScaledTouchSlop();
public boolean onTouch(final View view, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
initialX = (int) event.getX();
view.setPadding(0, 0, 0, 0);
} else if (event.getAction() == MotionEvent.ACTION_MOVE) {
int currentX = (int) event.getX();
int offset = currentX - initialX;
if (Math.abs(offset) > slop) {
view.setPadding(offset, 0, 0, 0);
if (offset > DEFAULT_THRESHOLD) {
// TODO :: Do Right to Left action! And do nothing on action_up.
} else if (offset < -DEFAULT_THRESHOLD) {
// TODO :: Do Left to Right action! And do nothing on action_up.
}
}
} else if (event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL) {
// Animate back if no action was performed.
ValueAnimator animator = ValueAnimator.ofInt(view.getPaddingLeft(), 0);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
view.setPadding((Integer) valueAnimator.getAnimatedValue(), 0, 0, 0);
}
});
animator.setDuration(150);
animator.start();
}
};
I also use reverse animation if no action was performed.
This solution is lightweight so you should not experience any lags.
