Title Body

In my main layout file, I have a RelativeLayout, with a weight of 1 (basically to display a map) above a LinearLayout with a weight of 2, declared this way : <LinearLayout android:id="@+id/GlobalLayout" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <RelativeLayout android:id="@+id/UpLayout" android:layout_width="match_parent" android:layout_height="0px" android:layout_weight="1" > </RelativeLayout> <LinearLayout android:id="@+id/DownLayout" android:layout_width="match_parent" android:layout_height="0px" android:layout_weight="2" android:orientation="vertical" > </LinearLayout> </LinearLayout> DownLayout contains a list of items, when I click on an item, I would like to change the weight of DownLayout for 4, so the upper layout (the map) takes only 1/5 of the screen instead of 1/3. I have managed to do it by changing the LayoutParams : LinearLayout linearLayout = (LinearLayout) mActivity.findViewById(R.id.DownLayout); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT); params.weight = 4.0f; linearLayout.setLayoutParams(params); It works but I'm not satisfied, the change is too immediate, there is no transition while I would like it to be smooth. Is there a way to use animation for that ? I found some examples with ObjectAnimator to change the weightSum, but it does not do want I want (if I change only this property, I have some free space below my down layout) : float ws = mLinearLayout.getWeightSum(); ObjectAnimator anim = ObjectAnimator.ofFloat(mLinearLayout, "weightSum", ws, 5.0f); anim.setDuration(3000); anim.addUpdateListener(this);
