I've just edited my XML, I've put slide menu code in my XML, but there is an error. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ffffff" > <ListView android:id="@+id/menu_content_menulist" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="8dp" android:cacheColorHint="@android:color/transparent" android:divider="@null" android:listSelector="@null"/>

I m making an app and i want to be able to move a view using its margins dynamically. I tried using this : RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)cover.getLayoutParams(); params.leftMargin= 470; params.topMargin= 20; cover.setLayoutParams(params); (cover is an ImageView) The problem with this code its that it uses px instead of dp. I also tried using DisplayMetrics to convert my px values to dp but failed . Can you help me ? You need to set margin according to dpi - DisplayMetrics displayMetrics = new DisplayMetrics(); WindowManager windowManager = (WindowManager)

My question refers directly to this question . The answer to that question shows how one can create a ViewGroup , embed it inside a WindowManager , and allow the WindowManager to catch MotionEvent s through onTouchEvent(MotionEvent event) . WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH is the flag that allows this this ViewGroup to receive MotionEvent s. However, according to documentation, this flag ...will not receive the full down/move/up gesture I want to know if there's a work-around or a way so that I can get all touch events including down, move, and up. A proof of concept is in

I have a textview that I want to change the width to match_parent and height to remain at wrap_content. It is nested within a horizontal linearlayout.
