问题 Somehow I'm not able to fully scroll inside my NestedScrollView. Inside my NestedScrollView is a TextView with a lot of text and a button below it. When I scroll down I can only see a the top part of the button (only a few pixels). It doesn't scroll far enough. This is my layout: <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout

问题 I am using TextSwitcher to put fade in - fade out animation when I set text. But having some problems with wrapping the content by its width when the text is changed. Following is my TextSwitched xml: <TextSwitcher android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:background="#ffffff" android:paddingBottom="1dp" android

问题 I'm trying to use the Android PreferenceScreen as a convenient way to layout my user settings, but I don't want to save the preferences to the device shared preferences. Is this possible, or should I be using a different mechanism such as ListView ? It seems really convenient to use the PreferenceScreen type because I require different widgets (ie. switches, edit text). But I'm already running into problems with persistence, ie. anything I enter is persisted even across sessions when I don't

问题 I want to make a LinearLayout (to which I'm adding items dynamically) scrollable inside a scrollable RecyclerView . On startup, I can see a little scrollbar initially (indicating it's a scrollable view, fades in seconds). Tried appCompat NestedScrollView as well as enabling nestedScrollingEnabled , with no success. How can I make the LinearLayout scrollable inside the RecyclerView ? <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com

问题 So I have a dialog in which the user inputs data, here it is the user's age. So I would like that when/if the user leaves the edittext blank, the edittext will do the shake animation like that in the api demos. So far I cannot get the dialog from not dismissing when invalid info is inputed. Thanks. mInflater = (LayoutInflater) Information.this.getSystemService(LAYOUT_INFLATER_SERVICE); mLayout = mInflater.inflate(R.layout.agedialog, null); mAgeEditText = (EditText) mLayout.findViewById(R.id
