Android: Allow scrolling form with adjustPan - android

I'm working on an Android app with a slightly complex layout and I'm having nightmares to make it work the way I want.
My main layout is defined like this:
<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="#000000"
tools:context=".MainLayout" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:scrollbars="none" />
<LinearLayout
android:id="#+id/menudown"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
... buttons ...
</LinearLayout>
</LinearLayout>
<LinearLayout
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerInParent="true" >
... header content ...
</LinearLayout>
</RelativeLayout>
The idea of the layout is having a content frame(content), a footer menu (menudown) and a header (header) hovering over the content, aligned to the top of the screen. - Sorry guys, no image, confidential project.
The content is inflated with other layouts, depending on the section the user is, and some of them are forms to be filled. So, i just used the adjustPan and everything worked fine.
The problem here is: the client asked me to make the content scrollable while there's a soft keyboard showing, so that the user can view whatever he wrote on the other fields.
And it's painful because: the form fits the screen, so using content as a scrollview won't help, unless it gets resized.
And simply changing to adjustResize does not work because: the menudown goes up with the soft keyboard, which should not heappen. Also, the visual effect is terrible.
The app was already made for iPad (by someone else), and what heappens there is: the menudown remains aligned to the bottom of the screen, under the soft keyboard, which pushes only the content view up. Then, the content becomes scrollable, so that the user is able to see it entirely.

I have this same issue too, making keyboard behave the same way as it does on iOS. The best thing I can get from all the other posts is manually detecting the soft keyboard and moving the view up the difference.
This seems to be the best: How to check visibility of software keyboard in Android?

Android fixed background image in scrollview while scrolling

I have a situation where I need a scrollview to have a background image that shouldn't scroll along with it's parent when moving. Before any of you suggest me the links for setting background image and this that, I have already tried and it's not working.
The whole story goes like: I have an activity with fragments which have their own backgrounds with some input fields. When focusing over input fields, keyboard appears and background image squeezes. For that I put an image on background of scrollview that fixed my issue of squeezing background but raised another concern that background Image should stay static while scrolling the parent scrollview.
The second solution any of you may suggest is setting background of my activity rather playing with scrollview. That's right, but for that I had to make a style element with background of theme which appears odd while transitioning different fragments plus it adds overhead when I have a lot of code and fragments to move forward and back.
That's the point where I am stuck. I have gone through links below, if you just need to know that I tried it or not.
link1
link2
link3
... and so on
below is the layout I am using for my fragments (it's all being done programmatically)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/top_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="none" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/backgroundView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/app_name"
android:scaleType="fitXY" />
<LinearLayout
android:id="#+id/parent_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
</ScrollView>
</LinearLayout>
So if you guys have any better solution keeping in mind the situation I have, will be warmly welcomed. Thank you
None of the above works for me with some reason but this things works.
getWindow().setBackgroundDrawableResource(R.mipmap.img_reg_bg);
put it in oncreate method hope it will help.
If I guess right you try to fix your hotfix to get it working propperly. If I'm right you sould go back to scratch and do it without your scrollview.
If you have a look at following Link:
http://developer.android.com/guide/topics/manifest/activity-element.html#wsoft
you'll see softkeyboard mode can be adjusted. "adjustPan" should solve your problem.
"adjustPan"
The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.
Add someimgage to your drawable folderes, like drawable-mdpi, drawable-hdpi.
In your LinearLayout "#+id/top_layout" add attribute:
android:background="#drawable/someimage"

Android's font doesnt show content in fragment

As we all know, you can customize the font size of your android phone. When a user has the font in large or huge (the common one to use is "normal") and they reach an specific fragment (that has a button), the whole content of the fragment is not shown in screen, the font being so big, moves the text from 2 rows to 4, making it to not fit on screen. I added a scrollview to the fragment to be able to show all the content when the users have this font size selected.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/linearLayoutHeader1"
android:layout_centerHorizontal="true" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical">
---CONTENT----
</LinearLayout>
</ScrollView>
However this isn't showing the whole content (as it is supposed to). The scroll appears and allows you to read whole text,but the button which is under the text is not shown.
try to set
for ScrollView
android:fillViewport="true"
for LinearLayout/your container
android:layout_height="wrap_content"
this is proper way to fill ScrollView without cutting top/bottom edge, maybe this is your problem (description isn't clear at all...)

Status bar always on screen

Good day (or evening, or night)
I'm developing an app for android and I'm very curious about one thing. I have an activity, where user chats with another, like "im" chat. There are an EditText on the bottom and some kind of actionbar on the top. What I need is when user enters a message and the software keyboard is on screen, my activity should move up, but the actionbar should still be "glued" to the top of the screen, because it has some valuable controls on it.
Again, that's not an ActionBar, but just a 48dp height layout in a parent vertical linear layout. So I need to know is there an easy way to prevent it from moving to the top, when the layout moves off the screen.
I tried to put everything in a FrameLayout and put this bar on top of it, but on keyboard opens it goes off the screen too...
On you Activity at AndroidManifest you should put this: android:windowSoftInputMode="adjustResize"
Use something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.myapp.MyActionBar
android:layout_width="match_parent"
android:layout_height="48dp"/>
<LinearLayout
android:id="#+id/mylayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1dp"/>
<!-- Add your edittext and button -->
</LinearLayout>
This will make sure the actionbar and edittext + button are allways on screen, and the mylayout takes up the rest of the screen. When your keyboard is shown, the mylayout will shrink.
Try adding android:windowSoftInputMode="adjustResize" to your activity in the manifest. This tells Android to completely resize your layout when the keyboard comes up, rather than pan it. Note that if there isn't enough room for the entire layout this still won't work. But you ought to be able to make it work if your top level layout is a RelativeLayout, with the edit text set to align bottom, the top bar to align top, and the middle section to fill_parent and be above the edit text and below the bar.
use a RelativeLayout as your base Layout and add android:layout_alignParentTop="true" to your action bar to keep it up
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/action_bar_layout"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignParentTop="true" >
</LinearLayout>
<TextView
android:id="#+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>

How does overlaying views work in Android?

In Android, i noticed that you can have a fixed view on top of another. For example, when you open your browser, and tap the search box, a keyboard prompt pops up (on top of a listview). However, notice that you can still scroll up and down on the listview without the keyboard going away. Like:
would someone please explain (preferrably some sample code in addition) how this works?
What i'm trying to do is just have a custom listview that always has a floating navigation bar on top of the listview and also on the bottom of the list view (it's not actually a header/footer of the listview, it's more like a header/footer of the screen). It would be similar to the example i just described, where the user can interact with both the navigation bar as well as the listview "underneath" the nav bar.
I am somewhat new to Android development, so please be nice and provide a little bit of details if you would :) much thanks in advance!!
whoops. looks like someone had a similar issue:
Layout Layers? Z-Axis?
and this post http://android-developers.blogspot.com/2009/03/android-layout-tricks-3-optimize-by.html explains how FrameLayout works and also how works, which is an even better alternative.
FrameLayout lays object in a different Z-axis, so this is the solution i was looking for.
There are many ways to achieve that, the simpler i can think of is using linear layout :
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/header">
//Here you add whatever you want in your "header"
</LinearLayout>
//create your listview
<ListView
android:id="#+id/content_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:layout_marginRight="10dip"
android:layout_marginLeft="10dip"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip"
android:scrollbars="none"
android:paddingBottom="5dp"
/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/footer">
//Here you add whatever you want in your "footer"
</LinearLayout>

How does Android determine whether to move the layout up when showing the softkeyboard?

How does Android determine whether to move the layout up when showing the softkeyboard?
Note: I am aware that the activity property android:windowSoftInputMode="adjustResize|adjustResize|adjustUnspecified"
exists, as described here http://developer.android.com/guide/topics/manifest/activity-element.html#wsoft
, but in my case it doesn't seem to have any effect. This is my problem:
I have two activities, pretty much the same layout, but the first one is using a ListView that holds a list of buttons. The second activity holds a scrollview with buttons.
The rest is the same, same number of buttons, same height of elements, etc.
Now, when I press the search button to open the search input bar, in my first activity, the entire layouts gets moved up.
While on the second activity, the layout is not being moved up but the softkeyboard just displays on top of it. This is actually how I want it to behave. How can I achieve the same with my activity that's using the ListView?
In my manifest, initially I didn't specify any android:windowSoftInputMode attribute, but even if I do, it doesn't make any difference; I tried all three values (adjustPan, adjustResize, adjustUndefined, without any difference).
This is my layout:
1) http://pastebin.com/5zzVxjbK
2) http://pastebin.com/KFtPuHvP
Interestingly though: when I set my ListView visibility in my layout 1 (left) to View.INVISIBLE, then the layout doesn not get moved up!
I can achieve this with a RelativeLayout and setting android:windowSoftInputMode="adjustPan" like so:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent" >
<include android:id="#+id/Header" layout="#layout/header"
android:layout_width="fill_parent" android:layout_height="wrap_content" />
<ListView android:id="#+id/android:list" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_below="#id/Header"
android:layout_above="#+id/Footer" />
<include android:id="#id/Footer" layout="#layout/footer"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
</RelativeLayout>
You may be able to achive this by setting the footer gravity (or layout_gravity) to "bottom", if you want to keep the LinearLayout, but I am not sure.
