I need to do a Sliding Up View wich should slide up from the bottom of the screen when I click a button. It has to show on the bottom of the screen and I need to slide/drag it to the center of the screen. The images below explain it better.
almost like the AndroidSlidingUpPanel from "umano" which you can find here:
The problem is that I want the first child (The content of my View - an image for example) to fill all the screen and also I want the second child(the actual bottom bar) to be showed when I click a button. The images below explain it better. If there is not possible to do this by changing the AndroidSlidingUpPanel, how can I do that? I have never worked with views like this. I would really appreciate any tip or help. Thank you very much.
To hide or show panel, you can use
showPanel()
method.
To hide it try this:
SlidingUpPanelLayout slidingPanel = (SlidingUpPanelLayout) findViewById(R.id.sliding_panel);
slidingPanel.hidePanel();
To make it appe
SlidingUpPanelLayout slidingPanel = (SlidingUpPanelLayout) findViewById(R.id.sliding_panel);
slidingPanel.showPanel();
This is available only in v 2.0 of AndroidSlidingUpPanel (https://github.com/umano/AndroidSlidingUpPanel). As I know, it's included in android support library v13 now, but not sure if there is latest version.
You can check this library for dragging content from all four edges of the screen https://github.com/SimonVT/android-menudrawer
You can make a custom layout inside this menu drawer to get your expected result.
You can do it with AndroidSlidingUpPanel, just set visibility:
android:visibility="GONE"
on the 2° child of the view (the panel) and use .showPane() and .hidePane() on SlidingUpPanelLayout to show/hide the panel when you click the button.
The following library do it as well
https://github.com/Paroca72/sc-widgets
Inside you will find a widget named ScSlidingPanel.
This widget work different from the other and can be use and customize very easily.
You put it inside a RelativeLayout give an alignment and it will open from that side.. Left, Right, Top and Bottom or mixed..
In your specific case your must align your panel at bottom of the container and it will sliding from the bottom.
<!-- Define the container -->
<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"
tools:context=".MainActivity">
<!-- Sliding from top -->
<scapps.com.library.ScSlidingPanel
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<!-- HERE THE YOUR CONTENT -->
<!-- or you can load by setLayout method -->
</scapps.com.library.ScSlidingPanel>
</RelativeLayout>
Another important property that you can use right for your case is the handle size.
You can define an handle and define the beavior of it.. as your image above you used a button.. you can unsing an image and setting setToggleOnTouch() to true for open/close the panel touching on handle.

I'm brand new to android development and I'm using both design view and text view to create a layout.
I've just used a scrollView element on the screen and have started to fill in all of the content. Unfortunately, the content is going off of the page (obviously will be scrollable when it's built). But I would like to be able to see the designed content before I run a build to see it.
Is there any way to expand my view of the scrollView element so I can see the content below the screen?
If you put all of the content you want in a separate layout using merge tag as the top level element you should be able to preview that layout in the preview window. Then just use an include tag to put it into the scrollView
eg
<merge xmlns:android="http://schemas.android.com/apk/res/android">
Your content here
</merge>
And
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/yourlayout"/>
</ScrollView>
See http://developer.android.com/training/improving-layouts/reusing-layouts.html
Well, obviously you can't scroll the screen in Android Studio, but you can set the visibility of any parent view to gone to see how your off-screen views look like, then change it back by removing the visibility attribute in xml.
You can also copy the views that are off-screen and paste them in another new layout for testing purposes only to see how it looks like.
Generally, you can just run the emulater in Android Studio and see how your design looks like too.
I am trying to figure out how to make a swipe view without a tab layout.
In the figure above,
1. I want to make a swipe view that can navigate page left and right.
2. Icon 1 is a global menu that needed to be there all the time while swipping.
3. Icon 3 is a bottom bar. How can I make like that way?
Any kind of suggestions and tutorial links would be appreciated. Thanks in advance.
i don't have any links for the same,but still i will tell you the very simple logic to create:
1.First remove the title bar using
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
2.Use the following Structure
<RelativeLayout>
<ViewPager android:layout_height="fill_parent"
android:layout_width="fill_parent"> //full screen
<RelativeLayout android:id="#+id/header"> -->for header
android:layout_alignParentTop="true"
</RelativeLayout>
<RelativeLayout> -->for inicators
android:below="#+id/header"
</RelativeLayout>
<RelativeLayout> --> for footer
android:layout_alignParentBottom="true"
</RelativeLayout>
</ViewPager>
</RelativeLayout>
3.now make the images for header and footer and set as background.
4.for view pager indicator go Through This Post.just download it and import in your eclipse and set as a lib in your project. how to use circle pager indicator Check My Answer.
and you are done now!!
You can simply use for example a ViewPager as explained in the official documentation because it's not mandatory to have tabs.
http://developer.android.com/training/animation/screen-slide.html
There's a full example available in that link.
If you need also to display dots for your slides, you can take advantage of this library as pointed out by other users: http://viewpagerindicator.com/
Check this library I think this is what you need
and you can customize it as per your needs

I have created custom tab bars by following the post given below:
How to create a Tab-like UI in Android?
No I need to display a set on sub menu when the center tab (actually it is a button) is clicked. I need the sub menu to pop up like in this drawing (sub menu should be above my main layout):
I believe that this can be achieved by putting an additional layout above the custom tab bar in which a set of buttons can be placed one after another. But I am not sure which layout needs to be used and how I can get the same style in the drawing. Please help me to find a solution.
you're correct with just adding another layout above the button you want to open it, and then setting its visibility to gone until you want to animate in it.
a regular LinearLayout would work fine, and then adding 4 buttons to it would work as well, then you would want to make sure those buttons used the same styles as the built-in android menu buttons (or style it yourself) but check out some of the built in styles here
example:
your activity
<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">
//all your other activity layout stuff goes here
<!--add your new menu-->
<LinearLayout
android:id="#+id/my_menu_layout"
android:visibility="gone"
... />
<Button
android:id="#+id/menu_btn_1"
style="#android:style/Widget.Holo.ActionButton.TextButton" //as example of built-in style
... />
//more buttons
</LinearLayout>
then in your activity class, assign an onClickListener to the button that will toggle the menu and animate the view in
//animation xml you make
Animation inFromBottom = AnimationUtils.loadAnimation(this, R.anim.layout_in_bottom);
mMenuLayout.startAnimation(inFromBottom);
mMenuLayout.setVisibility(View.VISIBLE);
now your view will animate in and you can go about adding onClick listeners to the buttons
As I am actually not very confident with programatically changing Views, I have following problem:
At the first start of my app, I want to have an overlay for the main screen, that tells the user to have a look at the settings, as there are two critical options the user has to configure.
I don't want to use an AlertDialog and rather not use a wizard. So, I decided to take an approach similar to Go SMS and create an overlay at the first start. The mockup I created looks like this:
Normal menu:
First start:
So these are the problems I have:
Like I said, I don't want to use a screenshot overlaying on first start, as this would take too much space and would not be language and screen independent.
I would have the circle as an png, but I don't know how exactly put it over the image
The same problem with the text
And finally I want to put a semi-transparent white over the app. It does not necessarily need the hole for the icon, though it would be nice.
In case you need the Layout Source, you can get it at pastebin
So, I just need to get a start here, if it is better to use LayoutInflater or ViewStub and how to realize it, as I have absolutely no experience with it...
Thanks!
/edit: I uploaded a new, more well-arranged layout.
I have faced a similar problem, I client wanted a walkthrough of the application, where the entire screen had to become whiter (as they said: "transparent"), except for the button being explained by an overlay speech-bubble.
Fortunately for you, your layout is not nearly as complicated as the one I had to work with :)
Now, you can get the transparency-effect in two ways, either have a white background and call all the views setAlpha() methods, or you can create a half-transparent white overlay.
If you go with the overlay, you'll have to find a way to display the opaque buttons through the overlay. This can get a bit complicated.
If you go with the first option, you can just setAlpha(1) on the opaque view to get it to show up.
The setAlpha() method is only available from api version 11+, so if you target an earlier version, you might have to do it in a slightly more complicated way.
Example of setting alpha on views pre-honeycomb:
Layout for your buttons (make them however you want, just make them similar so you can loop through them):
<LinearLayout
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:tag="image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/tile"/>
<TextView
android:tag="text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FF000000"
android:text="button1"/>
</LinearLayout>
In your program, when you are want to make the buttons transparent:
LinearLayout l = (LinearLayout) findViewById(R.id.button1);
((ImageView)l.findViewWithTag("image")).setAlpha(0x7F);
((TextView)l.findViewWithTag("text")).setTextColor(0x7F000000);
When you have decided on how you want to create the transparency effect, you will have to decide on how to display the overlay-text/bubble. You'll most likely want to put this in a separate layer on top of your entire layout, to make sure that it is not affected by your new view.
One way to achieve this is by changing your root layout element to a FrameLayout, and then creating/displaying in this. e.g:
<FrameLayout background="#FFFF"> <!-- white background, just in case -->
<LinearLayout>
<!-- the rest of your layout -->
</LinearLayout>
<LinearLayout visibility="gone"> <!-- this will be your overlay view -->
<ImageView /> <!-- the arrow/ring -->
<TextView /> <!-- the description -->
</LinearLayout>
</FrameLayout>
When the introduction is displayed, you set the position of the hidden overlay-view to the position of the table item to be explained, change the text to an appropriate string/resource and display the view.
When the introduction is over, you reset the alpha values of all buttons, and set the visibility of the overlay to gone again.
Since I don't have much experience with ViewStub, I would do it with LayoutInflater.
First of all, you need to have a second layout loaded on top of your current layout. The easiest is to have a FrameLayout, which has as one child your current view, and the dynamically you load the second child on the first start. When you load a content view in an Activity, it will be attached to some already created views (some DecorView, a FrameLayout, etc). So you can either re-use the existing FrameLayout, or you can create a new one.
I would vote for the second solution, since it's more stable (I just mentioned the other possibility in case you want to minimize the number of layers).
So, as a first step, wrap your current layout inside a FrameLayout, and give it an id, let's say "#id/root".
Then, in the onCreate method, you can have something like this:
setContentView(R.layout.main);
if (isFirstRun()) {
ViewGroup parent = (ViewGroup)findViewById(R.id.root); // locate the FrameLayout
LayoutInflater li = LayoutInflater.from(this); // get an instance of LayoutInflater
li.inflate(R.layout.overlay, parent);
}
So far you will have the overlay loaded. Now it's up to you to define the overlay.
To make the whitening effect, just set the following attribute on the root view in your overlay.xml layout:
android:background="#40ffffff"
To position the circle, first you need to find it's location. You can use the View.getLocationOnScreen to get the absolute coordinate of the icon (below the circle) on the screen. Then you can have two options:
either create a custom view (for the overlay) and manually draw the circle at the given location
or add the circle using an ImageView and adjust the left and top margins based on the coordinates
I'm using Eclipse Helios 3.6.2 for Android development and whenever I design a layout in the graphical layout mode (not the XML layout), I can't see the entire content of a ScrollView in the graphical layout.
Specifically, when I'm using a ScrollView and the height of the ScrollView exceeds the height of the content view area (i.e., the phone screen visible in the graphical layout mode), I am not able to see the items that I have at the bottom of the screen.
In Eclipse Helios 3.6.1 there was an option called "expand to fit"; whenever I used to click on it, the phone screen increased in size to encompass all the elements that I had added. How do i achieve the same thing in 3.6.2?
There's no way to scroll the content inside the Android Layout Editor. What you can do, though, is create a new device simulation with a huge height, so you can see what is hidden in the ScrollView.
To do so, go to the dropdown menu below "Editing config" ang choose "Custom..." (top-left corner of the Android Layout Editor). Select one of your preferred resolutions (mine is 3.7in WVGA) and hit "Copy". The copied resolution will appear in the "Custom" group in the bottom of the list.
Choose your new configuration and hit "Edit...". In there, you can select the "Screen Dimension" property and change the value. I created a resolution 2000x480 (portrait). This way, I can see the whole content inside the ScrollView.
Hope it helps.
Use an included layout for the scrollview.
Move the entire scrollview layout in a separated file (ie: my_scrollview.xml).
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
...
</ScrollView>
The layout editor will then display the entire scrollview.
In the main layout use in place of the scrollview something like:
<include layout="#layout/my_scrollview" />
There was a button that allow to remove the clipping generated in a scroll view and show all the views that you have inside it.
In later sdk versions the button is removed, and the view mode is triggered if the scroll view is the root element of the view, so my solution when this doesn't happen (because you have a relative layout with some buttons over the view for example) is extracting the scrollview to it's own view, and including it in the original layout with an include tag.
My quick fix.
In the upper right corner of the graphic layout window you will see a drop down menu that shows what minimum version of android you are creating for. Make sure you have it set to at least android 2.1. I had an app at 1.6 and i had the same issue you have. swapped minimum build platform to 2.1 and it was magic.
Hope this helps.
If use Relative layout, you can use layout_marginTop negative, like that:
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="-500px"
android:layout_alignParentLeft="true"
android:layout_below="#+id/linearLayout" >
Increase the layout_marginTop to move scrollview.
The drop-down on the left (under the text "Editing config: ...") allows you to change the simulated screen size in the graphical layout. Perhaps that is what you are looking for.
Just click on the Config window of the Graphical Layout and click on the preview for all screen sizes and u will be able to see your scroll
Use the android:scrollY in the ScrollView child and remove it before publishing.
<ScrollView ... >
<LinearLayout ...
scrollY="300dp">
</LinearLayout>
</ScrollView>
