I need to open a activity at the right part of the screen but still view the old activity at the left part of the screen.
It can be something like a dialog but i need to specify the position of the new activity and also remove the overlay look and feel.
how can i make this?
I have already achieve my first step. putting the activity at a specific position and see the main at the left of screen.
I have used the following style:
<style name="Theme.Transparent" parent="android:Theme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
in my layout file i have setted my linear layout like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="200dp"
android:layout_height="200dp"
android:orientation="vertical"
android:background="#drawable/background_login"
android:layout_gravity="top|right">
this way the activity goes to where i want. now i just need to open the activity with an expand animation and close it with an collapse animation.
Can someone tell me how?
Seems like you're looking for Fragments. Multiple fragments can be shown next to each other, so one fragment can be your left part of the screen and another one be opened on the right side.
Please refer to the Android Dev Guide for more information.

I have a problem with closing my Activity. I'm want to start activity by alarm. I've done that alarm start my activity, but I want to make it a dialog, so I set theme of that activity to android:Theme.Holo.Dialog.NoActionBar but I looks like this:

I've also tried adding:
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">#android:style/Animation.Translucent</item>
<item name="android:windowBackground">#android:color/transparent</item>
But I makes transparent not elements that I want to, it looks like that

Is there way to fix this, or do you have any diferent ideas to make this heppen.
Thanks
I put together a very simple app that uses shared element transitions when starting an activity with Dialog theme (source code on github).
I got the following result:
As you can see there are 2 problems with the transition/animation:
The animation is only visible in the area of the dialog activity so it clips and looks ugly.
There is no transition/animation when I tap outside the activity to
go back.
How can I fix these problems? Any help would be appreciated.
EDIT: After Quanturium's answer I did the following things to get it working:
Use the following theme instead of a Dialog theme:
<style name="AppTheme.Transparent" parent="AppTheme">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">true</item>
</style>
Use a CardView as the background for Dialog look and for rounded corners and shadows.
Call finishAfterTransition(); when user taps outside the CardView.
Now it looks like this (code), the CardView needs refining to better match the Dialog, but it's working at least.:
An activity transition works like this. When you start your second activity, it is displayed on top of your first one with a transparent background. The shared elements are positioned the same way they are on the first activity and then animated to the correct position specified on the second activity.
In your case you are using android:theme="#style/Theme.AppCompat.Dialog" which mean the size of the second activity's drawing area is smaller than the one from the first activity. This explains the clipping and the no transition when clicking outside.
What you want to do is get rid of that theme, and implement your own layout with a dark background / shadow in order to be able to execute your smooth transition.
I currently have an activity that displays a gridView. When a specific button is pressed I create a new fragment that has a transparent content view so that it overlays the activity gridView, so basically you see the content of the new fragment while still vaguely seeing the gridView in die background. The problem I have is that the background view (the gridView) is still active and the user is able to press buttons "through" the fragment view and onto the gridView, if this makes sense. How can I disable the background view/activity (gridView) so the user cannot activate any of the content hosted by it? I was thinking I could do something along the following lines, but it seems very inefficient and hackish:
ViewGroup vg = (ViewGroup) v;
for (int i = 0;i<vg.getChildCount();i++) {
enableViews(vg.getChildAt(i), enabled);
}
Is there any other solution or approach I could take?
I set my transparency for the entire fragments view via style like this:
<style name="Transparent" parent="#android:style/Theme.NoTitleBar">
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:background">#e6000000</item>
</style>
Not sure why this question got down voted as I feel it was a legitimate question, perhaps my phrasing was bad or something. Anyways, I've found a solution incase anyone else ever runs into a similar situation. All you need to do is to set the overlay screens root layout clickable property to true: (in this particular case the fragments main layout)
android:clickable="true"
Currently, I'm using this to show my application background as phone wallpaper.
getWindow().setFlags(WindowManager.LayoutParams.FLAG_SHOW_WALLPAPER,
WindowManager.LayoutParams.FLAG_SHOW_WALLPAPER);
But for some reason when I start my application by pressing the icon. It just shows the activity screen with the icons on the home screen. I didn't use dialog but it looks like a dialog because layout is just set that way. So I just want to show the wallpaper whenever this activity is running. But it only shows the wallpaper only after the next event occurs such as switching to different activity. I already put that code on onCreate() and whenever I do setContentView()..... Is there way to do such thing or there is just no way?
For users of AppCompat, just use the following in your styles.xml, no need for code:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:colorBackgroundCacheHint">#null</item>
<item name="android:windowShowWallpaper">true</item>
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
After long search and trial and error. I've found the solution to what I wanted. It was just creating separate themes.xml file and just tweak the Theme.Dialog which is already defined in default android themes.xml. All I did was change the Animation part. Originally in android themes.xml the line looks like this.
<item name="android:windowAnimationStyle">#android:style/Animation.Dialog</item>
but since modifying in android themes.xml doesn't take the effect. I just created my own themes.xml as I said above and just set parent as android:Theme.Dialog. And added a line like this.
<item name="android:windowAnimationStyle">#android:style/Animation</item>
Thanks for the help and I hope this solution helps others.
Use following code -
rl = (RelativeLayout)findViewById(R.id.someid);
//relative layout is my root node in main.xml (yours may be linearlayout)
WallpaperManager wm = WallpaperManager.getInstance(this);
Drawable d = wm.peekDrawable();
rl.setBackgroundDrawable(d);// You can also use rl.setBackgroundDrawable(getWallpaper);
Can you tell me when we select an item in GalleryView its comes to the center of the screen how to restrict it? I want to just be there where i click that item. How? Simple words, I wanna horizontal Listview. How?
Thanks
HI,
I would advise you check the "Hello, Gallery" on the google doc, it is very clear. Gallery is design to "display items in a horizontally scrolling list that locks the current selection at the center", as they say.
You just need to replace the ImageAdapter by TextAdapter, and put TextViews in it instead of ImageViews. It actually work exactly like a Listview. so you know how to do a Listview, this should be easy.
EDIT
Here is I think a nice solution :
You need to change the style of the gallery. As default it is defined like that :
<style name="Widget.Gallery">
<item name="android:fadingEdge">horizontal</item>
<item name="android:gravity">center_vertical</item>
<item name="android:spacing">-20px</item>
<item name="android:unselectedAlpha">0.85</item>
</style>
So you need to create your own styles.xml in your folder gallery and put that in it :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="gallery" parent="android:Widget.Gallery">
<item name="android:fadingEdge">horizontal</item>
<item name="android:gravity">center_vertical</item>
<item name="android:spacing">0px</item> <!--This gives you no spacing between elements -->
<item name="android:unselectedAlpha">1</item> <!--This puts all elements the same alpha -->
</style>
<resources>
This gives me this :

Now I'm sure we can get better result by playing with the various attributes of the gallery and the style, but I think this is a good lead for you ;)
