Is there any way to set my sliding drawer on top of other elements in my layout? I have an ImageView which is intended for an album art and I would like to have a sliding drawer overlay at the bottom of that ImageView.

I was wandering if there was a easy way to do the following without android layout
place an image central top
place a button center center
place a button left bottom
place a button right bottom
it doesn't sound that difficult no ?
well I can't figure out a way to place the elements as I want using stupid xml layout.
From http://d.android.com/guide/topics/ui/declaring-layout.html, it said "Instantiate layout elements at runtime. Your application can create View and ViewGroup objects (and manipulate their properties) programmatically."
Can you please tell me how/where I can find example for that?
For example, how can I convert the following layout into Java code of my MyWidget. So that when I put "<MyWidget...>" in my layout xml file, it will automatically build a Gallery inside the MyWidget? code...

It seems linear layout stacks with height of it's first element and shrinks second's element height to that. The XML for those is the following:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#FFFFEE"
>
<ImageView
android:id="@+id/thumb"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="@drawable/example"
android:layout_weight="5"
/>
<TextView
android:id="@+id/text"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="2"
android:text="

</LinearLayout>
Has anyone used the sliding drawer widget? I'm trying to get the widget to slide out from top to bottom, but right now it only seems to support bottom to top or right to left. Any suggestions on how to get it to slide out from the top?
View 2 Replies View RelatedI've looked in many places, but I cant find a decent tutorial on how to make a SlidingDrawer for my application.
Say i already have an XML file, and i want to add a sliding drawer to it..i also want to add a textview and listview object, and some buttons in it...how would i go about doing that?
Can anyone explain how to attach a sliding drawer to an activity. I get the xml creation part but what do you need to call to actually attach your xml creation to the activity, or even better to a layout within the activity.

I tried to construct SlidingDrawer widget programmatically, but had no luck. The JavaDoc says the constructor needs "AttributeSet attrs" parameter, which is "a specified set of attributes defined in XML".
I provided my own implementation of AttributeSet interface, with all the attributes mentioned in JavaDoc, but got a weird ClassCastException - it seems that it assumes the attrs parameter is of type TypedArray, which seems to be impossible to use as base class (constructor hidden). Is there a way to construct SlidingDrawer programmatically and what is the correct contract to use it ? It is no way clear from the documentation.
I have a SlidingDrawer that pops up from the bottom of the screen and fills the screen about 80%. Even though the SlidingDrawer view is in focus, it is still possible to click on items, buttons and other elements in the view that is behind the SlidingDrawer. When SlidingDrawer is active/pulled up/in focus, I want to disable the entire view behind it so it will not be able to recieve clicks and touches. Is there a good way to disable an entire view? I have tried setEnable(false) and setClickable(false) but neither of them work.

I'm currently having trouble with a SlidingDrawer. I want it to be closed when the application starts so it doesn't get in the way. However, it is determined that it will be open, despite putting slide.close() in the onCreate() of my activity. It seems to be closed if i use slide.animateClose() instead, but this slows my application down loads.
How do I make it closed by default? code...
What I want to carry out is that the handle of the SlidingDrawer will be dragged by my finger, and when My finger leaves the screen, the handle of the SlidingDrawer will be just stop there and don't slide to top or bottom.
View 6 Replies View RelatedI'm using a slidingDrawer in my application that has its handler placed at the bottom when in portrait mode. When the user switches to landscape mode (widescreen) I would like to have the handler located on the left. When I change the orientation from vertical to horizontal, the handler is placed on the right.
I have defined my layout XML like this:
<SlidingDrawer
android:id="@+id/l_drawer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:handle="@+id/l_handle"
android:content="@+id/l_content"
android:orientation="horizontal"
android:layout_gravity="left>
Anyone have an idea for how to make it slide from left to right ?
I'm trying to change the icon on the handle when i try to open the slidingdrawer.
When I extract the handle from the view and sets the onclicklistener or ontouchlistener it seems to never get trigget.code...
I was hoping this code should log "onClick" message, but it doesn't. Any ideas?
I cant find a way to set the orientation on my SlidingDrawer when i change from landscape mode to portrait mode visa versa. Initially i set the orientation by xml to vertical. I need to change the orientation to horizontal when the phone is in landscape mode, so i get the handle on the left.

View 1 Replies View RelatedIn my application I change layouts very frequently with most of the user interactions. Each time when a new layout is drawn, the applications memory size is increasing. I can see this in DDMS. This is absolutely fine. I have analyzed my application with memory analyze tool and it shows that there around 42 Table layouts at some point of time and this number increase as user does more interactions with the app. Now my question is why doesn't the GC collect the stale layout objects. Does GC collect on UI widgets also??? I feel it does but can any one tell me what may be the reason for GC not collecting my UI elements.
View 4 Replies View RelatedI need to add some parts of my UI programmatically. I'm doing this because I need to set the ids of some elements up in such a way that they can be easily access in a for loop. So far I have this xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/attr_row" android:layout_width="fill_parent"
android:layout_height="wrap_content"> <EditText android:id="@+id/attr_name"
android:hint="Attribute" android:layout_width="0dip" android:layout_weight="2"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<EditText android:id="@+id/attr_val" android:hint="Value"
android:layout_width="0dip" android:layout_weight="3"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<ImageButton android:id="@+id/drop_attr" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:background="@drawable/btn_delete_states"
android:layout_gravity="center_vertical" /> </LinearLayout>
At the moment, I inflate this xml five times like so:
for (int i = 0; i<5; i++) { LinearLayout attrList = (LinearLayout) findViewById (R.id.attr_list);
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.attr_row, null);
LinearLayout extraAttr = (LinearLayout) row.findViewById (R.id.attr_row);
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
attrList.addView(extraAttr, i, params); }
The link below shows two pictures - the layout hierarchy and the result in the emulator. http://picasaweb.google.com/bengoldcross/Android?authkey=Gv1sRgCJ785I...
As can be seen, the xml is inflated five times successfully but only one is actually displayed. Inspecting the hierarchy viewer a bit more explains why. The layout being displayed is at location x=0 y=111 all the others are being rendered at x=320 y=111. It would appear they are being displayed a) off screen and b) on top of each other. So, why are they and how do I stop it from happening?
Here's a quote from Android's Dev Guide: A central feature of Android is that one application can make use of elements of other applications (provided those applications permit it). For example, if your application needs to display a scrolling list of images and another application has developed a suitable scroller and made it available to others, you can call upon that scroller to do the work, rather than develop your own. Isn't it a bad practice to make an app dependent on other apps?
View 2 Replies View RelatedI have a database filled with records in the following format: . What I want my application to do is select records from an external database, and display those records on the phone screen using a SurfaceView.
Currently, I have an Activity, and a Service responsible for the record-gathering portion of the application. The Activity passes an intent to the Service, and the Service responds by returning the records that need to be displayed. The records are stored in my program as instances of the Data class, and merely have the screen-coordinates of where the element should be drawn in the View (I am just drawing a circle for every record in the DB).
For the sake of brevity, I won't include the service but I will include a skeleton of the Activity class and the Data that I wish to display.
CODE:.................
The problem that I am having pertains to the SurfaceView. I realize that many people are going to suggest that I use just a regular View, but my application involves a lot of elements, so a SurfaceView would be much more suitable for my needs. Below is a skeleton of my SurfaceView class that contains a nested class to manage the threads.
CODE:............
The problem that I'm having is that once I make the initial call to the Panel class, I'm going to be getting new records from the service, and consequently, my Info Map data-structure is going to get updated. However, my Panel class just gets stuck in a loop and never receives any new Data objects. All examples of SurfaceViews I've found have involved updating them methods within the SurfaceView class itself (e.g. touching the screen and creating a new image, etc.) Sadly, I'm stumped on this particular problem. Is there a better approach for designing my Activity/SurfaceView interaction? Is an additional View required?
This is probably a very "newbie" question as I'm relatively new to the android sdk, but figured this would be good place to ask.
Say you have a layout with several textviews that all have sequential IDs (ie, tBox1, tBox2, tBox3, etc).Is it possible to reference each box in a loop? Something like:
do { iCount++; View tvBox1 = findViewById(R.id.tBox[iCount]); }
