i'm in final stage of writing my custom widget (quite similar to Home's sliding panel). it works quite well except one thing: i have some problems with positioning it in FrameLayout (see 3 rightPanel* Panels in main.xml in attached eclipse project).basically i don't like the idea i'm using there: setting layout_marginTop in panelHandle children.

I'm developing an android app and need to know how to change the positioning of a progress dialog. I need it to be positioned at the bottom of the screen instead of at the center like it is by default.
View 2 Replies View RelatedI have the following structure defined in an xml layout file.
<RelativeLayout android:id="@+id/mainLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content">
<FrameLayout android:id="@+id/frame" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" ></FrameLayout>
<Button android:id="@+id/button" android:layout_below="@id/frame" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</RelativeLayout>
The FrameLayout is positioned correctly in the center of its parent. But the Button isn't getting positioned under it. Instead it's displaying in the top left corner. Am I doing something incorrectly or is this a bug with RelativeLayout?
I'm trying to write an app for my Samsung Vibrant (running android 2.1).I used the example "Form Stuff" app available as tutorial on the android developers website. I basically added a background picture to the application. the background picture has some text on it towards the top. I want to display a list of elements (to be selectable by teh user) but I want this list to start from a certain position on the screen (say for example - start from the middle of the screen). tried reading the listview under dev resource and searched the forums but I could not find a way to do this.Could anyone please help me out? or if this is not possible, then suggest me something else which i can place at a certain position on the screen.

I have two SurfaceViews in one FrameLayout. So they are stacked upon another. What I want to achieve is to use the lower SurfaceView as kind of background that is changing heavily, and the upper SurfaceView as annotation overlay. So the upper SurfaceView has a (small) number of quickly changing elements that I will draw. Somehow, I can always only see one of the SurfaceViews, depending on which one is top. I thought that SurfaceViews are always transparent, but it seems I am missing something here.Any thoughts on why I can't overlay two SurfaceViews?

How to align the child in right side in FrameLayout ?

View 1 Replies View RelatedI want to add a view inside a FrameLayout programmatically and to place it in a specific point within the layout with a specific width and height. Does FrameLayout support this? If not, should I use an intermediate ViewGroup to achieve this? My initial idea was to add an AbsoluteLayout to the FrameLayout and place the view inside the AbsoluteLayout. Unfortunately I just found out that AbsoluteLayout is deprecated.
View 2 Replies View RelatedI've got a game, a custom View class draws my gameboard. I'm thinking of drawing some elements on a separate layer above the gameboard. I could do this in the View's canvas code, but since they won't change frequently, was thinking of introducing a frame layout to display this top layer.I'm not sure which route to take, the only reason I wouldn't do the FrameLayout is because I'm not sure if it has an impact on battery life. Everytime onDraw() is called, the system probably has to do an alpha composition of the two layers. Is that more battery consuming than drawing the elements from that layer myself in my canvas on every frame? Hard to answer since I'm not sure how complex the drawing will be yet, any general opinions?

View 7 Replies View RelatedIs there a way to get all the children views of a layout, from the Java code so that I can loop through them and set an attribute? Specifically, I'd like to set the "layout_width" based on the screen size. Since this "layout_width" would be the same for all the views, I'd prefer to loop through instead of calling each individual View separately by their id. The following is my main.xml:

I have a FrameLayout in which I have 2 controls:
- a custom view which draws a image and some text on it
- a textview with a text
I want to center both in the FrameLayout but I can't manage to do it. The Texview is centered just fine, my cusom view remains on the left side, when I make it visible.
I am trying to put the zoom controls of the map on the bottom right corner of screen. I could do it with RelativeLayout using both alignParentBottom="true" and alignParentRight="true", but with Framelayout I did not find any such attributes. How do I align it to the bottom-right of screen?
View 1 Replies View RelatedI'm making a image gallery with infinite vertical and horizontal scrolling. I put images inside a ListView to make a column, and put the ListViews inside a TableRow. However, it seems that child views of TableRow is not selectable and as a result I can't select the images in my ListView (easily). Is there a way to pass the events down to child views of TableRow so they can be selectable?

View 1 Replies View RelatedI am trying to create a very simple application (part of my learning program), vertically oriented, with an EditText at the top that receives a URL, and two buttons side by side just below that say "Get Image" or "Get Text" depending on the URL typed in (.html vs. .png, for example). The resulting elements may be later scavanged for use in a real app. I know that ScrollView can have only one child. Conceptually, I want the rest of the screen to be a vertically oriented content region for displaying either the text (TextView) of the URL and "Get Text" was clicked or the image (ImageView) in the case where it was an image and "Get Image" was clicked. I tried to do this (pseudocode) in main.xml:
<LinearLayout> <EditText /> --where to type the URL
<Button /> --click to treat URL as text
<Button /> --click to treat URL as image
<FrameLayout> --(used to be ScrollView) <LinearLayout>
<TextView /> --content region occupied by either text
<ImageView /> --or an image (but not both)
</LinearLayout> </FrameLayout> </LinearLayout>

View 3 Replies View RelatedI'm creating a custom widget that extends AdapterView. Imagine something like a ListView except that the list items can overlap each other with some transparency. Because of the overlap, I'm trying to control the layout and drawing order of the children.
My issue is that the control renders it's children, but ONLY one level deep. Each child is inflated from an XML resource that contains a FrameLayout and an ImageView. The FrameLayout draws, but the ImageView is never visible. I assume I need to call some method to tell the FrameLayout to layout or draw it's children, but I'm not sure what, why, or where. Does anyone know what I'm missing?

View 10 Replies View RelatedI have a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);
Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };
