"android:scrollbars" are used in XML layout file to declare whether a view having scrollbar. I would like do it programmatic. according to api doc, there seems no direct peer method. Should I have to read a attr xml file? http://developer.android.com/reference/android/view/View.html

My app uses a TabHost containing one tab with a ListView and another tab with a simple form. When the keyboard is slid out in order to write into the form fields, I don't get automagic scroll bars added to the LinearLayout around my form elements.
The resource xml follows.
CODE:................
I have a standard ListView. It's not displaying the scrollbar track thumb though. Is there some special setting you need to set in order to show the scrollbars? My definition looks like this:
CODE:............
The listview has data, and it has enough items to scroll.
I have a Dialog implemented with scrollview and a multiline edittext item in the scrollview. I see that I can use the scrollbar in the edittext as the scrollview will take over it. Can they co-exist and work together?
View 7 Replies View RelatedI am working on adding vertical and horizontal scrollbars in a custom drawn View. I have overridden the compute*ScrollOffset, compute*ScrollRange, etc methods and have enabled the scrollbars by called set*ScrollBarEnabled. However, I do not see the scrollbars in my View, even after a call to scrollBy, which according to the documentation calls awakenScrollbars (I assumed awakenScrollbars is not required as the scrollbars do not auto-fade - isScrollbarFadingEnabled returns false).
View 2 Replies View RelatedIn the new official Twitter app, the scrollbars in all the ListViews the app uses are hidden unless the user is scrolling through the list.
When you start scrolling, the scrollbars appear. When you stop, they fade out with an animation until they are gone completely.
I can't seem to find anything in the documentation that indicates this as being a standard feature.
Is this something included in the API? If not, anyone know how this might be done?
How can I take a screenshot programmatically? So far I've learned that:
1) DDMS does it by sending "framebuffer:" to the adb service over a socket, which takes a screenshot in framebuffer_service.c that it sends back.
2) There are some proprietary screenshot apps out there that stipulate the user must have root access, I'm not sure why.
Would it be possible for an Android app to send "framebuffer:" to its own adb service and get the screenshot that way?
Has anyone seen or compiled benchmarks comparing declarative (XML) versus programmatically created UI's in Android? There are things that Google has done to speed up the declarative approach, but you still do have the layout inflation step done at runtime. Have you ever switched (or considered) changing your UI from declarative to programmatic for any reason?
View 1 Replies View RelatedI'm looking for a programmatic way to set-up http proxy settings for android handsets. I've tried using android.provider.Settings.System.putString() to set System.HTTP_PROXY, but my call fails (I'm using a 2.2 emulator image at the moment). My code looks like:
if (System.putString(getContentResolver(), System.HTTP_PROXY, "10.10.2.1:8080")) {
tv.append("put for HTTP_PROXY succeeded. ");
} else { tv.append("put for HTTP_PROXY failed. "); }
I've also added to my android manifest:
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />
Although it's not clear from the docs which permission, if any, is required.
I'm familiar with this SO thread, but the technique there requires manual adb commands, which require the SDK tools and (possibly) a rooted phone. Is there a way to accomplish this? Ideally, I'd like away to set an http proxy that will be used for both data and WiFi connections.
I 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?
Been stuck on this for a while and tried a few various things.Basically I've overridden frame layout to create myself a custom button. The frame layout has two children a button and a linearlayout with items in it.The problem is I'm trying to the get the button to stretch to the size of the frame layout (i.e. fill parent) and it isn't doing.

View 1 Replies View RelatedI wanted to know if it is even possible to either set up or modify email account settings programmatically. I do not believe it is, due to email applications controlling their own settings (and thus would depend upon a ContentProvider from that specific client), but I have not yet found a definitive "no", either.
Further, I was wondering about the email account support on Android in general. It appears that Android 2.0 and above will allow for multiple ActiveSync/Exchange accounts and mulitple IMAP/POP3 accounts, and displays these in the same inbox. Is this claim true? Also, how is this different from the other major Android releases (Android 1.5 and 1.6)?
Is there a programmatic way to read the system logs? i know they are stored in /dev/log.
View 4 Replies View RelatedI am trying to understand the main differences between registering a BroadcastReceiver in the Manifest and registering it programmatically...
My understanding is basically as follows - would appreciate someone correcting my points if I am missing something.
Registered in Manifest:
- The OS will magically find and instantiate your class if needed, calling the onReceive() method, regardless what the running state of your application was
- Your receive will only get called once per broadcast (i.e. You can consider that registering in the manifest is like registering your 'class' for receiving the broadcast - and the broadcast instantiates your class as needed) (??)
Registered Programmatically:
- registering in code means that you are registering instances of your class to receive broadcast messages (i.e. if your code is a little sloppy, and you manage to register several times, you will end up with multiple BroadcastReceiver instances all having their onReceive() called for a broadcast
- to deregister, you need to deregister the specific BroadcastReceiver instance that you previously registered
- if your application gets destroyed by the OS, your onReceive() method will not be called for a broadcast
I would like to implement some sort of remote assistance tool (like vnc) for Android. Is there the possibility to capture a screen programmatically on the device?
View 3 Replies View RelatedIf a RelativeLayout must be generated at run time, what are the equivalent API calls for the attributes set in the XML Layout editor? Take for example this very simple RelativeLayout that places the second ImageView to the right of the first ImageView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="horizontal" android:background="@drawable/ bg_sunrise"
android:layout_gravity="center" android:gravity="center">
<ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/icon"></ ImageView>
<ImageView android:id="@+id/ImageView02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/ ImageView01" android:src="@drawable/icon"></ImageView> </RelativeLayout>
Of the many, variations I tried, I had the most hope for this one, but it didn't work either:
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
RelativeLayout layout = new RelativeLayout(this);
layout.setLayoutParams( new ViewGroup.LayoutParams (
LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT ) );
ImageView imageView1 = new ImageView(this);
imageView1.setImageResource(R.drawable.icon);
imageView1.setAdjustViewBounds(true);
// set the ImageView bounds to match the Drawable's dimensions
RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params1.addRule(RelativeLayout.ALIGN_PARENT_TOP); layout.addView(imageView1, params1);
ImageView imageView2 = new ImageView(this); imageView2.setImageResource(R.drawable.icon);
imageView2.setAdjustViewBounds(true); // set the ImageView bounds to match the Drawable's dimensions
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams
(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params2.addRule(RelativeLayout.RIGHT_OF, imageView1.getId());
layout.addView(imageView2, params2); this.setContentView(layout); }
Can anyone offer the Java equivalent to the above XML? Can anyone explain why there is no attribute, getter/setter, or method for accessing the properties that can be set in XML? What is the most elegant solution for dynamically creating Layouts, Views, and other Resources on the Android platform when there is no Java programmatic equivalent?
Having a problem in Eclipse with regards to an XML file. Eclipse complains that android:scrollbars and android:fadingEdge do not allow Strings. I checked the Android developer site and they do in fact accept strings in the xml file. A related question posed had the problem where there was a missing :android after xmlns. As you can see from the code the line beginning with xmlns is correct I believe. Here is the complete file contents:
<?xml version="1.0" encoding="UTF-8"?>
<com.example.todolist.TodoListItemView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:scrollbars="verticle"
android:textColor="@color/notepad_text"
android:fadingEdge="verticle"
I need to set the TextView maximum height (either using maxHeight or maxLines). And if there are more lines of text the scrollbars should be shown. What markup should I use for this? Initial idea was to wrap TextView with ScrollView, but ScrollView has no maxHeight attribute.

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer.
