Android :: WebView Content To Fit Display Screen

Oct 5, 2010

I tried WebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); but view crashed in 1.6 OS. I calculate scale(webview.capturePicture()) but I cannot set it after page loaded. Is it any working solution for fitting webview content to display (1.6 OS)?

Android : WebView - Not Able To Go Back To My Activity Screen Once The Content Is Displayed

Apr 9, 2009

Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application.

Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page.

After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application).

Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case.

Android :: Unable To Add Subview To Linear Layout With Wrap Content

Aug 29, 2010

I'm using data to build elements of a ViewGroup. The ViewGroup are LinearLayouts, except the leaves, which are TextViews. Because Data draws the hierarchy, I inflate the LinearLayouts and TextViews from individual XML files programatically on the fly.

My Problem:
When I create a LinearLayout with the attribute wrap_content, then inflate a TextView or other LinearLayout into it, I can't get the parents (or enough of them, anyway) to redraw, respecting the new view. These LinearLayouts always seem to come out at 0 size, because when they are first created (before their children are inflated), they wrap around nothing. I've tried calling some stock methods of ViewGroup but nothing seems to work.

Android :: Can Prevent Words From Breaking In Textview When Using Wrap Content In Android

Sep 20, 2010

I am in the process of trying to convert a desktop app to Android - and am struggling with some very basic stuff. When I specify a layout including a textview that holds a sizable amount of text wrap_content seems to arbitrarily break in the middle of a word - and I can not find any documentation indicating this can be controlled.

Android :: Android - ListView Items Not Grow To Wrap Their Content

Nov 2, 2009

I have a rather complex ListView, with variable list item heights. Under certain conditions, I need to display an additional view in a list item, which is hidden by default (View.GONE). By enabling it (View.VISIBLE), the list item grows in height (or at least it's supposed to).

The problem:
Even though I declare the item's root layout to wrap_content, and each component in the item to fill_parent, the view I hide/show which is supposed to change the item's height is simply cut off at the bottom instead of its parent (the item layout) growing in height to fully display it.

Are there any gotchas related to ListViews and item layouts and item height which I may have missed?

Some more observations:

For testing purposes I have now reduced the list item layout to just contain the root LinearLayout and an ImageView. When I set the LinearLayout height to e.g. 200dip and the ImageView to fill_parent, I would have expected the ImageView to grow until it hits the 200dip limit set by its parent.

However, the image will instead be only ever as tall as its bitmap resource (as if I had set it to wrap_content) and the whole list item will be of the same height (i.e. as if I had set it to wrap_content, too).

If however I set the image height to e.g. 200dip, then the list item will grow in height, and so will the item layout.

In other words, the layout_height of the list item layout is completely ignored, and so is any height value on ImageView other than a hard-coded pixel value.

Android :: How To Mix External / Local Content In WebView?

Oct 12, 2009

I am trying to create a hybrid Android app which pulls HTML content from a web server and renders it in a WebView. However, I also want the external HTML to be able to reference images that are packaged within the android app. I realize that currently it is not possible to do something like <img src="file:///my_image.jpg" /> in the HTML. I have seen discussions of using the ContentProvider to create name spaces in the html, however all of these examples seem to assume that the actual html page is also on the device and tend to use WebView.loadData(). So, is there someway that it is possible to do this? The main goal is to package all the application images/css in the android app, but put the bulk of the application on an external server that returns the actual markup.

Android :: Any Listener For When WebView Displays Content?

Oct 31, 2010

Using WebViewClient and/or the WebChromeClient you can get a listener for when the page has loaded, however this is sometimes called before the WebView has any content in it, before it has displayed anything. What would be a efficient method for determining when the WebView has displayed it's content? When I load a page in a WebView, I want to set the scroll to a specific position. It seems that the scroll position cannot be set until the page is loaded and it has an actual content height. So, I have tried two different approaches to determining when the page has finished loading, onPageFinished() from the WebViewClient and also onProgressChanged() from the WebChromeClient.

Both of these tell me when the page has finished loading. However, the problem is that sometimes it is called before the page has been displayed and therefore the page has no height and the scroll call does nothing. I am trying to find a solid way to determine when the page is ready to be scrolled, i.e. when it has its content height. I imagine I could setup a checking loop after it finished loading to keep looking for when the height is available but that seemed like quite the hack. Hoping there is a cleaner way.

Android :: Way To Find Height Of HTML Content Displayed In A Webview?

Apr 8, 2009

My application generates an HTML file which needs to be displayed to the user . For this purpose I'm using the loadData() API provided by Webview. This HTML file is updated every 2 secs & the same is loaded again using loadData() to display the updated values. On reloading the file the Webview starts displaying again from the top of the file causing the user to always scroll down to the location where he previously was. This causes a very bad user experience. To overcome this issue an alternative that I could think of was to split the file to multiple files that can exactly fit in the the screen. For this I need to find the height of the HTML content that can loaded in a web view. From the WebView documentation I found that an API getContentHeight() is provided for this purpose. Although this method returns me 0 on the first attempt. On subsequent attempt it gives me the height of the page that was previously loaded.

Android :: Pause Flash Content In WebView When Activity Isn't Visible?

Aug 7, 2010

I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)

I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.

Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)

Here is a simple test I put together that loads a game on Kongregate which has some background music:

CODE:..............

I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.

I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?

The documentation for the mobile Flash player says:


Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.


This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!

Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

Android :: Content Provider Blank Screen

Sep 16, 2010

My app has one activity and one ContentProvider, the activity is simple in that it's just a splash screen at the moment with no other logic in it (I do intend to have more activities in the app). The ContentProvider uses SQLite as a back end and loads some static data from files on first install, a slow process due to file sizes and database initialization. My problem is that I want the activity to show up as soon as the install starts and maybe display a progress bar or dialog to show the user progress about the install. At the moment I get a blank (white) screen while the ContentProvider is initialising the data which takes quite a long time and I get "Activity idle timeout for history record" warning in LogCat. My splash screen only shows when the Content Provider is done, from the app standpoint this is undesirable behaviour. One potential solutions would be to manually start the provider via an AsyncTask but I have a feeling that this is a bad approach due to the fact that if the activity is interupted and restarted while the install is underway and a new AsyncTast is created through the activity's onCreate() then I'll have worst problems on my hands. Is there a way to start the content provider in the background and display my splash screen activity straight after the app is started? Note that this problem is only an issue on first install.

Android :: Pull Webpage Or Content From Web Into Widget On Home Screen?

I have a php web page that will randomize an image that is 158x154. I was able to get the android application to work, but would also like to get it to work as a widget. How the heck can I get a widget to pull information from the net? I got the widget to work and layout correctly with a black sample image. I have tried to look at the wiki sample, but it is a bit too complicated for my little brain to grasp. The data that gets pulled looks something like:

<html><body bgcolor="#000000">center>
<a href="http://www.website.com" target="_blank">
<img border="0" src="http://www.webiste.com//0.gif"></a>
