Android :: How To Show A Webview Inside An Activity In Middle Of Screen
Jul 30, 2010
I am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.
Here is my code.

Can Webview tell me that I didn't get a HTTP 200 OK HTTP response code? I really don't want to display the Android Web Page Not Available screen inside my app.

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.

It seems when screen orientation changes, the activity's onCreate() method is called. In my onCreate() method, I have an AlertDialog which pops up when the activity is called. The problem is when I switch the screen sideways, the popup is displayed again. How can I avoid this?

Has anyone been successful showing a notification, starting an activity, or loading the home screen *during* a call on the Droid? All three of these actions can be done with the emulator running 2.0, but will not run from the Droid. I don't receive any type of notification that these actions fail on the Droid. Although, every action works when a call is *not* active. Missed calls during a call *do* show up in the notification bar, so I am hoping there is a way.
I understand that the notification bar can not be accessed by users during calls, but it would be nice if a notification could at least be delivered. I also understand the security and usability concerns of displaying a window or action during phone calls. Although, there are a lot of users who would like actionable functionality based on calls.

I am using a TabWidget that contains a List in one tab. What I want to do is when a user selects an item, a webview is shown in that tab.
If the user then wants to go back to the list, they would click on the list tab.
I can get the webview up that replaces the whole tabwidget but don't know how to leave the tabs and show a webview.

Currently working on a simple app to allow users to find various things around them. When the activity that shows the Google map is active I can see the GPS icon on the status bar, which is normal. But I need to be able to stop the GPS hardware when my user navigates away from the activity, and switch the GPS back on when the activity is shown.
Is there a simple way to stop GPS when a user navigate away from an activity? I have tried the LocationManager's removeUpdates() but this doesn't actually stop the GPS (the icon is still flashing on the status bar and draining the battery).
What I'm looking for is a simple way to programatically stop the GPS hardware.

After destroying my camera flash with with some app i managed to destroy also my LCD screen. I forgot to take my phone out my back pocket and sat down. Now the phone has a black spot in the middle for the LCD screen.
Do you think I should send it HTC service for warranty and let them replace the screen (guess it will be expensive) or should I replace it by myself?

How can I show pictures in WebView without saving images into file system?
I have tried to implement my custom Content Provider, but method openFile returns ParcelFileDescriptor that points into filesystem (or socket). My pictures are in filesystem, but in encrypted form.
I have tried also URL.setURLStreamHandlerFactory, but in android java it is useless (because custom streamHandler can be register in jvm that is not allowed). I also try html code "img src="data:image.gif;base64,R0lGODlhiAAkAMQAANOOk...", but in embedded chrome it's not working.
