[android-beginners] embeded web browser with custom width and height
I try to create a web browser with custom width and height rather than fill screen, is that possible to do in android? Below is my snippet code: AbsoluteLayout.LayoutParams params = new AbsoluteLayout.LayoutParams( 180, 180, 50, 90); webview = (WebView) findViewById(R.id.webview); webview.setLayoutParams(params); webview.getSettings().setJavaScriptEnabled(true); webview.loadUrl(http://www.google.com;); what am I doing is set web view's width and height to 180 pixels, and coordinate to 50 and 90. when I run this test, it display a white square on screen, nothing render at all. Could any one tell me how to do it in android? -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Does styled text support html tag: p and br ?
Styled text supports: b,i, does it support more html tags, like p or br ? The code below is used for testing styled text: CharSequence str = getText(R.string.styled_text); //retrieve the styled text as char sequence, so it won't lose any formatting TextView tv = (TextView)findViewById(R.id.text); tv.setText(str); I found only the b and i works, other tags just ignore the formatting. -- You received this message because you are subscribed to the Google Groups Android Beginners group.

I figure it out, sometimes the width and height values from
player.getVideoWidth() and player.getVideoHeight() are zero, I do not
know why? ;

[android-beginners] Re: android service repaint
Thanks Mark, this app only has one view, and many custom UI components which is about to draw on screen. A UI component has properties like x,y,width,height and so on. The events and actions that are produced by UI components are placed into event thread. This thread will response to execute each one sequentially, I call postInvalidate() after each execution to update screen, but sometimes I just found postInvalidate() did not paint immediately. I port this app from JavaME to Android, the serviceRepaint() is called after each repaint in JavaME, so it can force any pending repaint requests to be serviced immediately, is there any thing similar for Android or alternative way to do that? On Sep 28, 12:56 pm, Mark Murphy mmur...@commonsware.com wrote: lei wrote: I just found postInvalidate() does not paint the view immediately, is there a method like serviceRepaint() in J2ME ? Nothing paints anything immediately in Android. All GUI events (e.g., setting the text on a TextView) are put on a message queue. Those events are only then processed when you return from whatever callback you are in and let the UI thread go back to processing those events on the queue. If you explain a bit more about what effect you are trying to achieve, we may be able to give you more guidance. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://twitter.com/commonsguy _Beginning Android_ from Apress Now Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.
