May I know is it possible I use the resource id but I didnt set the Content View in the activity?
For example: abc.xml have one TextView id = "R.id.Text". Can I use the use TextView name = (TextView)findViewById(R.id.Text); method in the activity which was setContentView(R.layout.def);?

I've got a tab host activity started from a home screen shortcut. When my application starts it downloads information from a server using an AsyncTask. In the onPostExecute method of the AsyncTask I call setContentView to display the TabHost.When I start the homescreen shortcut by tapping on the shortcut using my finger everything works as expected, I download the information from the server and display the TabHost with the information in the tabs. However starting the application by navigating to the shortcut with the mouse wheel and then clicking on the shortcut with the mouse wheel leads to a trap in the framework code as soon as my application starts. This looks like a simple fix since mCurrentView is null at the time that this method is called - can this issue be addressed? Does anyone know of any workarounds?

View 7 Replies View RelatedI have a WebView inside the ScrollView. The content of WebView dyanamically changes when it displays different html page. I have the following issue: For example I have A.html, and B.html. The content of B.html is larger than A.html, so the page is longer. When WebView load B.html, the ScrollView stretches its size to enable itself scroll for B.html, then if I go back to A.html, ScrollView doesn't resize itself. (The scroll area is exceed the content of A.html) What I want to have, is dynamic change the scroll area of scroll view to fit the webview's content.

View 1 Replies View RelatedI am trying to create a drawable in code and change the color based on some criteria. When I try and set the Drawable as the background of the ImageView it displays but won't let me set any padding. I realized I need to set the ImageView image via the setImageDrawable() function in order to be able to set the padding. The problem I am running into is that when I set it via the setImageDrawable() function nothing is displayed.
Here is what I have written:
<?xml version="1.0" encoding="utf-8"?>
ImageView icon = (ImageView) row.findViewById(R.id.icon);
ShapeDrawable mDrawable; int x = 0; int y = 0;
int width = 50; int height = 50;
float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 };
mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null));
mDrawable.setBounds(x, y+height, x + width, y);
switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break;
case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break;
case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break;
case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break;
} icon.setImageDrawable(mDrawable); icon.setPadding(5, 5, 5, 5);
This results in a space for the ImageView but no image.

I have the following case. I have two string xml files under the dir of res/values and res/values- small. The strings in the two files are used to describe the different activity attribute. But i found that when i run my apk on QVGA emulator, the system always get the string value from res/values.

View 1 Replies View RelatedJust for starters I have not rooted my phone or done anything of that nature. I've only had the phone for about two weeks. I've had an issue with it rebooting on me, though it was due to Locale since the first time it rebooted on me, that was the only thing I had done to the phone. The developer said there was an issue with the api's from samsung.Well since then I havent used Locale, removed it, yet its rebooted just a couple of times(compared to 3 times in an hour when I had locale). Now today, I found my phone completely unresponsive. Black screen, no lights, dead. I pulled the battery, reinserted and tried to power on. It charged overnight so it cant be a dead battery.
When I plugged in, the battery charging logo didnt show up, so I did a reset(vol down+ call+ power), got the behold ii boot logo with Recover text, so I hit the home button. I then got a logo I've never seen. It was a logo of the phone with the warning exclamation point inside a triangle. I left the phone alone for a while but it was still there. I pulled the battery again, reinserted and powered on to a normal boot and the phone came on.I'm going to talk to Tmobile about replacement as this is really weird and I havent seen anyone else say thing like this. And just for info, my battery does have the same serial number that others have found to have an issue with. I'll update with any other info I find out, but I'll probably just get a straight swap without any feedback.
I'm trying to create a listview containing conversations in chat bubbles, and each chat bubbles are rows in the list view. So what I have is an avatar on the left, and a chat bubble on the right. Then in the chat bubble, I have a textview for name, a textview for content, and a textview for time. The problem is, I cannot adjust the height of the chat bubble such that the bottom edge is just below the textview for time. In the chatBubble, I have this line that does not work android:layout_alignBottom="@+id/timeLabel" because timeLabel is a textview created after chatBubble. If I place chatBubble tags right below timeLabel, the height of chatBubble will be just right because lf the layout_alignBottom, but chatBubble covers all the text created before it.
Is there a way I can create the chatBubble last, and bring the view to the background? Or is there a better way to do this?....................

View 4 Replies View RelatedI created an activity by using a layout written in a XML file. I would like, in response to some events, to change the content of this activity. I would like to show a VideoView over the content. In response to some other event, I may want to go back to the first content. Would it be possible to switch the content of the activity this way without running another activity (I have another technical difficult in doing that)? I tried using setContentView( videoView), and then switching back with setContentView(T.layout.main), but it seems that, when going back to the main layout, all my buttons and text boxes are created again as they were new. Would it be possible to go back to the last state of all the controls?
View 4 Replies View RelatedI am getting this exception while I am trying to call an activity from another one.. .The complete exception is android.content.ActivityNotFoundException:Unable to find explicit activity class {com.x.y/com.x.y.class};

Is it possible for me to switch the content's activity programatically after I called 'addTab of TabHost'?
I currently have a tab layout with 2 tabs, one tab with a list view and one with the option make strings so I can add them in the list view. Both tabs have their own activity because this made the code much more structured, and I dont have to repeat my self later.
Lets say im in the tab that offer me to create an string, and i press the update list button, how do I update the list view without startActivity()? If i use startActivity(), it starts List.java, and instead of displaying the list in the list view tab, it takes full screen, which defies the purpose of the tab view. In other words, the startActivity() steals the focus from the tab view of the list, and sends it fulscreen.
I want to update the activity in my list view tab, without starting a new activity that goes to fullscreen, and doesnt update the one in the tab.
I'm trying to query the Contacts content provider outside an Activity. But managedQuery is a method of Activity. Is there any other class/method that I can use instead of managedQuery?
Here's my code:........................
I am writing simple app that will read callLog content provider transform data and write it to my own table. my app will not show data directly from calllog content provider.
1. now one problem that I have is I cannot limit how much rows query will return (by calling activity.managedQuery) but I assume that Cursor delays access to the db and I can use moveToNext as many times as desired to get few rows from table and the call will be efficient. is that good thinking?? OR am I wrong here? I really dont want to query all rows from table. is there any other way to access calllog??
2. I dont want to implement my own content provider for my app. I will use rawQuery many times and group data so contentprovider's callbacks are not enough for me. more I want my dao to be private to my application so I think there is no need to bother with conentprovider. and If I got this right I also dont need to bother with activity.startManagingCursor as long I query data inside same method call (because I need to deactivate all intermediate Cursor objects anyway)
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:
CODE:....................
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.

I am working on developing an app and I am not sure when should I use a new activity and when should I update the existing view.
For example, lets say I have a view that shows a multiple choice question.Now, when the user selects his choices and clicks on say "Evaluate", I want to show the same question view but along with the right answers and explanations for each option. So does that mean, I should send an Intent upon a click on Evaluate or I should just update the view (i am not sure how)?
If I send an intent and show a new screen, how can the user go back to the next question without displaying the answers? If I don't create an new activity, how can I update the existing view that is already displayed?
I currently have a Nexus s, and ever since I upgraded to ICS I am no longer able to view flash content with Opera Mobile. It works fine with the stock browser.
