HTC EVO 4G :: Water Damage Indicator Inside Phone

Jun 11, 2010

Today was the first time I ever took the phone out of its case and removed the back cover, its been in a case 24/7 since I got it. I noticed the water damage indicator is white with a pink "checkerboard-type" pattern throughout it. Does this mean when the BB employee put the Zagg cover on with the water that he turned this pink therefore indicating water damage? If so I am going to be upset and what do I do about it? It's not like I can go back to BB now and claim they damaged it, but how can I prove I didnt expose it to water myself (I didnt, I am exceptionally careful with my phones). My phone works completely fine so no problems now but you never know in the future. Any advice?

Android : Way To Stop GPS Inside An Activity

Aug 12, 2010

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.

I was wondering if there is a way to show a widget that I have created inside an activity. I have a weather widget and I also have an app I am working on that I would like to include weather reports in. Is there a way I can just re-use the widget code and make it show inside the weather activity?

Android :: What Is Best Way To Stop Activity And Alert User?

Sep 2, 2010

I have an application that must create a database and if that fails, then no sense moving forward. I've built an AlertDialog and show() it but it never displays. The logic falls through and then barfs because of the missing database.What is the right/best way to throw up a message and halt the activity? The code below executes fine (meaning the show() occurs while debugging and it falls to the next line) but the UI never displays this alert.BTW I realize the throw might not be the most graceful but I'm not even getting that far so.

Android :: Put Camera Preview Inside A Surfaceview In An Activity Xml Gui

Aug 27, 2009

I just got my camera preview working for my app, but it is not appearing where I want it to appear, and I'm not sure how to get it there. Instead of using the entire screen for the preview, I would like to put it inside a surfaceview in an activity xml gui. What do I need to change? Here is my code:

public class TakePic extends Activity {

SurfaceView camSurface;

Preview camPreview;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_NO_TITLE);//hide window title

camPreview = new Preview(this); //create preview

setContentView(R.layout.takepic);

setContentView(camPreview); //set preview as activity content

camSurface = (SurfaceView) findViewById(R.id.camsurface); }

I would like to access the public method of an Activity run by a TabActivity using: Code...

Basically, what I what is to let the parent Activity call a method in child Activity in order to do something. Is this possible?

I did try this:((TeamHuddleScreenMsgsView)getTabHost().getCurrentTabView().getContext()).refreshModel(); but I'm encountering a ClassCastException. It seems that the getContext() still gives the TabActivity. Any help on how to get the child Activity?

Android : Inside TabActivity / How To Get Instance Of Current Tab Activity?

Apr 23, 2010

I have attached a menu to my TabActivity, and when a menu item is selected, I would like to do something different based on which view is being currently displayed in the TabHost.

int getCurrentTab() returns me the id of the current tab... but from that int how can I get the instance of the activity running?

I also tried getCurrentView(), getCurrentTabView(), but these return things I can't seem to cast to the class of the current activity.

Android :: Method Of Service Does Not Take Place Immediately From Inside Activity

Aug 6, 2010

I have an activity A which uses SharedPreferences to share data with a service S, which is called from within A.Now when I call the stopService() method from A, the onDestroy() method in S is not called immediately.I thought that all the activities and services under a single apk run in just one process. Why then does the jump to onDestroy() not take place immediately instead I can see the output from onDestroy() after the further code in the activity A is executed.

Android :: Accessing Activity Methods Inside Click Listener

Aug 25, 2009

I have a click listener:
private OnClickListener onMyListener = new OnClickListener() {
public void onClick(View v) {
myMethod();
} };

And my Method:
private String myMethod() {
TextView tv = (TextView) findViewById(R.id.TextView1);
return (String) tv.getText();
}

When it calls this method, at tv.getText() it breaks in the debugger.
With this in the stack --

Android :: Cannot Call Method Of View Object Inside Activity

Nov 7, 2010

In my program I have a custom view object. Inside the view class is a method called foo. For some reason when I call foo from my activity, it doesn't fire. Here is the code:

XML of the custom view:
<com.company.application.MyView android:id="@+id/my_view" android:layout_width="wrap_content" android:layout_height="wrap_content" />

The activity code:
public class Main extends Activity { MyView mView;
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = li.inflate(R.layout.main, null); mView= (MyView) v.findViewById(R.id.my_view);
//A button to fire the method inside foo() Button switchLeft = (Button) findViewById(R.id.switch_left); switchLeft.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { callTest(); } } );
} public void callTest() { Log.w(this.getClass().getName(), "clicked left arrow");
mView.foo(); mView.postInvalidate();
} }

Finally here is foo:
public void foo() { mBackground = mContext.getResources().getDrawable(R.drawable.temp_canvas); Log.w(this.getClass().getName(), "background set");
}

The first log is always written when the button is pressed, but the second log is not because foo never fires. What is the deal here? Upon request, the full view

public class MyView extends View { Drawable mBackground; Context mContext;
public MyView (Context context) { super(context); mContext = context;
mBackground = mContext.getResources().getDrawable(R.drawable.leftarrow1);
} public MyView (Context context, AttributeSet attrs) {
super(context, attrs); mContext = context;
mBackground = mContext.getResources().getDrawable(R.drawable.leftarrow1);
} public void foo() { mBackground = mContext.getResources().getDrawable(R.drawable.temp_canvas);
Log.w(this.getClass().getName(), "background set"); }
@Override public void onDraw(Canvas canvas) { Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL); // draw a solid blue circle
paint.setColor(Color.BLUE); canvas.drawCircle(20, 20, 15, paint);
// draw a test background mBackground.setBounds(0, 0, 300, 400);
mBackground.draw(canvas); }
}

Is their a way to workaround this?I am trying to do this via pure code only.

Android :: ScrollView With Buttons Inside / No Response Until Second Click On Any Button Inside

Oct 30, 2010

I've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.

Android :: ListView Inside LinearLayout Inside ScrollView

Jul 7, 2009

So I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?

Android :: Battery Indicator Pro

Aug 24, 2010

I absolutely love this app! They just updated the app so that it will log what's using the battery. The app will now provide you with battery power left depicted in time by usage, for example heavy usage. I'm loving the update. Also, if you have the app log everything that's utilizing the battery, you will see a decrease in battery power. So read the tips/hints the developer included with the update before having the app log everything.

Android :: ExpandableListView Indicator Over My Text

Dec 2, 2009

I'm using an ExpandableListView in one of my activity in a RelativeLayout

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

And I'm using a custom expandableListAdaptaer which group view is:

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

(Found on examples of API_Demos, ExpandableList1)

A user of my application report me this photo http://binomed-android-project.googlecode.com/issues/attachment?aid=-... As you can see, the indicator of group items is over the text of group item despite the padding of 36...

And if I'm running emulator WVGA800 or an emulator with "abstracted LCD density" to 240 I have the same problem, but with my phone (HTC G1), I don't have any problem.

What is strange is that I try the application API_Demo with an emulator WVGA800 or an emulator with "abstracted LCD density" to 240 and I go to ExpandableList1 activity and all is alright !

I also try to copy the inner class available in ExpandableList1 for adapter and I launch it into my activity and I also have the problem see on photo

I am forced to manage density into my adapters in order to adjust the padding?

Android :: ListView Details Indicator

Aug 19, 2009

Anybody knows how to get the ">" sign in the listview? Like for example is done in the gocart app (now shopsavvy), see screenshots here: http://code.google.com/intl/nl/android/adc/adc_gallery/app.html?id=17 The idea of the ">" sign is to show the user there's more information available (when clicking on the entry).

I know how to do it by making my own custom items in a ListView. Is that how they probably did it? Thus with their own drawable on the right? I'm kindof hoping I don't need to do it this way, that there's already something in existence for it :)

Is there a theme or something else that does it for you? Or at least an existing drawable (I did not find it here [url]

i'm trying to use TabHost and TabWidget in my Android application.The problem is that i do not want my tabs to be so tall (65px). However, if i set the layout_height of the TabWidget to e.g. 30px, i can't see the tab labels (indicator) on the tabs at all.Seems like there is a "minimum required" height for the TabWidget (65px?) and the indicator is positioned at the bottom of this 65px?Is there a way to adjust the positioning of the indicator?

Android :: Audio Capture With Signal Level Indicator

I want to capture audio and along with the audio I also want to show the live signal strength of the audio on the screen.

Is there ant api that give me information regarding the the loudness level (or at least some information indicating whether the user is silent or speaking something) of the audio or should I implement my own signal processing using the captured buffers and determine the level.
