Can anybody tell me how to get the current position of the index while reading the binary file from DataInputStream? I have seen a mark() method but one is Boolean type and the other is void. I need to read the indexes on separate locations to use them again.

I want to insert a constant string into an EditText by the press of a button. The string should be inserted at the current position in the EditText.
If I use EditText.append the text gets inserted at the end of the EditText.
How can I do that? I couldn't find a suitable method.
How do i find the current orientation of the phone (portrait or landscape) How do i find the slider position?

Code:

I'm currently developing an app for Android which uses google map service. Because users will be able to see thousands of markers I would like to load only those which are currently within the map bounds (i.e. when user look at specific map tile). I know how to do it with javascript/html. However, Android doesn't seem to provide any similar methods such as containsLatLng(latlng) or getBounds (I only found getLatitudeSpan and getLongitudeSpan, but don't know how can I use them in order to achieve the similar effect). Can anyone give me some hint on that?
View 4 Replies View RelatedI have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top
View 4 Replies View RelatedIn my actual project I need to draw a MapView with a given running/walking/cycling path on top of it. I don't need the current position so I added an overlay just for the path (no MyLocationOverlay). The path is painted but I don't see the Map in the emulator - only the grey tiles. The apiKey is set in the layout (MapView) and INTERNET permission is set in the Manifest. So I'm wondering if I need more. Is it the emulator simply not working well (I do have 3G and 2 bars in the emulator) or do I need something else? Do I need to build an additional overlay or add additional permissions (xxxLOCATION) to the Manifest.

View 2 Replies View RelatedOn my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.
The default behavior of an activity when BACK softkey is pressed is, GO BACK TO PREVIOUS ACTIVITY. If some the same activity is waiting for some response from server or some data updation is going on and then press BACK, I want to wait on the same screen till the current task is completely processed and then move out to the previous activity.

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!
