I want to set up a table layout that scrolls like a spreadsheet. The top row of column headings should scroll horizontally but be pinned when scrolling vertically. The left-most column of row labels should scroll vertically but be pinned when scrolling horizontally. The number of rows and columns is not known in advance. Does anyone know of an example of this? Are there settings in TableLayout that can turn on this scroll behavior? Is there, perhaps, a more advanced widget than TableLayout that can produce this type of scrolling? Are there some tricks I can do with a ScrollView to get this behavior?
View 8 Replies View RelatedI wish to make a scrolling interface. The screen is populated with images in the left one fourth and corresponding text for an image in the remaining three fourth. There will be n number of image-text on the screen and hence should be scrollable. Also image-text when clicked takes you to a new screen. I seem to be stuck and cant think about which layout should I choose. I am a beginner in Android Developing.

I'm having trouble setting up an Android Layout.
What I would like is a scrollable ListView followed by a small bar of text (TextView) that doesn't scroll and always stays at the bottom of the screen.
it would look like this:
ListViewItem1
ListViewItem2
ListViewItem3
Bar of Text Here (always displayed irrespective of scroll state of the ListView)
I've tried a bunch of different variations on this, but none shows the static text

How do you turn on sync in the emulator. I'm already using Google APIs level 8 and I've already created a Google account. But under "Manage Accounts", my Google account says "Sync is OFF".
View 4 Replies View RelatedI've just noticed that launching the Camera and Camcorder (in the emulator) would result in a black screen (instead of the famous moving small boxes), i've looked for why this happening on the net, apparently that the camera is disabled by default when you create an AVD. Decided to create another AVD with the camera enabled and launched it and still getting that black screen. Anyone has any idea how to fix this ?
My problem in the first place is that my application is using the default camera application using intents just like in the following: Intent imageCaptureIntent = new Intent (MediaStore.ACTION_IMAGE_CAPTURE); imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File("/sdcard/imageCaptureIntent.jpg"))); startActivityForResult(imageCaptureIntent, WHATEVER_REQ_CODE); I thought that there's a problem in my intent request but like i said before, running the camera on the emulator itself is the problem. By the way, You can run the "camera preview" in the API demos with no problems, how come!
I am new to Android development and have trouble enabling / disabling the wifi & audio services. I get the appropriate manager instance using the getSystemService method. But I don't get any error when enabling wifi using:
wifiMgr.setWifiEnabled(true);
But the wifi is simply not turned on! Similarly I use
mAudio.setRingerMode(AudioManager.RINGER_MODE_SILENT);
or
mAudio.setRingerMode(AudioManager.RINGER_MODE_NORMAL);.....................

I have written code to enable and disable various things programatically like Wifi, Ringer modes, Airplane modes. All things that you would see in a power toggle widget. The one that I have not found out how to do is bluetooth. It appears that in SDK level 3 (OS 1.5) there is no pretty bluetooth manager class. Has anyone pinpointed any good source examples on enabling and disabling bluetooth that will also be forwards compatible with users running 2.0 (Droid) / 2.1 (Nexus)? I have found a few partial examples in my google searches that I could not get to actually run.
View 1 Replies View RelatedI have used PreferenceActivity to have preference in my android application. I want one preference say "pref 2" to be enabled when other preference say "pref 1" is not checked and "pref 2" to be disabled when "pref 1" is checked. i.e. exactly opposite of the android: dependency attribute. How can I do that?
View 3 Replies View RelatedIn one of my applications I am dynamically enabling the GPS system setting based on a user's request. My problem is that I also have a LocationListener which doesn't pick up this change. If the device is restarted or the system settings Activity is brought up the LocationListener kicks in -- the onProviderEnabled() method is called. So.. it seems pretty obvious that I'm not notifying the system correctly of my changes. I have tried sending a broadcast from both the normal context and the application context. I thought this would be fairly straight forward, but it has proven to be rather frustrating. I put together a small test activity to demonstrate my problem.
Here is my test Activity: package com.example;
import android.app.Activity; import android.content.Context;
import android.content.Intent; import android.location.Location;
import android.location.LocationListener; import android.location.LocationManager;
import android.os.Bundle; import android.provider.Settings; import android.util.Log;
public class TestActivity extends Activity {
LocationListener locListener; LocationManager locManager;
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.test_activity); locListener = new MyLocationListener();
locManager = (LocationManager)getSystemService (Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
if(!locManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
Settings.System.putString(getContentResolver (),
Settings.System.LOCATION_PROVIDERS_ALLOWED, LocationManager.GPS_PROVIDER);
Intent intent = new Intent(Intent.ACTION_PROVIDER_CHANGED);
sendBroadcast(intent); } }
private class MyLocationListener implements LocationListener {
public MyLocationListener() { Log.d("test", "MyLocationListener()");
} public void onLocationChanged(Location loc) {
Log.d("test", loc.getLatitude() + "/" + loc.getLongitude());
} public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub Log.d("test", "*** onProviderDisabled (" + provider + ") ***");
} public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub Log.d("test", "*** onProviderEnabled (" + provider + ") ***");
} public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub Log.d("test", "*** onStatusChanged ***");
Log.d("test", "provider = " + provider + " status = " + status);
} } }
Under the 2.1 SDK, is there a way to test for the phone's OS version within the app, and to enable or disable features based on this OS version? In other words, I'd like to do the moral equivalent of this...
if (os_level < 1.6) {// code goes here}
I have an application that has multiple activities with the intent action.MAIN (category LAUNCHER), so that multiple shortcuts appear in the "Applications" list. Is it possible to disable some of these activities at run-time (so that the corresponding shortcuts disappear from the "Applications" list)?

View 1 Replies View RelatedI have a very hard time with the slide to answer feature. It frequently takes me 3-5 tries to answer a call. I would much rather be able to touch to answer. I do realize that there's a slim chance of answering calls while in my pocket, but I'd rather that then fight with the phone. Does anyone know of an application for this? I've searched various forums and there are no current threads regarding this.
View 8 Replies View RelatedWe would like to enable or disable widgets via code. When we say "disable" we mean that a widget which is registered in an application should not show up in the list of widgets available to the user when they try to add a widget to their home screen. This question has been asked, unfortunately, many times without answer. There was one response by Dianne Hackborn to a separate widget question which suggested that it was possible to use the package manager to disable widgets.

I have an app which displays a large amount of text for the user to read. I've found that when reading while lying down, I get annoyed that the screen rotates even though my head and the screen are aligned. I do not want to set this to be permanently in portrait mode, so I think this would preclude an approach of setting the android:screenOrientation="portrait" in the manifest. Ideally, I would like to enable/disable automatic orientation changes via a preference page.
View 1 Replies View RelatedI asked this a while back and didn't get anything useful. I'm hoping now that Android has advanced a few releases, that there will be more options. Here are the things I'm trying to accomplish: Prompt for a PIN when you uninstall a particular app. This would have been set at install time by the user. Disable certain services (text, phone). What would be even better is if I could be selective about it instead of just turning the radios off. For example:
a. intercept outgoing call, is it to one of a few allowed numbers?, yes
=> allow it, no => deny
b. intercept incoming call, is it from one of a few allowed numbers, yes =>...........................
Seems to me that Lock 2.0 is the best Screen Lock I've found. Only Issue is, even with the security code enabled, all one has to do is power on/off the phone and your in with no need for the code. What I am looking for is a locking app that doesn't get disabled when powering the phone off/on. Looking for something secure much like every BB has where no matter what you do, to proceed into the phone you need to type in the Lock Code.
View 1 Replies View RelatedIn an application I have a Spinner that has tens of items.When the user taps on the spinner, a popup dialog appears that shows the list of possible selections. However, since there are (sorted) tens of items, I want the user to be able to use the fast-scroll thumb (like fastScrollEnabled attribute on ListView), similar to the one enabled in Contacts application.I tried to get the ListView that is used in that pop-up dialog, but I didn't find any methods to do that.
