Android :: EditTexts And Handles
Jan 26, 2010
I have an issue with an application I'm writing for Android. Here's the problem: I need to create several EditText fields on the fly, while still maintaining some sort of handle to each individual one. For example: I create four EditText's, and I wish to submit the information from them to a server via an HTTP connection. How do I get the user-inputted data out of these EditText's after they have been created? (I guess what I'm asking is how exactly do I use the setId() method, because it doesn't seem to be working for me).

I want to implement a custom input method for certain EditTexts within my app. I understand I need to extend the InputMethodService class, but how do I then add this to certain views? I've tried just using the class name in the android:inputMethod XML property, but this seems not to work. Using the SoftKeyboard example in the 1.5 SDK, my manifest is as follows:..............

<LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Layoutbuttons"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/Bsave" android:text="Save"></Button> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Clear" android:id="@ +id/Beditclear"></Button> </LinearLayout>
<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/Ledititems" android:orientation="vertical" android:scrollbars="vertical" android:scrollbarStyle="insideInset" android:scrollbarAlwaysDrawVerticalTrack="true" android:fadingEdge="vertical" android:fadingEdgeLength="8px"></ LinearLayout>
</LinearLayout>
I am adding dynamicly created EditTexts to the last vertical LinearLayout:
ArrayList<EditText> arrayedititems; edititems = (LinearLayout) findViewById(R.id.Ledititems);
arrayedititems.add( new EditText(globalcontext) ); //multiple times to add many EditTexts .... edititems.addView(arrayedititems.get(lastindex) );
Now all the edittexts are being added fine and show up on the linearlayout, the problem is I get no vertical scrollbar and can not scroll the linearlayout (you can a see large number of failed attemptes in the xml entry to enable this scrolling, such as forcing scrollbars or setting to vertical) Do I need to call some sort of invalidate() or notifyDataSetChanged() like with an arrayadapter to update the LinearLayout into checking if it needs to enable scrolling?

I have a layout with a spinner and a lot of textboxes and buttons.
I need to make appear some elements of the layout when one of the options of the spinner is selected and to make dissapear when other is selected. ----> PROBLEM SOLVED!!!
But also, i need to desativate some elements of the layout. I mean that they have to be visible, but the user can't press buttons or edit edittext's.

I need to input latitude and longitude separately in 2 EditTexts and display the location at the click of a button. Somehow I'm not able to get the correct layout as i precisely require 2 EditTexts aligned side by side and a button below them.
Here is what i already have code...

I am just wondering about how android handles sms when it receives them. More precisely my question is when the android phone receives a sms message, which application saves the message to the mmssms database? Is this done by the OS or by the native sms application?

How an android application handles updates ? What kind of information does the application usually needs to send to request an update, and what does it receives back ?

I have a HTC EVO 3D for months now and I've never experienced issues with it, but I aways have plenty of storage left and have done a system reset once so I don't know how it behaves. I'm very curious about this because I've explored some apps cache sizes and for example Facebook was about 50 MB. Is there a limit?
I'd like to know what happens when the internal storage runs out of space. Does Android (regardless of device / custom manufacturers "skins") automatically take care of deleting old cache files from apps?
I mean, if you run out of internal storage in a Nexus device, what happens?

Does anyone know of a Yahoo IM client that handles linked (AKA Aliases) accounts? I have tried the following clients:
- Meebo
- Palringo
- IM +
- eBuddy
- Nimbuzz
- Hi Yahoo
- Yahoo Droid
They all have the same issue which is: I have linked yahoo accounts (a primary with other accounts linked). When I log into a yahoo account with the above clients and I receive an IM to a linked account, I receive the IM just fine, but when I respond to the IM, it will send from the primary (or logged in) account and NOT the account that IM was sent too. What SHOULD happen is the IM should be sent from the account that the IM was sent too just like the desktop app works.

I have the following setup:
Desire
Aux Input (for music)
SuperTooth One BlueTooth Hands Free
When I drive, I use the HTC Desire to play the sat nav instructions and music out of the Aux to the stereo however, if I enable Bluetooth, all music and commands are sent through the Bluetooth receiver instead.
On the iPhone, you have the option to route audio through headphones socket or through the BT device - but cannot find out how to do it on the Desire.
Are there any applications that make it possible to route calls out via BT and everything else out over the Aux?

I'm writing an app which contains three tabs.. let's just call them TabA, TabB, and TabC.
In my main class which extends TabActivity I have a Bluetooth Adapter which handles sending and receiving messages. I initialize the BluetoothAdapter onStart. Part of the initialization tries to reference controls on the three tabs. But my problem is that only TabA (my default tab) has been initialized at this point so when it tries to access TabB and TabC, they're still null.. How can I initialize all 3 activities, and access controls on each of the tabs when receiving messages from the BluetoothAdapter? (Basically I want TabA to contain a TextView to log all messages, TabB will contain a few controls like sliders and checkboxes that will change based on the messages recieved, and TabC will just have an array of buttons that send specific data..)

I asked this in the other "Hero" subforum, but I thought I'd ask it here, too. I really like what I see from this phone, but I wonder how it handles multiple Gmail accounts. I have three Gmail accounts for different purposes. My iPhone 3G handles these with no problem. I don't see anything in the Hero manual that indicates that it will play well with multiple Gmail accounts.

I am pretty happy about that. The little summary pop up boxes come up and everything. There is no need for a app for that, just a bookmark for me.

I am trying to understand whether or not Android handles the phone conversation's audio stream or it is done outside Android's framework. Specifically, if, for example, Android controls a cellular processor that provides PCM interface for voice conversation and there is a need to send audio over Bluetooth instead of using mic/speakers, how this is handled? There are two ways here to the best of my understanding:
1. Route PCM from cellular to audio port on Android CPU, then let Android receive the stream and send it to BT stack for processing and eventually pushing to BT hardware over HCI 2. Have Android control a HW switch that will route PCM directly to BT HW using direct PCM interface Which one applies? Is there a preferable way (best usage of resources provided by Android)?

I've got the htc legend and its an awesome phone. I just wanted to ask to get an idea of how android works on relation to how it handles apps/processes etc. Using a task manager I see that tonnes of apps start when the phone boots. I see apps like app brain, msn talk,.radio, twitter app, stocks, footprints, maps and a whole plethora of others. What makes them start like this? What's the purpose? Do they have a negative impact on performance? It seems like all the apps listed see ones which have shortcuts on the home screen or related widgets. Is this how it works? Although they are listed date saree are they actually taking up system resources? And then there's ones like radio and stocks which I never use and don't have home screen shortcuts for, but they still start. Sometimes when mass kill apps (not processes) it sorta freezes for a while then has to reload the home screen. None of the apps I killed were essential ones, happens sometimes when I kill a bunch of third party apps. Would it be beneficial to kill most of the listed apps which apart on startup that I never use? I try to refrain from using the task manager but Coming from windows I'm just used to massacring all unnecessary processes and programs to keep everything clean.

Any thought on how the Marketplace handles the information related to the marketplace applications? I wonder if the request is posted to the marketplace every time client is started or if some of the available applications data is stored locally and refreshed by the background service.

I'm trying to open a dialog window, but every time I try to open it it throws this exception:
CODE:.................
I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached it since it seems like I'm missing something:
CODE:............
Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebSettings;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class myKMB extends Activity {
I already have JavaScript on the web browser on, the problem is the web view is acting to different from the web browser.

1- Does Android Browser (Éclair code base) support the "plug-in" or not?
2- Why "Google Gears" support is removed from the clair code base?
I searched the forum and came to know that earlier version of the Android does not support it at all? Here is the link for that, but this query asked in Dec'2008.

At first,I have a database created by using Ruby on rails.I just already implement insert function(HTTPPost) in my Android Application and it's work.But I don't know how to retrieve specific record from my databases and insert it back to specific record in Android (Like edit function in RoR)This is my insert code :
private void insertComment() {DefaultHttpClient client = new DefaultHttpClient();HttpPost post = new HttpPost("http://10.10.3.87:3000/comments");
// Configure the form parameters
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("comment[content]", t_comment.getText().toString();
nvps.add(new BasicNameValuePair("comment[id_account]", "1"));
nvps.add(new BasicNameValuePair("comment[id_place]", Integer.toString(position)I really try many ways out but it doesn't work and it takes very long time to fight with this piece of code. Actually, I really don't know how to specify RowID to HTTPPost.

I released updates of my apps yesterday and they are being hidden from android 1.5 and 1.6 phones.
This is due to a Market bug which hides apps with bluetooth permissions from android 1.5 and 1.6.
Come on Google fix the market. We spend countless hours making are apps work on ALL android versions and now you do this...
This issue has been raised since June, but has only affected me since i made an update to the market yesterday.

I'd like to add a menu option to the Android camera app. Is this possible to do using the current SDK? I know I need to add an intent-filter tag in my activity. But I don't know what I should put in the mime type. I want to be able to process the live camera previews if the user selects the menu option. So what do I put into the type tag of the intent-filter? Also I suppose I won't be using ALTERNATIVE or SELECTED-ALTERNATIVE for the category as I want to deal with the whole intent?

I was wondering if the market checks if the application can be installed on the device. For example, if I have an Android 1.6 and if I try to install an application with :"<uses-sdk android:minSdkVersion="7" />" on its manifest. What will happend ?
