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!

In an Android app, I am looking for the functionality of the .NET string function [Trim('aaa')] which will trim off the text "aaa" off a string. I don't think this is natively available in Java and I haven't seen that functionality in Android Java textutil library. Is there an easy way to have a Java app trim a set of characters from the string?

View 2 Replies View RelatedI'm very new to java and am working on my first Android app. I am using the webview demo as a template. I am trying to generate a random integer between 1 and 12 and then call a certain javascript function based on the result. Here's what I have:
int number = 1 + (int)(Math.random() * ((12 - 1) + 1));
number = (int) Math.floor(number);
String nextQuote = "javascript:wave" + number + "()";
mWebView.loadUrl(nextQuote);
So mWebView.loadUrl(nextQuote) will be the same as something like mWebView.loadUrl("javascript:wave1()") I just want to know if what I have here is correct and will work the way I think it will. The application isn't responding as expected and I suspect this bit of code is the culprit.

I am currently trying to integrate a live search functionality in android. I use a customized Autocomplete widget. The widget itself provides me with a threshold to only start a query after a certain amount of characters have been typed in. But what I also want is that a query only starts, say if a user has stopped typing for 2 seconds.
As I load my contents with a AsyncTask I tried blocking the doInBackground function by calling Thread.sleep() right at the beginning. If the user would then continue typing the program would look after an existing task, cancel it and start a new one. This was my idea. But it doesn't quite work the way I expected. Sometimes it sends out queries even if the user is still typing, sometimes queries are canceled after the users stopped typing. Do you have any ideas on this or maybe a better way to solve this? Here are the code snippets:.....................

View 4 Replies View RelatedI would like to compile a list of Android phones that either
1) Comes with native call recording functionality.
2) Support call recording with 3rd party applications.
It would be great if you can lend a hand.Please note that phone/apps that require using speakerphone to record the calls do *not* count. That's a ugly hack I consider marginally useful.Please don't bring legality discussions here as well.Models that have this function built-in.Samsung Galaxy S (South Korean version SHW-M110S, with firmware DH09 or newer).Models that don't have this function built-in but can use 3rd party app to record calls in both ways without turning on speakerphone.HTC Magic (a.k.a. G2); requires root and custom kernel; with rViox
Does anybody know how can I get the build-in function call trace on Android phone?

View 4 Replies View RelatedIt's possible to specify a particular function to be called when button is clicked by setting its onClick attribute in xml:

I want to do something similar for FocusChange of buttons, is this possible?
Specifically, I wish to increase my button's size when it has focus and make it normal sized when not focussed. To apply this to all my buttons, I hoped to call a specific function which does this and then specify this function name in my style.xml. But there is no onFocusChange attribute in android.
It works when I add overriden onSetFocusChangeListener for each of my buttons separately in the code. But is there any other solution?
