My Activity onClick() below doesn't appear to be doing anything (not seeing any string appear), yet I dont get any errors. What am I missing?
Is there a way to trace the function?

I have been teaching my self to "code" in the android language and java over the past few day. So I am new to this so please be patient.
Basically, my problem is I am trying to get a button on my form to open a web page.
Here is my java file.
Code:
Let's say I have a few buttons in a LinearLayout, 2 of them are:
mycards_button = ((Button)this.findViewById(R.id.Button_MyCards));
exit_button = ((Button)this.findViewById(R.id.Button_Exit));
I register setOnClickListener() on both of them:
mycards_button.setOnClickListener(this);
exit_button.setOnClickListener(this);
How do I make a SWITCH to differentiate between the two buttons within the Onclick ?

So far I've only found examples where they start a configuration activity from a widget button. Does someone have example code on using buttons in home screen widgets?

View 1 Replies View RelatedI have two activities. The first is a list where the user selects one of the items which takes them to a second activity showing the details of the item they selected. When the user clicks the back button I want the app to return to the first activity.
Is there anything special i need to do to make this happen?
Right now when I click the back button from the second activity it exits the app just like the home button would.
Here is how I am starting the Second Activity. startActivity(new Intent(getApplication(), SecondActivity.class)); finish();
the problem is that this button doesn't exit of my app... it simply closes the current intent ant returns to the previous intent (window) of my app.... how i can do a real exit/close button? i tryed with this:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
but it doesn't works, because when i turn back into my app, the app comes in the last opened window, and not in the first window of the app, how i can do that? i need that when i re-open my app it starts on the first window of my app
My first coding project is a soundboard type thing on andriod using eclipse (on 2.3.3)whats wrong with my code, I dont get any errors but the button doesnt play the sounds.
Code:
package com.mkyong.android;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;[code]......
I currently have an Activity that when it gets displayed a Notification will also get displayed in the Notification bar.
This is so that when the User presses home and the Activity gets pushed to the background they can get back to the Activity via the Notification.
The problem arises when a User presses the back button, my Activity gets destroyed but the Notification remains as I want the user to be able to press back but still be able to get to the Activity via the Notification. But when a USER tries this I get Null Pointers as its trying to start a new activity rather than bringing back the old one.
So essentially I want the Back button to act the exact same as the Home button and here is how I have tried so far:
CODE:.........
However the above code still seems to allow my Activity to be destroyed, How can I stop my Activity from being destroyed when the back button is pressed?
I have a simple list view with some check boxes in an alert dialog. I need to option to add a select all/none but you can't bring up the menu in an alert dialog, and I want to do this function from a button. From what I've seen any kind of button (positive, neutral, and negative) all close the dialog regardless.
So, is this possible? If no, what alternatives do I have? My last mitigation is to simply create a new view and recreate everything. Is a new view the best solution?
I have a views on the main class and many other class with an onDraw() method to draw a canvas.

I need to develop an application with downloads the data at the background and update about the progress in the front.
I guess this can be achieved using services and activity and passing data in between the. But, what I need to do is even if I hit back button and then start the activity again. It should check if the service is running or not. If service is not running it should start one else it should display the data from running service.
Something like music player where music is played by a service at a background and activity displays the information. Even on browsing through other activities of the application or hitting back, state of the music player is maintained.
Even though the end call is over 2x the size of my finger, it doesnt seem to work no matter how many time i press it! (most of the time).
View 5 Replies View RelatedFor the last 2 1/2 months, briefly pressing on the top on/off button would turn off the screen, but today something has changed and this brief press no longer works. Any idea which setting controls this behavior? I looked everywhere I could think off, used Spare Parts--all to no avail.

2. holding down the menu button still doesnt do anything
3. when you're charging your phone it doesnt show the percentage
4. cant uninstall where's waldo and midnight bowling.
5. sometimes you have to push the actual unlock button for the screen to turn on instead of any of the buttons (i do this to check the time)
never had the SD card or vibrating problems so i dunno if they got completely fixed.
I don't have KitKat yet, but I was reading the dialpad doesn't automatically pop up when you hit the phone button. Is there a way to automatically make the dial pad pop up instead of the search? If I want to search for a phone number I'll go into the internet. When I click on the phone icon I want the dialpad to be there. If there isn't a way to fix this then I might not upgrade my phone when the time comes to upgrade.

View 5 Replies View RelatedOver the past two days I've had a recurring problem with my Moment - the screen no longer shuts off when I press the Off or End Call button. This is a pain because buttons end up being pressed when I slip the phone in to my pocket. I'm running the official 2.1 update and have been since the week after it came out, and I haven't had this problem before. I can't seem to figure it out. The button still works to turn the screen on, and will still turn of the screen if it's at the lock screen, but at the home screen or in an app, nothing happens when pressing the button. This was a little awkward today when the body heat through my shorts opened up my Alarm Clock app and started playing the various alarm clock ringtones!

1. Weather will not update AT ALL! anytime you press where the weather widget it, it automatically takes you to the clock settings.

The problem - when viewing a webpage such as craigslist, if I click into an ad and then go back to the previous page my location on the previous page always defaults close to the top of the page instead of that last link I clicked. This is a very annoying problem if your a hardcore craigslist junkie like me because you can be you have to scroll back thru all of the ads you looked at just to get back to where you originally were.
Trying to fix the problem using two kinds of soft resets, a hard reset, resets followed by reinstallations of 2.1 ,etc etc, I finally went to a sprint store to get it checked out and the rep had a Hero that did the same damn thing! Apparently he didn't have a problem with his phone doing this because he just kept giving me some dumb blank stare.
1.5 never had a problem with web pages forgetting their locations when using the back button. Yet I haven't seen anybody else complain about this. Is anybody else able to recreate this problem? One thing to look for, after I reset the phone, reinstalled 2.1 or cleared the internet cache, the phone will do fine for a few minutes, recognizing pages like its supposed to, but after usually 4-6 times of clicking links the phone goes right back to forgetting locations.
I upgraded to 2.1. With 1.5 I had a phone I loved that worked fine and the only problem I had was a laggy phone-book, now I have a phone with a laggy dialer and that doesn't do web pages correctly. BTW, it does this with all browsers, not just the stock browser and Dolphin.
I've installed several apps that are supposed to have features that I can't even find. For example, I installed "Writer". This is supposed to have text formatting features (bold, italic, font size). But, after highlighting some text, I can't find anything that triggers a "Format" menu. A long tap on selected text will bring up a Cut & Paste menu. But if there's a Format menu, I haven't found it, yet.
I'm using Writer as an example, but I've tried half a dozen apps now that are listed as having certain features. Sometimes the program menu is the little checkerboard icon next to the Honeycomb task switcher at the bottom of the screen, but on many apps this menu is empty of anything useful. Some programs have an icon on the top of the screen that triggers a menu, but on others I've tapped on everything I can find and found no extra controls.
Is there some common screen gesture that I haven't discovered yet? Are developers listing future features that don't exist yet? Did Gingerbread have some context menu feature that's missing in Honeycomb? And is there some reason developers don't bother to provide a paragraph or two explaining how to use their product?
btw - I have an Acer A100 7 inch tablet, running generic Honeycomb 3.2 and downloading apps from GooglePlay. My device doesn't have a hardware Menu button, maybe that's the problem?
When your on the home screen and hold down the Menu button it doesn't open the keyboard.
View 15 Replies View Relatedjust a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]
