Android :: Use SWITCH Statement With SetOnClickListener / OnClick For More Than 1 Button?
Oct 1, 2009
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 ?
public void onClick(View v) {................

Most samples that I see appear to use an anonymous method in a call like button.setOnClickListener(). Instead, I'd like to pass in a method defined on the Activity class that I'm working in. What's the Java/Android equivalent of the following event handler wiring in C#?

I'm creating my first widget and ran into a snag. I have several buttons on this widget and need a way to register an onClick action for each of the buttons. 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?

I'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.
I'm trying to use a selector to make this happen:
CODE:...............
I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.
Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?

I'm able to add the entire power control widget but I'd just like to add the individual buttons like it had preinstalled in the first left extended home screen (WiFi, 4G, GPS and bluetooth). I'm sure I'm missing something terribly simple here but I've looked everything.

I just cannot believe whats happening with my brand new cell phone. Initially when i purchased it , this device started restarting. And when i complain to the SE they told me the battery connecter is damaged. So they sent my cell phone to Dubai SE. Got it replaced, and no restart yet. BUT the right side screen flickers and the switch on/off button is not working. So i cannot switch off my cell phone. If i remove battery and then again insert it, then phone start automatically without using the switch on button. What must be done, i have purchased this cell phone in Qatar and now i am in India. Please help this is so kinda heartbreaking

Two days back I had upgraded my X10mini to andriod 2.1. 24 hours after upgrade the screen got freezed. Its showing FM screen and the restart button is also not working. If I press the power button, screen lights on for some time and goes off. I can't remove the battery as the battery is fixed. Please let me know if you know some other way to restart the phone.

I have a strange issue. I am new to java/android but come from a programming background maybe I am just missing or doing something stupid with syntax here. I have a string variable called reportlength
String reportlength;
I then go: reportlength = intent.getExtras().getString("ReportLengt");
Now in my debug console for the variable reportlength it has it set as "d" (that is the correct value it should have)
At this point I have my if statement:

So I've got this code (updated for solution).
CODE:.............
The problem I was having was that one of the TextViews would turn grey when it wasn't supposed to. I tried fixing it by always setting the text to black again, but that turned every single one of them grey.
Until I tried:

Don't know why the latter works when setting text grey, but there it is. I guess I'm just a little retarded.

How can I enable assert statement on Android? I have referred to a url: http://android.git.kernel.org/?p=platform/dalvik.git;a=blob_plain;f=d... and done what it said: adb shell setprop dalvik.vm.enableassertions all but nothing happen! The test code is: Log.v("assert 1","1"); assert false; Log.v("assert 2","2"); No matter what I did, "assert 2" will be printed, which means "assert false" does nothing! What should I do? BTW, I use eclipse as IDE.

I'm developing an application that tracks the user's current position and stores it into a SQLite database. Everything works fine, but now I have the problem when querying the database for a track with more than 1000 records it takes nearly 1.5 minutes. On my Desktop it just takes 1 second. I know it's a query with many subselects but I wasn't able to get the right result another way. In my opinion this belongs to the aggregate functions like avg() and sum().
Here's my query:.................
