I know this is possible as the built in clock app and other apps are able to do it. How do you turn off the button backlights from code? These would be those like the softkeys on the bottom of the Nexus One screen.
Update: Found this, but it only works on Froyo: WindowManager.LayoutParams lp = getWindow().getAttributes();
lp.buttonBrightness = 0;

Does anyone else get annoyed by the bottom button backlights going out too quickly? Is there anyway to lengthen the time on that? It really is annoying to be surfing in the dark and not being able to see the menu button. Wish it was on the same timing as the main screen.

View 2 Replies View RelatedIs there any app/hack/widget to keep the backlights on the bottom buttons on just as long as the screen is backlit? So annoying how quickly they go off. Equally as annoying is how quickly the screen goes to sleep after you get a text. It literally stays on for 2 seconds, so I have to press the power button then slide/unlock to get to my text. Needs to be an option to keep it on for longer (10 seconds).

View 2 Replies View RelatedI was wondering how we could add objects such as textview and radio buttons to the activity through code and not the XML file and still have it run correctly. I tried adding a simple textview below but I got an error when I tried to run. Can any1 tell me how I could add the textview in correctly? import java.util.ArrayList; import android.app.Activity; import android.os.Bundle; import android.widget.ScrollView; import android.widget.TextView;public class Q_end extends Activity { /** Called when the activity is first created. */ private ArrayList<String> qs = new ArrayList<String>(10); private ArrayList<String[]> as = new ArrayList<String[]>(10); @Override public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); setContentView(R.layout.end_app); ScrollView we = (ScrollView) findViewById(R.id.viewer); String[] temp = new String[4]; temp[0] = "the"; temp[1] = "the1"; temp[2] = "the2"; temp[3] = "the3"; as.add(temp); String temp2 = "the rocks says"; qs.add(temp2); qs.add("the question is"); String[] temp3 = new String[1]; temp3[0] = " "; as.add(temp3); TextView gg = new TextView(null); gg.setText(qs.get(0)) we.addView(gg);
View 4 Replies View RelatedI can't seem to find anywhere a way to programmatically change the the alignment of the button.
In the XML it is simply layout_gravity="Center" or something.
How do we do this in the code?
LayoutParams do not seem to cater for this.

View 1 Replies View RelatedI was trying to do a memory game on android, but i can't figure out the code that matching 2 button with the same image..
CODE:..................
First of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?
View 1 Replies View Relatedmy android phone's power button stopped working a few weeks ago. It wasn't a big problem, but a few days ago, the battery died. Now it is turned off and I can't turn it on. When I put it in charge, it just shows the charging screen. The phone is a Winmax W8000 (Winmax is Bangladeshi company. I'm from Bangladesh). It runs on Jellybean (4.1). It wasn't rooted. I tried to get into Download mode, but pressing the volume buttons and plugging in the charger doesn't work.

View 6 Replies View RelatedI was waiting for Passion for months after reading posts here, literally coming here every day for rumor confirmed, but you all know that's history now. In the stock browser I can turn page by flicking finger on the screen, but isn't using hardware rocker much more precise? Is there a way to do that? In dolphin the rocker sort of does that, but it makes an annoying beep as well. I can turn off sound beforehand to avoid that, but it's easy to forget to turn up sound afterwards. I migrated from HTC 6800 (WM6), the rocker smartly only changes volume when using the phone, while in other situations it smartly turns page instead. Can Droid be up to that?

I can use it to turn on the screen. And I can hold it on to power down, airplane mode, etc. But pressing it once does nothing when the screen is lit up. I have tried wiping all data from the boot menu. This restores the functionality, but when I restore all my data and apps (MyBackupPro) the problem returns.
