My lovely Droid Incredible seems to enjoy scrolling side to side when not in use. It's becoming a bit annoying, as I do not wish to set up either my email, schedule an event or stare at just the wallpaper. I'm afraid that this is taking a toll on my battery.

you know how you can scroll sideways from screen to screen? i want one of my screens to be Handcent Sms instead of just having it as an icon....is this possible? If it is, how do I do it?

View 3 Replies View RelatedI have text area and and down to that "ok" and "cancel" button. when i click on text area keyboard appear and focus on the text area and buttons get hide behind the keyboard.
I want when text area get focus scroll a little bit and also display the bottom buttons while text area id selected.
I am using a table layout in a screen. i need to have both horizontal and vertical scrolls. By default i am able to get vertical scroll in the view but horizontal scroll is not working. I am using android SDK 1.5 r3
Ihv already tried android:scrollbars = "horizontal". I hv read on some forums that in cupcake update horizontal scroll is possible in andorid.
I've got this odd problem which is happening on 1.6, 2.2, and a MyTouch 3G Slide (which is API #7, and listed as "2.1-Update1" in the Android Device Chooser). If anyone can explain what I'm doing wrong & how to fix it (or possibly confirm that this is an Android bug)The basic idea for my app is to make a stopwatch-sort of thing, in that the user can tap a button to start a timer, then tap it again to stop (pause) the timer; further taps alternate between resuming the timer and pausing the timer.I've got a top-level ScrollView which contains a RelativelLayout, which contains a bunch of widgets. The first widget is a HUGE button (so that it's easy to press), which pushes all my other widgets below the bottom of the screen. This is intentional, as I want to rely on the ScrollView (and an on-screen reminder to the user) to make the rest of the input options available.I've got a simple state-machine type setup, where mState is the current mode (STATE_ TIMER_ NOT_ STARTED before the user presses any buttons, RUNNING after the first press, and then PAUSED after the second, back to RUNNING after the third, etc, etc).
All this works great EXCEPT that when the timer is running, and the user presses the start/stop/resume button again, the ScrollView will scroll down a ways. I am NOT issuing this command (I don't even have a reference to ScrollView object), and I'm not sure why it's doing this.
REPRO:Compile + run the below samples. When the app starts, press the 'Start Timing' button. Use your thumb (or the mouse) to touch-drag the screen upwards (so you can see the RatingBar), then drag it back downwards (so the button is again completely on-screen). Tap the button (which now reads 'PauseTiming') again, and it'll jump down a bit. It should NOT be jumping/scrolling down, since there's no statement (that I can see) that tells it to scroll down. As near as I can tell, it's the setText that causes the scrolling ( when I comment those lines out, no scrolling occurs).WHAT I'M ASKING FOR:if I'm doing something dumb & you could point out what it is, I'd really appreciate it! I wonder if 'touch mode' might have something to do with this, since it does NOT appear to happen (in the emulator) when I use the mouse's scroll wheel to move the panel upwards (i.e.,instead of the simulated finger-dragging). I can't find a whole lot on touch-mode, and nothing specific on focus/selection in touch mode within a ScrollView if you can confirm that this error occurs for you too, that would be ok, too (since misery loves company.AHEM I mean, since it might help confirm that it's not just me MyTestApp.java package bug.android.scrollview;

UPDATE 1: Adding if( btnStartStopResume.isInTouchMode() )
Toast.makeText(this, "TOUCH MODE", 2000);
elseToast.makeText(this, "NOT touch mode", 2000);
then setting breakpoints in the debugger confirms that the button is always in touch mode (regardless of whether I finger-drag the panel up/down, or mouse-wheel it up/down). So it's a combination of being in touch-mode AND finger-dragging the panel after the 2nd button-press (i.e, when the app is in 'stopped/paused timing' mode) that's causing the odd extra-timing in subsequent pauses.
UPDATE 2:
I just noticed that it's scrolling down to the EditText, and no further. It looks like when you move the panel down the EditText gets the selection, and after the click event the ScrollView scrolls back to the thing that has the selection. Seems to explain why the mouse-wheel approach doesn't have this problem (it moves the selection/focus back up to the button).
I want to have a dynamic table, with rows added over time as a result of user interaction, using a TableLayout inside a ScrollView. This works fine, but when I want to scroll to the end of the table using fullScroll(), it always leaves out the last line; that is, it scrolls so that the one before the last one is visible. The last line is visible when scrolling manually, and the scrollbar is correct too.I'm of course open to suggestions as to how to make a better layout out of this; but I'm specifically interested in understanding why fullScroll() behaves that way. Should I give it a different parameter, or use something else altogether? Or does it do that because the newly added line isn't yet visible somehow? (if so, how can I solve that?) Or did I miss some other obvious thing?The following code replicates the problem: TestActivity.java:
package com.example.android.tests;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ScrollView;

setContentView(R.layout.main);

Random rnd = new Random();
TableRow nr = new TableRow(v.getContext());
for (int c=0; c<3; c++) {
TextView nv = new TextView(v.getContext());
nv.setText(Integer.toString(rnd.nextInt(20)-10));
nr.addView(nv);
}((TableLayout) findViewById(R.id.Table)).addView(nr);
// Scrolls to line before last - why?
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
}main.xml:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0,1,2" />
</ScrollView>
</RelativeLayout>
Edit: for reference, I implemented Romain Guy's solution as follows:In TestActivity.java, replace:
// Scrolls to line before last - why?
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
// Enqueue the scrolling to happen after the new row has been layout
((ScrollView) findViewById(R.id.TableScroller)).post(new Runnable() {
public void run() {
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
Every now and then, I get this weird screen when I press the home button on my Galaxy W.The only way to exit this screen is to press the back button. Sometimes pressing the home button again will bring me back to this screen.The first few times it did this, it prompted me to run it through either Accuweather or Clock. After I deleted Accuweather, it defaulted to running through Clock, as seen in my task manager.
View 6 Replies View RelatedI've had my Incredible since 4/28, and everything has been working smoothly up until about last Thursday night when it just restarted out of the blue while I was listening to music. Then right after it booted up, it restarted again, then again about seven more times. I got fed up and took out the SD card and it seemed to stop after that, so I haven't put the SD card back in since then.
Just now, Wednesday, about a week later, I was browsing around on the internet and all of a sudden, it restarted, and then again, and again, and again. I've read that it is because of poor signal strength or something like that so I had just enough time to put it in airplane mode before it restarted again.
Side note, that theory about it being caused by poor signal seems to make sense because the first time it happened to me I was out of town in a city that gets very bad coverage with Verizon, and now today when it started happening again was at my house where for some reason I get very bad service with the incredible, my old phone worked perfectly fine in my house but the incredible gets terrible service, and so does my brother's Droid. In fact, about two weeks ago I got my first dropped call on Verizon in about three years, and it was in my house.
So anyways, I decided to put it in airplane mode, and just after I put it in airplane mode it restarted again. Then when it booted back up my Helix Launcher 2 home screen went back to the standard Helix Launcher 2 icons, I go into my messages and everything is gone, my contacts are all gone, everything is gone. I go to the app menu and all my apps are still there, but when I start up an app, all the custom settings are default now. I went into the settings and my accounts are all still there. I click on internet and I get a terms of service agreement, it's as if I am booting it up for the first time, but for some reason my apps and accounts are all still there.
I turn airplane mode off thinking it might have something to do with it not being connected to my google account, and I restart it again and everything is still gone. I don't know what to do, has this happened to anyone before? I feel like there should be a way for me to get this stuff back since my apps are still there and my accounts are still synced, but random things are missing like my contacts and messages etc. This is really starting to get annoying, I have insurance and everything, but I really don't want to exchange it for another one because I've read that other people who have had there phones replaced have still had the same rebooting problem, even after going through multiple replacements.
I have a listview that when scrolled and the items go off of the screen they are not redrawn when I scroll back to them (the text and checkbox). In fact, items that are off the bottom of the screen in the listview never get drawn when scrolling to them. This only happens in Froyo. Any other version it works just fine. I have checked and the data is there as expected in the adapter when the getItem method is called, it is just not visible. The listview item is there (it's occupying the same amount of screen space per item), I just cannot see the text or checkbox once scrolled off screen and back on again. Code...

View 4 Replies View RelatedI'm trying to show a ScrollView with a button anchored to bottom of screen. This is coded programmatically (without using XML layout for now). The trouble is when the ScrollView has many items (requiring scrolling), it prevents the button at the bottom from showing. The bottom button is sort of pushed off the screen. Look at the code below. I have a TODO which mentions a workaround to specify the exact pixel height of the ScrollView, but this is not a good solution. If you change the for loop to add only 2 buttons, then the bottom button will show. So how do I make the ScrollView show a scrolling list, with the bottom button in view, and without specifying an exact size of the ScrollView? I've seen some discussions here:

In the source, it's set to: static final int ANIMATED_SCROLL_GAP = 250; so any drags will be blocked for 250ms. This has the appearance of the ScrollView being stuck for a bit before it moves. This makes small scroll gestures difficult to work with. There's no way around this?

View 14 Replies View RelatedSo far, I love the Evo, but I am having three problems with it. And they are getting annoying. First off, some applications will randomly terminate. It started out being regular downloaded applications that would just end. Whatever, it was bearable albeit annoying. But now, sometimes important applications like "Touch Screen" (I don't think that's the exact name) are starting to terminate randomly. That made it so that I couldn't text (rebooting the phone restarted the application).Two, I seem to manage to accidentally press the screen in a random place just about once per minute when I'm holding the phone. It's getting to the point where I feel like it's starting to push random buttons when I just press the sides of the phone. I don't know, it's tough to describe. Also, there seems to be some other shortcut screen that pops up every so often. It's a small box in the middle of the screen that shows my six most recently used apps. I have no idea why it pops up, or how, but I would actually like to use it if I could figure out how to do it.
Three,lastly, it seems to lock up a lot. It just freezes, just like a computer would. It's probably done this about ten times now.So is anyone else having any problems like this? It's starting to get very annoying. Big blemishes for such an amazing phone... it makes me sad to think this has so many interfering problems.
Does anyone's app screen stutter slightly when scrolling? If you quick flick to the bottom it seems somewhat ok but if you slow-scroll it seems to stutter. It just isn't as smooth as my iPhone. It's not terrible but comparatively annoying.

View 4 Replies View RelatedI noticed this same issue with my HTC Hero, and then it seemed to go away. Now I've noticed it again.
The issue is this: I have around 2700 songs on my SD card, all in a folder called Music, and they are arranged, quite logically, by artist and album under that. Unfortunately, when I put the music application on random, it seems to get stuck on 4 or 5 artists (and sometimes within those artists, one particular album) and play those almost exclusively, with only an occasional diversion to some other artist. At one point it was so bad that a. it played one particular song 6 times in a 4 hour period, and b. I got so tired of one of my artists, I deleted it entirely!
So, is this a bug with the built in music player? Is it because of the amount of music I have? Is it because of where my music is stored? Has anyone else had this problem? (Or does Android OS just have an affinity for The Byrds? )
Are there any other music apps I can try? I tried Simply Music, and it did work much better on the randomization, but it hung for a few seconds several times (for no discernable reason) and it is very slow to load.

However the ScrollView does not work as the links in the TextView are activated instead.Is there a way to combine a ScrollView and TextView so that both the scrolling and links in the text work?
