In my android application i am using a table inside a scrollview but am not able to scroll horizontally if the length of content is more.
Could you please let me know any solution for this?

I am just wondering if the children of gridview can be shown horizontally instead of vertical view.
Also I have question on performance issues on how horizontal scroll view works.
I have to show 1000 objects and for this I have to create objects and add it to view and scroll view works fine. This seems a lot of memory is there a way we can make horizontallscrollview behave like gridview so that it request for only particular objects to be created when needed.
I'm finally getting around to fully customizing my phone.

document.getElementById("myDiv").innerHTML += "line " + myLine + "<br>";
...............
<div style="position:...etc; overflow:auto;" id="myDiv"></div>
this works without a glitch in every browser on all non mobile platforms. However... when this is implemented on iPhone (Safari) or Android (webkit) the div gets filled up with the text but no scrollbar is generated when the text runs past the height of the div and the user can't "push" the content down either. So effectively overflow is always "hidden" no matter what. I'm curious if there's some alternative approach that I'm overlooking or if this is just a bug I have no way to get around at the moment.

I have a WebView inside the ScrollView. The content of WebView dyanamically changes when it displays different html page. I have the following issue: For example I have A.html, and B.html. The content of B.html is larger than A.html, so the page is longer. When WebView load B.html, the ScrollView stretches its size to enable itself scroll for B.html, then if I go back to A.html, ScrollView doesn't resize itself. (The scroll area is exceed the content of A.html) What I want to have, is dynamic change the scroll area of scroll view to fit the webview's content.

I'm using data to build elements of a ViewGroup. The ViewGroup are LinearLayouts, except the leaves, which are TextViews. Because Data draws the hierarchy, I inflate the LinearLayouts and TextViews from individual XML files programatically on the fly.
My Problem:
When I create a LinearLayout with the attribute wrap_content, then inflate a TextView or other LinearLayout into it, I can't get the parents (or enough of them, anyway) to redraw, respecting the new view. These LinearLayouts always seem to come out at 0 size, because when they are first created (before their children are inflated), they wrap around nothing. I've tried calling some stock methods of ViewGroup but nothing seems to work.
I currently have a Nexus s, and ever since I upgraded to ICS I am no longer able to view flash content with Opera Mobile. It works fine with the stock browser.

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;

public class TestActivity extends Activity {

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.AddRow)).setOnClickListener(new View.OnClickListener() { public void onClick(View v) {
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"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"

android:text="Add Row"
android:id="@+id/AddRow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />

android:id="@+id/TableScroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@id/AddRow"
android:layout_alignParentTop="true" >
<TableLayout
android:id="@+id/Table"
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);
It looks like the standard ScrollView does not support horizontal scroll. Has anyone implement a ScrollView with horizontal scroll support? It would be appreciated if you can share it.

I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

View 6 Replies View RelatedI currently have three different phones, a Google ION, HTC Evo and a Droid. I've been receiving reports of weird bugs since 2.1 was released, I'd hoped they'd magically clear with 2.1-update1 but they haven't. The bugs are for specific devices and can't be tested in the emulator. On the Droid, I had a reoccurring loop when the device was started and held horizontally. Didn't happen on any other device. On the HTC Evo and Incredible, odd freezes when the screen was panned. Didn't happen on any other the other devices as far as I can tell.
None of these problems caused a crash or even an error in the log. They just caused the app to act weird. Testing with the physical devices for these bugs is absolutely critical to resolving these issues. I found the Droid problem easily, that one is fixed. The HTC problems still are present but I've managed to mitigate them with some clever programming. Regardless of how things are supposed to work, in the real world, having the actual devices in hand makes life a lot easier. It would be great if the device manufacturers would create some sort of program where we could get our hands on these things without signing up for contracts or paying $500+ for each one. They could be units that didn't pass quality control, scratch and dent models or returns, as long as they worked on WiFi, that would be all that's necessary.
I've been racking my brain (android newbie here, so not hard to do) for awhile trying to figure out how to accomplish this: Desired Layout using a Relative Layout or something other than AbsoluteLayout which is what this was created with. I'm coming from a Windows programming background where the device adjusts the 'absolute' positioning for you and GUI layout was a non-issue.The first layout works great in the emulator, but doesn't format for my Nexus One or any other screen that differs from the emulator size. I expected this because it's absolutely positioned, but haven't found a solution that will format correctly for different screen sizes. My goal is to have the layout work for different screen sizes and in portrait / landscape. Here's the Code that I'm currently using: [main.xml]
