Android :: Gridview To Scroll Horizontally?
Feb 12, 2010
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.

Say, a WebView with an html that scrolls vertically. What would be the basic steps to make it scroll horizontally (screen by screen)? Can't grasp the idea.

I currently have a GridView scrolling vertically, and everything works fine. But now that I want to change my layout and have the gridview grow on its width instead of height as it grows bigger I am lost. I have tried to simply change the column width each time an item is added to the gridview. But no vertical scroll appears, even though the items are added correctly. Is there a neat way to fix this, or must I make my own gridview?

I have a GridView in my activity, and I want to save current scroll position while user goes to another place and restore it while user comes back. I try to use GridView.getScrollY and GridView.scrollTo methods, but getScrollY method always return 0 instead of right scroll position. Am I using this method in a wrong way?
Could anyone who can teach me how to retrieve the scroll position in a GridView?
I searched the Internet found that someone said we can use getSelectedItemPosition and setSelection methods, but this requires user to select at least one item, how about the case that no items is selected?

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;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class TestActivity extends Activity {
@Override
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:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:text="Add Row"
android:id="@+id/AddRow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
<ScrollView
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);

is there no way to change the timeout to scroll in ScrollView? 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?

So everything is perfect about my Eris except that the scroll-ball doesn't scroll left anymore. This isn't the first time the problem came up. My last Eris had the same problem. It scrolls in every direction except which is kinda annoying as I use it alot more than I thought I would. Should I take it up with Verizon? It isn't a life or death situation but it makes editing sentences in texts a pain.

I try to arrange two buttons (with images on them which work fine) next to each other and to center them horizontally. That's what I have so far:

android:layout_gravity="center_horizontal|center">
<Button

android:drawableLeft="@drawable/accept_btn"

android:id="@+id/deny"

android:layout_toRightOf="@id/allow"
android:layout_below="@id/radioGroup"

Now my main problem is that I have X imageviews and when I align them all like that, and then use the android:layout_toRightOf="", they just start from the middle.

I 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]
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
><Button
android:id="@+id/Button01"
android:layout_width="188px"
android:layout_height="100px"
android:text="A"
android:layout_y="50px" android:layout_x="65px" android:textSize="48sp"/>

In every video I've watched either the phone is held vertically without the keyboard slid out or horizontally with the keyboard slid out.
Does the phone work horizontally without the keyboard slide out? Meaning, if you rotate the phone sideways will the phone rotate (as the iPhone does, sorry for the comparison)?
