I'm running into some issues here with my app. I have 4 tabs run through a tabActivity. One tab sends an intent and run my ListActivity that populates the screen from a simpleCursorAdapter. My problem is that when I change back to this tab, after the first time its run, the list never refreshes regardless of the changes made to the database via other tabs. Is there something I can call from onTabChanged to refresh my ListActivity?
View 3 Replies View RelatedI'm currently working on my first android application. I am using a tabbed layout for my application. I followed the tutorial for this on the dev guide and ran into a problem. The tutorial only used three tabs, but I have a need for more. As such, the tabs resize and bunch up. I was hoping someone could tell me how I can make them scroll, like in dolphin browser when using multiple tabs.

I have to keep android:anyDensity="true" otherwise I've got a problem with re-sizing of the menus described here
As a separate question, my users can change the Locale within my app itself, I then "redraw" the menus using onPrepareOptionsMenu (Menu menu) to refresh the strings within the menu with the new language choosen by the user. Is there an equivalent for TABS (I have local strings within the Title of the TABS) or do I have to delete all the tabs and re-create them from scratch ?
We're in the process of writing an app that has 4 tabs: Map, People, Places, Events. The People, Places, and Events in the App show up as Icons on the map. By default the People, Places, and Events tabs each show a listview, custom rendered, displaying all the People, Places, and Events respectively.
Now, right now each of the tabs has as its content an Intent set to launch the corresponding activity. For instance, there is a MapTabActivity that extends MapActivity, a ShowPeopleListActivity that shows the people, and so on and so forth.
I see a lot of StackOverflow questions/answers saying that due to various limitations in the way the TabHost is setup, it's best NOT to use activities as the content of tabs. For instance, it's impossible to launch a new activity and have it take the place of the existing activity within a tab, whereas it's possible to switch out a View with a different view.
Now, I'm at a crossroads. We've (for better or worse) devoted a fair amount of time trying to get this app to work the way it's currently structured, with the Activities as the content of the tabs. When an icon corresponding to a Person, Place, or Event is clicked, it fires off a VIEW Intent on a URI corresponding to that object; this is picked up by an Activity that then shows the object. The same mechanism is at work both in the Map and in the individual lists. We really like the loose coupling this provides us; we just give a VIEW command and the URI to the person/place/event and it automatically brings us to the right activity. Granted, the activity that's launched covers up the tab view rather than appearing inside of that, but we were willing to live with this.
Here's an issue though: from the Show activity, we want to be able to go back to the map, centered at that person, place, or event. We can launch a new activity to show the map again, but now we have the map activity as the content of the tab, plus the show activity, plus the new map activity in the activity stack; given how resource intensive the map activity is, I'm guessing this is not the ideal way to go.
I guess my question is, is there a GOOD tutorial somewhere showing exactly how to do complex tasks with a TabHost? I've seen HelloTabWidget; I'm looking for something much more sophisticated than this. I'm worried that if we switch to the View based way of doing things, we'll have to do a LOT of housekeeping to intercept all the back events, try to switch out the views, etc., etc., as well as strongly coupling our program in a way we don't want.
I have an Tab Activity with 4 tabs. Each of tab is showing me the list view. Suppose i m on 4th tab and dragged the list view to the last position and after that i click on 3rd tab and again when i go to 4th tab it is not refreshing and showing me the last visible screen. Actually i want to show the list view again from 1st element. is tabs refresh automatically or we need to do it programmatic?

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.TableRow;

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);
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.
