Has anyone figured out how to scroll the contents of the Layout Editor when those contents overflow one "screen"? I'm talking about at design-time while using the ADT Layout Editor, not scrolling at run-time on a physical device (that works fine).

You know that layout editor in the Android ADT plugin that lets you design the layout for ADP1, ADP2 and Nexus One, has anyone created other device configurations? It requires device information such as the x-dpi and y-dpi, which can be difficult to find out. I'm just wondering if anybody has added more device configurations they're willing to share? Perhaps together we could compile a huge devices.xml containing many of the devices out there. I'm fully aware the layout editor has many faults and cannot be relied upon but it is sometimes useful to rapidly preview how the layout might look on a wide variety of devices without switching between emulators.

Eclipse 3.4 The problem is I have a project in workspace that has been developed under JDK 1.6.I don't really want to switch back to 1.5 ( i' would have to clean up a LOT of @Override ) but if i work with this project, after couple of rebuilds - eclipse layout editor not able to display preview. Work around i found so far open android project that is in compliance with Java 1.5. Close everything else and rebuild workspace. But it's kind of annoying to do it every time.
View 2 Replies View RelatedI'm porting an app of mine to work better with API 1.5, and I'm having problems with the layout files where I'm using an AutoCompleteTextView (and, naturally, MultiAutoCompleteTextView). Whenever I have them present in a layout, the graphical representation of the layout disappears, and "NullPointerException: null" replaces it. Is there any way I can view a widget such as this in the Eclipse editor? It definitely worked in the 1.1 SDK, otherwise I wouldn't have used them.
View 2 Replies View RelatedThis is probably related to this question. I want to know if anyone else gets the same error as me and if there is a way to get around this. I did the following: Followed the instructions from this page. From the top, go to File -> Create a new project -> Android Project -> Create project from existing sample. Checked Android 2.2. From the drop-down menu picked SkeletonApp. Clicked finish. From the package explorer, went to SkeletonActivity -> res -> layout -> skeleton_activity.xml. In the tabs at the bottom of the editor area (editor area is the center of the screen) clicked on Layout. Then I got the error "ClassCastException: android.widget.EditText cannot be cast to andoid.text.ViewGroup". The full text of the error message is given below.

I'm new to Android & Eclipse. I've downloaded Eclipse and the Android ADT and created an ultra-simple "Hello World" app (has only auto-generated .java and .xml files). Eclipse CRASHES (closes after a very brief pause) when I do the following: In Package Explorer, select AppName/res/layout/main.xml Press, or double-click, or 'Open With' then 'Android Layout Editor' (The app runs OK in the Android emulator) My configuration is:
Android Development Tools 0.9.5.v200911191123-20404 com.android.ide.eclipse.adt.feature.group
Eclipse IDE for Java Developers 1.2.2.20100216-1730 epp.package.java
Windows XP
Can someone tell me what I'm doing wrong or what's wrong with my configuration? Any suggestions on what to check? For any non-trivial app development I need to be able to use the Layout Editor. More ... I can select main.xml and Right-Click and 'Open With' any of: XML Editor, XML Schema Editor, Text Editor -- with no problem. The problem is limited to Android Layout Editor.
In the layout editor in Eclipse, I have created a custom view. For some reason, there are a few methods which cause NoSuchMethodError exceptions in the code. Here is the code in the initializer of the custom view:.............

View 2 Replies View RelatedI 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);

View 2 Replies View RelatedI thought ADT should come with a visual editor for building GUI : http://stackoverflow.com/questions/851882/easy-way-to-build-android-ui However, I just cannot find it. I was wondering where is the Visual Editor for Eclipse with the ADT plugin. I can run HelloWorld application without problem. However, whenever I click on main.xml at the left navigation tree layout folder, here is what I get. What I wish to get is a WYSIWYG editor.
View 4 Replies View RelatedIs there an explanation of the ADT layout editor UI some place? I can't find anything on the Android web site about it. When I look at a layout in the design view, there are a number of fields at the top with labels like MCC, MNC, Lang, etc. I've noticed that I can change the contents of these fields, such as orientation, and it has an effect on the view. But a yellow warning triangle appears next to the field I've changed and the next time I open this view I see the unmodified field. For example, if I change to landscape orientation the view goes back to default next time. Is there documentation some place on what these fields mean and how they are supposed to be used?

Is there a (simple) way to completely and utterly disable all Java formatting in the Eclipse editor?
That is an Eclipse question, but I appreciate your indulgence because this problem is slowly driving me insane. I am spending a lot of time fixing code to make it look good again after it gets mangled by the automatic formatting. I thought I had removed all formatting keyboard shortcuts, but I missed something because my code keeps getting changed. I suspect the culprit to be the SourceFormat menu option because that can be triggered by Alt-S-F which is very close to Alt-F- S, the File/Save command.
So a little finger slip and code mangled. Unfortunately, the mangling is not always done where I am looking (since it is applied to the entire file), so I don't always know to undo it. Is it possible to disable or remove a menu item?

View 3 Replies View RelatedI had Eclipse running with the Android plug-in and I decided to add the Emacs plug-in. I downloaded and it worked. Then I decided to go back to the Eclipse key bindings and the Android plug-in disappeared. I could not update it, because Eclipse said it was installed, but it was not showing up in the menu.
I had to re download Eclipse, and reinstall the plug-in.
Why don't different plug-ins cooperate? I had the same issue when I tried to download the Blackberry plug-in alongside the Android plug-in (in different workspaces) and that also did not work. The only solution is to have two separate Eclipse each with a different plug-in.
1. Can I call ADT Layout Editor in my java source file, not by XML file "open with" menu ?
2. When I click "add" button in the outline view of ADT Layout Editor , it will show such a list of UI components as "AbsoluteLayout AnalogClock AutoCompleteTextView Button ....." My question is where it gets this list? Can I config this path to get my customized UI components?
It seems that Android is very buggy compared not only to the iPhone, but to pretty much any other software. It's not just minor bugs either - pretty much every developer will come across many serious bugs. Some examples:
- When you run the "sdk setup.exe", the very first thing that happens is that it informs you that it can't connect using https, so you have to change the options to use 'http' instead. This appears to be a bug in the .exe rather than any kind of user issue because the https url works fine in the browser and this error seems to affect everyone. Sure, it's trivial to work around (just do a google search and you figure it out in 5 seconds), but the user shouldn't have to do that. It makes it look unprofessional.
- When you view a TabWidget in the layout editor it crashes.
- Every time you run an app in the emulator, it starts off with the screen locked so you need to press the Menu key.
- Various socket bugs (or perhaps all the same bug) related to IOException not happening. Even something as simple as just trying to connect to a remote host that is not listening will cause it to hang instead of immediately returning an error.
All of these bugs have been logged for months (some by me, some by other people) with no indication of any fix.
At the moment I'm just using the emulator, but I'm wondering if the phones themselves are this buggy or if all the bugs are just in the development environment and emulator.
Is it normal for my Eclipse to totally freak out when I plug more than one phone in at a time?
Either my Hero or my Droid work fine solo, but if I try both at the same time they both become unrecognised and I have to then restart Eclipse (2 minutes of waiting) before I can go back to using just one phone. Kinda sucks having to unplug and re-plug phones all the time. I have 8 USB ports and no specific combination I can find seems to help.
Plugging in more than one phone also crashes my DDMS.
I am new to android development and have been playing around with the tutorials offered at developer.android.com.I don't have a problem with projects I create from scratch, but when I start a project from the android sample code provided at android.com or from any other android project, I can never seem to get the bugs out to even run the thing.For example, when loading up the NotePad sample in the android-7 package of samples.would like a general solution, something more global bc this is occurring whenever I pull in anyone's source code from outside.kind of frustrated because I feel that I am spending too much time working out these kinks and not being able to study other people's code against how it performs in the emulator.
