Android :: Layout Weight Is Inconsistent For Horizontal And Vertical Orientation

Apr 8, 2009

I have played around a bit with the xml files for creating layouts and can't explain the behaviour of layout_weight when using it in a LinearLayout that has orientation="vertical"

When creating a layout that is horizontal everything follows the documentation, that a child would get more space if it's has the highest value.

But the following code for vertical orientation, give more space to the item with lowest weight.

CODE:..........

And the question is: Is this a bug or just a feature that maybe need more documentation?

Android :: Vertical And Horizontal Scrolling Together

Jul 7, 2009

is it possible to have both Scrollbars together. My Application is too big for just one of them. I tried it with a ScrollView in a HorizontalScrollView Layout, but it supports only vertical or horizontal scrolling at the same time and not crosswise. It would be nice to have a scrolling just like in the Browser of Android. Is this possible?

Android :: Scrollview Vertical And Horizontal

Jan 11, 2010

I'm really tired looking for a solution for Scrollview vertical and horizontal. I read that the any view/layout implements this feature in the framework but i need something like this. I need to define a layout within other, the child layout must implement scrolling vertical/horizontal for moving. Initially implemented a code that move the layout pixel by pixel, but i think that is not the right way. I tried with ScrollView and HorizontalScrollView but any ones work like i want, because only implement vertical or horizontal scrolling.

Oct 13, 2010

I am trying to use a ProgressBar as a metering like display. I thought it was going to be an easy task and thought that ProgressBar had a property to set to be vertical, but I'm not seeing anything. Additionally I'd like to be able to show ruler like indicator along the side of the bar to clearly indicate the current level.

Android :: Camera Display Horizontal / Should Be Vertical

Jun 9, 2010

I'm using a Nexus One and the Camera displays horizontal when it should be vertical and vice versa. I've no idea what's wrong. The code works fine on a HTC tattoo.

class Preview extends SurfaceView implements SurfaceHolder.Callback {
SurfaceHolder mHolder; Camera mCamera; Preview(Context context) { super(context);
// Install a SurfaceHolder.Callback so we get notified when
//the // underlying surface is created and destroyed.
mHolder = getHolder(); mHolder.addCallback(this);
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
} public void surfaceCreated(SurfaceHolder holder) {
// The Surface has been created, acquire the camera and tell
//it where // to draw. mCamera = Camera.open(); try {
mCamera.setPreviewDisplay(holder); } catch (IOException e) {
// TODO Auto-generated catch block e.printStackTrace();
} } public void surfaceDestroyed(SurfaceHolder holder) {
// Surface will be destroyed when we return, so stop the
//preview. // Because the CameraDevice object is not a shared resource,
//it's very // important to release it when the activity is paused.
mCamera.stopPreview(); mCamera = null; }

public void surfaceChanged(SurfaceHolder holder, int format, int
w, int h) { // Now that the size is known, set up the camera parameters
//and begin // the preview.
Camera.Parameters parameters = mCamera.getParameters();
parameters.setPreviewSize(800, 480);
mCamera.setParameters(parameters); mCamera.startPreview();
}

Android :: Crash On Rotation - Horizontal To Vertical

Feb 10, 2010

I'm playing around with android, and I'm creating a simple twitter app to test what I've learned so far. But I've run into a problem that I don't understand. I created a thread to fetch the tweets, no problems there, but then added a ProgressDialog to show when that thread was running. Doing so caused a very unusual behavior. If the user rotates from Vertical orientation, to horizontal orientation, program behaves as expected, no problems, but if he then rotates back, the program crashes saying a window leaked.

The problem only happens on a horizontal to vertical layout switch. I know of the issues of if you try to rotate while the dialog box is running, but I've made sure that the dialog box has finished running and dismissed before rotating and it will still crash. Heres my code:

package com.onesmartpuppy.puppytweet;
import java.util.ArrayList;
import com.github.droidfu.widgets.WebImageView;
import winterwell.jtwitter.Twitter;
import winterwell.jtwitter.Twitter.Status;
import android.app.ListActivity;
import android.app.ProgressDialog;
import android.content.Context;...............

Android :: Layout - Weight Not Working

Oct 4, 2009

LinearLayout obeys weight and as per documentation weight gives priority to an object. Here is the layout I have: Here you can see that the first textview has a weight of 2, second has a weight of 0, but still the second text view takes up all the space. If I give the first edit view a weight of 0 and second a weight of 2, surprisingly, first edit view gets more space. Isn't this weird, or am I doing something very wrong. I am poor in layouts. <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent"

Android :: Weight Sum - Layout Attributes Not Working

Nov 26, 2009

I have a simple horizontal linear_layout with bunch of image views in it. the trick is that the views have different widths, relative to the size of their parent (the linear layout). I set the layout's weightSum to a 100 and the layout_weight to let's say 10 of one view and 15 of the other, on so on. And it did not work. I also tired using float values setting the weightSum to 1.0 and the layout_weight of the image views to 0.2 and 0.3 and so on. But it didn't work either. I did search this group for any references to the weightSum but found nothing. Any ideas how to handle it?

Is is possible for me to have a keypad style keyboard when I hold the phone vertical and then switch to the qwerty keyboard when I turn it to the horizontal? If so, how do I do it? I just find that the qwerty is a bit too small for my fingers when it's squashed up in portrait mode.

Android :: Scrollable (horizontal And Vertical) ImageView With Buttons Overlayed

Aug 9, 2010

I want to implement an activity where the only thing you see is a big image, which can be scrolled horizontally and vertically.On Top of that image I want to display buttons, that can be clicked and trigger certain actions (like creating an intent to start a new activity). First I was thinking about a ScrollView, that has a FrameLayout as a child. The FrameLayout could have the image as a background and can have the buttons as childs. Because I know the position of my buttons exactly I could place them with absolute coordinates. Here is my first code:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<FrameLayout
android:layout_width="1298px"
android:layout_height="945px"......................

Android :: Scrollable Area Like In Robo Defense Game (both Horizontal And Vertical)

Aug 13, 2009

I'm trying to implement something very similar in my application, but looks like it's impossible to do this with standard components. I read several topics about such scrolling feature in the group, but all the topics ends with suggestion to write your own scroll view. I wonder did somebody implement such scroll view already? Or can somebody provide a brief how-to on this particular feature. I think any information on this would be very appreciated by many members of the group.

Android :: Slideit - Horizontal Word Suggestions Compared To Vertical Weird Choice Of Swype

Mar 24, 2010

Trying slideit and love the horizontal word suggestions compared to vertical weird choice of swype but:

1) do I really have to hit shift then question mark or exclamation mark each time to punctuate?

2) if I write a word, then put in a numerical, there is no space

3) if I want to go back and as a letter to am already formed word, there is always a space put in automatically, impossible to change a word like dog into dogs, comes out like dog s

4) contacts not in slide it dictionary

Very possible its my inexperience, live swype, hate the venice distracting word suggestion

Android :: Two Children For ScrollView Vertical Orientation?

Aug 10, 2010

I am trying to create a very simple application (part of my learning program), vertically oriented, with an EditText at the top that receives a URL, and two buttons side by side just below that say "Get Image" or "Get Text" depending on the URL typed in (.html vs. .png, for example). The resulting elements may be later scavanged for use in a real app. I know that ScrollView can have only one child. Conceptually, I want the rest of the screen to be a vertically oriented content region for displaying either the text (TextView) of the URL and "Get Text" was clicked or the image (ImageView) in the case where it was an image and "Get Image" was clicked. I tried to do this (pseudocode) in main.xml:

<LinearLayout> <EditText /> --where to type the URL
<Button /> --click to treat URL as text
<Button /> --click to treat URL as image
<FrameLayout> --(used to be ScrollView) <LinearLayout>
<TextView /> --content region occupied by either text
<ImageView /> --or an image (but not both)
</LinearLayout> </FrameLayout> </LinearLayout>

In order not to violate the single-child requirement. However, this doesn't work and for now I'm not finding any sample out there that clues me in to how best to accomplish this. The last complaint I got while debugging was:
Caused by: java.lang.ClassCastException: android.widget.TextView
