Android :: Button Not Centered Vertically In LinearLayout?
Feb 3, 2010
I have a LinearLayout, which only contains one button. I want this button to be centered vertically and aligned to the right. I tried many ways, but I couldn't make this button centered vertically. It is always aligned to the top. I also tried to put a button in RelativeLayout, the button can not be centered vertically either.
The XML is as below. Is there anything wrong with this layout?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#E8E3E4">
<Button
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:text="More" android:layout_gravity="right" />
</LinearLayout>

1) A ListView with many items (i.e. scrolling will occur at some point)
2) At the beginning, the selection is at the top (item #0)
3) User is scrolling down (i.e. we're not in touch mode)
4) For the first items, the selection is moving down without the list to scroll.
5) Once the selected item is reaching the middle of the list's viewport: the list starts to scroll-down.
6) Then, toward the end of the list: scrolling stops and the selection keeps moving down until the last item is reached.
It's a common feature in (keyboard-enabled) UI frameworks but I don't believe it's possible to achieve with Android, as for now... Right?

I made a custom alert dialog box to be displayed at the end of my game so that the player can enter its name to save it. The problem is when I call show() on the dialog appears but it's not vertically centered! It's a bit lower than it should and no matter what properties I set in the xml or when using setGravity().
I think it's the same problem as stated here: http://bit.ly/9tk0ld
but no one gave a proper answer. code...

What is the best way to flip a label on a button vertically or rotate it. If there's no way how can we flip the whole View, Button, TextView etc?

I have the Button defined as follows:
CODE:..........
The problem is that 'drawableTop' image is aligned to the top border of the Button view. I would like to center it (together with text label) vertically on the button. 'android:gravity' seems to work only on text label. It does not affect 'drawableTop' positioning.
I was able to center it vertically using 'android:paddingTop' - but that does not seem to be a good idea. I guess it would not work properly on different screen resolution/size.

I recently struggled with an apparently simple Android layout: I wanted a WebView above a Button. It worked fine with the following parameters:
WebView:
Height: wrap-content
Weight: unset (by the way, what is the default?)
Button:
Height: wrap-content
Weight: unset
However if the web page became too big it spilled out over the button. I tried various combinations of weights and heights, and all except one either completely hide the button, or partially cover it...............

I've put an EditText and Button into a horizontal LinearLayout but unfortunately the button is not aligned with the text field. In the Hierarchy Viewer the text field has a absolute_y of 30 while the button has 32. Please see screenshots of the Hierarchy Viewer here: http://picasaweb.google.com/sj1981/Android
The XML looks like this:...................

I am trying to make a button programmable way (no attributes on LinearLayout). In other words, button count on the View is dynamically.

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg

I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.
anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.
screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

I created a basic options menu, here an example of creating an element of me menu: menu.add(0, MENU_BACKWARD, 0, "").setIcon(R.drawable.btn_backward);
As you can see I don't want to show any text in this menu, just an icon ! But when the menu is showed, there is a "ugly" blank under the icon (the text is supposed to be there) and I want to avoid this. A least if it's possible to center the icon the options menus, it will be great.

I am writing to a canvas from a thread.
public void draw(Canvas canvas) {
Paint p = new Paint();
p.setAntiAlias(true);
p.setTextSize(30);
p.setColor(Color.WHITE);
p.setTextAlign(Paint.Align.CENTER);
canvas.drawText("Centered", xCentre, yCentre, p);
}
My problem start when I have a multi colored SpannableStringBuilder which I want to write to the canvas, and I have no idea how to do this. SpannableStringBuilder has a drawText() method which I have been unable to use. Or is there some other method to write a string to a canvas where some of the letters have a different color?

Any widget that will display a moving google map with my current location centered? There are a couple apps I've found that are close, they just don't update in realtime. The reason I ask is because I have my 7" galaxy tab mounted in my truck. I use a program called torque to add gauge widgets (coolant temp,boost pressure, rpm,etc) to my home screen and would like to have a moving map display as well. I understand this would be a battery hog,but the tablet is always plugged in.

As i am facing limitation of layout depth in my application, i am replacing some LinearLayout with RelativeLayout. However i am stopped by a supposely very simple issue (but apparantly without clean solution regarding that http://stackoverflow.com/questions/1499555/android-layout-centering-i..., nor in the ApiDemos sample where RelativeLayout are too simple):
How can i align vertically 3 items (in a simple way!) which are on a horizontal line with RelativeLayout without?
does not seem to have any effect at all.
Here is the xml; in this example i would like an icon at left (fixed width), a text label in the middle (fixed width) and an edit text on the right (remaining space). the problem is that the TextView seems to ignore the parameter android:layout_gravity="center_vertical", and seems to be top aligned with parent. code...
Of course i can use marginTop/Bottom and alignTop/Bottom on each single item but that's not very clean.

Lets say you have a normal textview, with "Stackoverflow" written in it, I would like to know if it it possible to rotate the textview about -90°, to have the S at the bottom and the W at the top of the screen?
of course, i could write my text in an image, rotate it and use it that way, but im interested in text right now.

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"/>

I have a WebView widget in my app that displays custom HTML content.The code is really simple - the class that handles the layout also implements the WebViewClient methods. It loads the html data into the WebView. The app works well on all OS's except Froyo. On Froyo the WebView doesn't respond to vertical scroll event it can scroll horizontally though.I had a onFling event listener - which has been disabled, but still no luck.

The row of my listview has 3 texts. What I want to do is to align all the rows texts vertically. I tried that using the TableLayout view for the row, and I've set the width for the first and third cell's as a constant. I'm not very happy using constants because of the porting issues. Is it possible to align these texts without in another way? Here is the layout...

I was wondering if there is a way for placing a view to the right side of another view and centering it vertically on the second views height. In know this can be done using a LinearLayout, but for other reasons the 2 views must be part of the same RelativeLayout.

My layout design is a TextView with long text and a ImageView to the right of the TextView. I want to center the ImageView in its parent vertically, so I used android:layout_centerVertical="true", but it turned out that the ImageView was aligned to the bottom of its parent. If I don't use layout_centerVertical property, the ImageView will be aligned to the top of its parent. How can I solve this problem? code...
