How would one go about drawing a shape, then adding multiple elements to it?
At first I thought I should make use of either a textview, or a button, then simply apply a rectangle as a background. The problem with that is my text is all the same size.
I would also like to eventually add an image to the below purple button.
My end result should look like this:
What would be very nice, is if there was some sort of container that one could use... unfortunately I am new to android, so I do not know what to search for.
Just use a LinearLayout and put two TextViews in it:
<LinearLayout
android:orientation="vertical"
android:height="wrap_content"
android:width="wrap_content"
android:padding="20dp">
<TextView
android:text="123,150"
android:width="wrap_content"
android:height="wrap_content" />
<TextView
android:text="TOTAL PAGE VIEWS"
android:width="wrap_content"
android:height="wrap_content" />
</LinearLayout>
This is an untested example to give you something to start with, you'll have to adjust font size/color and background yourself.
you should look for a layout combinaison :
FrameLayout to have layout superposition
RelativeLayout to position items

I am trying to create a table/grid for some items within my app and I would like to have a border around each cell to divide the items up and have a coherent association of the setting with the item. This app will be used in an industrial setting where there may be people unfamiliar with Android that need to use this, thus trying to make it as easy as possible.
The table/grid will contain TextView, EditText, Spinner, and Button, and will also be scrollable (via ScrollView parent).
I read about the GridView and found that it (seems) to only be able to get items programmatically, please correct me if I am wrong. I felt that this was unnecessary since I know what items I want and where. Also, I have not tried adding items to a layout programmatically yet so I figured I would try the other options first. Also, the GridView documentation does not say one way or the other if border lines are automatically shown, or if you can have them shown at all.
I started with a TableLayout and was able to get everything except the border lines to work. I tried android:divider to get the lines but that didn't work. One thought I had was to create a bunch of TextViews with black backgrounds and ~2dp widths/heights to make my own border lines. This feels like a huge waste though. Then I also read the TableLayout documentation and found this: "TableLayout containers do not display border lines for their rows, columns, or cells."
I then tried the GridLayout and had the same results as the TableLayout. I tried padding and margins, neither worked. Also, the GridLayout documentation states: "The grid is composed of a set of infinitely thin lines that separate the viewing area into cells."
My questions are:
Is there an attirbute that I missed in TableLayout or GridLayout that will give me border lines via the xml?
If no, then will the GridView give me the lines I want?
Will I be able to add all the perviously mentioned items I want to the GridView?
I was actually able to achieve the desired look by setting the android:background="#000000" within the GridLayout view and then in the child items I set the android:background="#8CDD81" (just some green color) and combined with android:layout_margin="2dp" I was able to get the "grid" lines that I wanted. Thanks to CommonsWare though for getting me thinking in a new direction that turned into a solution.
EDIT:
This does not work quite as anticipated. You need the android:layout_alignLeft/Right which are only available via RelativeLayout in order to get just the right width on the child items. Haven't tested this yet using this idea, child items within RelativeLayout within GridLayout.
Is there an attirbute that I missed in TableLayout or GridLayout that will give me border lines via the xml?
No.
If no, then will the GridView give me the lines I want?
No.

Yes, though how well something like a Spinner will work, I can't say.
The simplest way, off the top of my head, to give you the lines you seek is to have each cell of the TableLayout or GridLayout be some container containing the widget(s) for that cell, where you give the container a background that is your line. A ShapeDrawable could be defined in XML for that background, which will be nicely resizeable based upon the actual requirements of the cell.
For future visiters this is how I did it with TableLayout:
table.xml
<TableLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#969696">
<!-- table heading -->
<TableRow>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name"
android:background="#d2d2d2"
android:layout_margin="1dp"
/>
<Button android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Address"
android:background="#d2d2d2"
android:layout_margin="1dp"
/>
</TableRow>
<!-- table data -->
<TableRow>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Ahtisham"
android:layout_margin="1dp"
android:background="#f1f1f1"
/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Kashmir"
android:layout_margin="1dp"
android:background="#f1f1f1"
/>
</TableRow>
</TableLayout>
I'm trying to achieve the following layout: a fixed width TextView aligned to the left of its parent, with the text inside it aligned to the right side of that TextView (that's why fixed width, can it be done other way?) and the rest of the parent is filled with a drawable (simple line). Like this:
It's a ListView containing 2 types of rows and the layout for the rows with lines is quite trivial - LinearLayout with TextView and ImageView (I can post the exact code later if needed). And I'm getting a warning that it could be replaced with a single TextView with compound drawable.
I'm all for optimization so I really tried to follow that advice. Unfortunately I wasn't able to get the same result - the line is either constrained to TextView's width or text is aligned to the right side of the ListItem, now to fixed position.
Am I missing something?
Edit: Apparently it is not actually possible and since there are some other complications (the drawable is now a level-list drawable, which is not always a line and sometimes it has a non-fixed height that I have to set) I will leave it as it is now - linear layout, containing one TextView and one ImageView.
I don't think that you're missing anything. The TextView compound drawable features are not very customizable and in general are not worth the time you spend trying to get them to look right. Some lint warnings are a little overzealous and premature.
The optimization that the lint refers to is something that is better attributed for a fixed size image. In your case, the line has to stretch the rest of the screen length and as such it is not something that can be done with a textview with compound drawable. This kind of lint warning is more of a suggestion rather than something that MUST be done and is detected by just checking for a linear layout with only a textview and an imageview rather than checking what would need to go in the image view. If you already have it working the way you did it I think you should leave it alone.
Your view create from this -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/time"
android:layout_width="#dimen/today_time_width"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:gravity="right"
android:layout_marginRight="5dp" />
<ImageView
android:layout_gravity="center"
android:id="#+id/border"
android:layout_width="match_parent"
android:layout_height="#dimen/today_current"
android:src="?attr/item_boundary" />
</LinearLayout>
There is no way to achive this using only standart TextView. If you really want to reduce view count you can create your custom TextView class, set layoutWidth to matchParent and draw line from text end to right border. But it's not worth to be doing. Some extra views won't slow your list.
I am not sure if you will be able to achieve what you really want to , but then you could change the linear layout in the link you posted to something like this:
<RelativeLayout
android:id="#+id/relTrial"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/txtTime"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:gravity="right"
android:text="12:45 AM"
android:layout_alignParentLeft="true"/>
<LinearLayout
android:id="#+id/lnrSep"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:gravity="bottom"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_centerVertical="true"
android:orientation="horizontal"
android:background="#android:color/darker_gray"
android:layout_toRightOf="#+id/txtTime"
android:layout_alignParentRight="true"></LinearLayout>
</RelativeLayout>
This way the time text will be right aligned although being at the left side, and the line will also be visible.
Hope that helps.
If I got you right, you want to add bottom border to list view item?
What about to try this:
android:drawableBottom="#drawable/line"
I want to draw an image on the left of an EditText. I don't want the image appear insde the EditText though.
I use this:
<EditText
android:id="#+id/firstNameTxt"
style="#style/UserInfoInputs"
android:drawablePadding="20dp"
android:drawableLeft="#drawable/first_name" >
</EditText>
It displays the image inside of the EditText. However I use this on TextView and it works fine:
<TextView
android:id="#+id/positionValue"
style="#style/userInfo"
android:drawableLeft="#drawable/position" />
How this can be done for an EditText?
try this
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/go_image"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="#drawable/icon"
/>
<EditText
android:id="#+id/url"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:lines="1"
android:layout_weight="1.0" />
</LinearLayout>
let me know if this works.
The difference between the two use-cases you describe are simple. There is no difference. With an EditText, there are lines that are easily discernible. With a TextView there is not. Try setting the background property of the textview, and you'll see that the drawable is, in fact, drawn on the left side, but still 'inside', the TextView.
The simplest way to accomplish your task (as described) is to utilize an ImageView. Depending on what ViewGroup (LinearLayout, RelativeLayout, etc) you're using, the code may be a bit different; so, update your question with the appropriate info and I'll make my answer a bit more specific.
I should note that, another method you could use is to create your own custom component, which is really very easy to do. See this article Custom Components | Android Developer, be sure to scroll down to the Compound Controls heading title "Compound Controls". This would be especially helpful when this is a 'common' format of controls that you'll use often (I.E. you have an image next to a TextView throughout your app).
That is because the background part of the EditText stretches behind the entire contents of the view, including the drawables.
If you are using a RelativeLayout you can just add a separate ImageView:
<ImageView
layout_width="wrap_content"
layout_height="wrap_content"
layout_toLeftOf="#+id/firstNameTxt"
src="#drawable/first_name"
other imageview attributes as neccessary...
/>
<EditText
android:id="#+id/firstNameTxt"
style="#style/UserInfoInputs"
/>
Or if you use another kind of layout, create a LinearLayout-wrapper:
<LinearLayout
layout_width="wrap_content"
layout_height="wrap_content">
<ImageView
layout_width="wrap_content"
layout_height="wrap_content"
layout_toLeftOf="#+id/firstNameTxt"
src="#drawable/first_name"
other imageview attributes as neccessary...
/>
<EditText
android:id="#+id/firstNameTxt"
style="#style/UserInfoInputs"
/>
</LinearLayout>
I am trying to port my WP7 app to android.
Does anyone know how I can layout the text on a single button so that some text appears aligned left and other text appears aligned right? (See below). I need access to be able to dynamically change the percentage number on the right side using code but the text on the right is just static.
Anyone know the answer to this?
The image is here:

Yes you could make it two buttons.
Remove all padding and margin from between them.
Set the same background drawable.
And just ensure when the left is clicked it invokes the right's onPress method (so it looks as if they depress together).
Or wrap the buttons/imageviews/textviews in a layout and perform the onClick on that.
I would use a RelativeLayout for this.
<RelativeLayout
android:width="fill_parent"
android:height="wrap_content"
android:clickable="true"
android:background="#18a2e7"
android:padding="10dip">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Something" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_align_parentRight="true"
android:text="0%" />
</RelativeLayout>
I have a row of buttons with custom 9 patch images, and variable length text. I would like the buttons to be the same height. When the text is long enough to wrap, it expands the button size, making the button with wrapped text bigger than the others. I'm laying these buttons out in code in linear layouts. I can fix the size of the button, but then it just cuts off the bottom. How can I make the text take up more of the padding space of the button, so that the text butts up against the top line of the button?
9patch content area is just used to set a padding. If you change the button's padding you will override the one set by the 9patch.
edit
try something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button android:text="ButtonButton"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:paddingTop="0dp"
android:paddingBottom="10dp"/>
<Button android:layout_width="wrap_content" android:text="Button"
android:layout_height="match_parent"/>
<Button android:layout_width="wrap_content" android:text="Button"
android:layout_height="match_parent"/>
</LinearLayout>
this way the button will be as high as the others. Sadly, I don't know if it depends on the original button's 9patch that might have asymmetrical paddings, but I can't make the text align with that from other buttons (I think gravity is by default set to center). Maybe with your 9patch it works though. (EDIT: oh, but if you'll have two lines of text who cares about alignment)
Ultimately I was unable to find a nice way of doing this without creating a custom view class.
