TextView and EditText overflow

I've got a need to display and TextView (label), EditText(Input) and TextView(suffix) in a line.
The issue I have is - if the label TextView is too long it The EditText and Suffix TextView and not drawn.
Here's my code.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_weight="0"
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.." />
<TextView
android:padding="5dp"
android:layout_weight="0"
android:text="Suffix.."
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
So what I want is - even if the label is over 2-3 lines, for an EditText to appear followed by another TextView.
Any pointers would be appreciated.
Thanks!
Edit:
I've added some 'diagrams' so you can understand what I want to do a bit better.
The label to the EditText can be arbitrary length(2/3 lines), so whenever the label finishes I want an EditText to start (which is followed by another TextView showing a suffix..)
..
![This shows a 2 line label and TextView..]
Edit 2: Thanks for the responses guys!! I think #questioner has really understood what I want to do i.e. I want your 3 views to move to other lines so that they behave like they were one view - and as he has suggested i'll have to find a library for this!

How about this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:padding="5dp"
android:text="Label"
android:id="#+id/label_text_view"
android:layout_width="100dp"
android:layout_gravity="center_vertical"
android:layout_height="wrap_content"/>
<EditText
android:layout_weight="1"
android:id="#+id/input_edit_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textColorHint="#color/dark_grey"
android:textColor="#color/black"
android:hint="text.."/>
<TextView
android:padding="5dp"
android:text="Suffix.."
android:layout_gravity="center_vertical"
android:background="#color/lite_grey"
android:id="#+id/suffix_text_view"
android:layout_width="100dp"
android:layout_height="wrap_content"/>
</LinearLayout>
If you want your 3 views to move to other lines so that they behave like they were one view - you should use external library for that.

Why not use a RelativeLayout instead of LinearLayout and then use android:layout_below="#+id/..." or android:layout_above="#+id/..." also android:layout_toRightOf="#+id/..." or android:layout_toLeftOf="#+id/..."

Set
android:layout_weight="1"
for each view so that they all occupy the same amount of horizontal space.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="1">

Button size and padding within RelativeLayout

I'm attempting to create a a Heading + button similar to the Google Music App, e.g. where there is a "Songs" Header on the Left and then on the right there is a Button with the text "X more"..
I've using a RelativeLayout for the TextView and Button
My problem is that the button is taking up the size of the layout that contains the text the height is all wrong and the padding doesn't seem to do anything.
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
[REMOVED for clarity]
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/list_foreground"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:text="#string/photos"
android:textAppearance="?android:attr/textAppearanceMedium" />
<Button
android:id="#+id/photo_button"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:background="#color/actionbar_background"
android:padding="10dp"
android:text="test" />
</RelativeLayout>
What am I doing wrong here?

RelativeLayouts are designed to have children in the layout "relative" to each other. In other words, if you want the Button to the right of the Textview, you need to tell it.
Because you are aligning relative to the parent LEFT / RIGHT, it appears that things are "kind of" working.
You may be better off with a LinearLayout, depending on your needs. LinearLayouts use "orientation" not RelativeLayouts.
You should look over some tutorials (like this one: http://mobile.tutsplus.com/tutorials/android/android-layout/) but ultimately you will probably put your button in first and then your text view so that the textview content will wrap appropriately.

To get the same effect as the Music App I ended up using a RelativeLayout but instead of a Button I'm using another TextView, this is giving the impression it's a button but it gives me more scope to format the background etc. I think just setup a OnClickListener in the code
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/photo_title">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="10dp"
android:text="#string/photos"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/more_photo_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:background="#color/actionbar_background"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:text="10 MORE"
android:textColor="#color/button_text"
android:textSize="12sp" />
</RelativeLayout>

Center multiple items in a RelativeLayout without putting them in a container?

I have a RelativeLayout containing a pair of side-by-side buttons, which I want to be centered within the layout. I could just put the buttons in a LinearLayout and center that in the RelativeLayout, but I want to keep my xml as clean as possible.
Here's what I tried, this just puts the "apply" button in the center and the "undo" button to the left of it:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15sp">
<TextView
android:id="#+id/instructions"
android:text="#string/instructions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="15sp"
android:layout_centerHorizontal="true"
/>
<Button
android:id="#+id/apply"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/apply"
android:textSize="20sp"
android:layout_below="#id/instructions"
/>
<Button
android:id="#+id/undo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/undo"
android:textSize="20sp"
android:layout_toLeftOf="#id/apply"
android:layout_below="#id/instructions"
/>
</RelativeLayout>

android:gravity will align the content inside the view or layout it is used on.
android:layout_gravity will align the view or layout inside of his parent.
So adding
android:gravity="center"
to your RelativeLayout should do the trick...
Like this:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_marginTop="15sp">
</RelativeLayout>

Here is an extension of BrainCrash's answer. It is a non nested option that groups and centers all three horizontally and vertically. In addition, it takes the top TextView and centers it horizontally across both buttons. If desired, you can then center the text within the TextView with android:gravity="center". I also removed the margins, added color, and set the RelativeLayout height to fill_parent to highlight the layout. Tested on API 11.
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:background="#android:color/black"
>
<TextView
android:id="#+id/instructions"
android:text="TEST"
android:textSize="20sp"
android:background="#android:color/darker_gray"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignLeft="#+id/undo"
android:layout_alignRight="#+id/apply"
android:gravity="center"
/>
<Button
android:id="#+id/apply"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="APPLY"
android:textSize="20sp"
android:layout_below="#id/instructions"
/>
<Button
android:id="#+id/undo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="UNDO"
android:textSize="20sp"
android:layout_toLeftOf="#id/apply"
android:layout_below="#id/instructions"
/>
</RelativeLayout>

android:layout_gravity="center"
will almost give what you're looking for.

Here is a combination of the above answer's that solved my specific situation:
Centering two separate labels within a layout that also includes a button in the left most position of the same layout (button, label, label, from left to right, where the labels are centered relative to the layout containing all three views - that is, the button doesn't push the labels off center).
I solved this by nesting two RelativeLayout's, where the outer most layout included the
Button and an Inner-RelativeLayout.
The Inner-RelativeLayout contained the two text labels (TextView's).
Here is a snippet that provides the details of how the centering and other layout stuff was done:
see: RelativeLayout Gravity not applied? and
Gravity and layout_gravity on Android
for the difference's between gravity and layout_gravity.
Tweak the paddingLeft on the btn_button1 Button to see that the TextView's do not move.
(My apologies to havexz for the downvotes. I was too hasty in thinking that just b/c your suggestions didn't solve the exact question being ask, that they do help to solve very similar situations (the answer here solves a very specific situation, and only the combination of all these answer's solved my problem. I tried upvoting, but it won't let me unless I edit the answer's, which I don't want to do.)

LinearLayout is a good option. Other than that there are options like create an invisible view and center that and then align left button to the left it and right on the right of it. BUT those are just work arounds.

Indent bullet list in TextView

I have a TextView which I fill with text from a string resources in strings.xml. The string resource contains < li > elements to create a bullet list inside the TextView. My problem is that I want to control the indention of lines in the bullet list that span over more than one line. Default the text isn't indented past the bullet so it looks kind of ugly. Is it possible to do this with style parameters or to create bullets in some other way?
Thanks in advance.
edit:
Is it really answered? I don't have any problems producing the bullet list, as described in those links but I'm having problems getting the layout correct. The indentation is like this:
text that go beyond the width
of the line.
And I want the "of the line" to at least start indented as far as the text after the bullet. That's what I try to achieve.

I'm suprised that there seems to be noone with this problem. I mean, bullet list can't be that uncommon in about-dialogs, FAQ etc and a bullet doesn't have to contain too much text to span more than one row and run into this problem.
Anyway, I got to solve it like this for now:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:id="#+id/ScrollViewTipsLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TipsLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:layout_height="wrap_content"
android:id="#+id/TableLayout01"
android:layout_width="wrap_content"
>
<TableRow>
<TextView android:id="#+id/tvIngress"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#+string/tv_picking_content_ingress"
android:layout_span="2"
android:singleLine="false"
android:layout_weight="1"
/>
</TableRow>
<TableRow>
<TextView android:id="#+id/tvCleaningDot1"
android:layout_height="wrap_content"
android:text="•"
android:singleLine="false"
/>
<TextView android:id="#+id/tvCleaningFirst"
android:layout_height="wrap_content"
android:text="#+string/tv_picking_content_first"
android:layout_width="0dp"
android:layout_weight="1"
android:gravity="left"
android:singleLine="false"
/>
</TableRow>
<TextView android:id="#+id/tvCleaningDot2"
android:layout_height="wrap_content"
android:text="•"
android:singleLine="false"
/>
<TextView android:id="#+id/tvCleaningSecond"
android:layout_height="wrap_content"
android:text="#+string/tv_picking_content_second"
android:layout_width="0dp"
android:layout_weight="1"
android:gravity="left"
android:singleLine="false"
/>
</TableRow>
</TableLayout>
</RelativeLayout>
I use it to present static text in a bullet list so I don't bother to create the bullet + text dynamically in code. If anyone have any suggestion how to accomplish the same thing in a better way, please enlight me.
Btw, if going with the solution suggested in second link above:
android:text="<ol><li>item 1\n</li><li>item 2\n</li></ol>
The second, third etc. row in a bullet that span over more than one row won't get same indention as first line, which is quite ugly.

Thank you #Bjorn
You can also do something like bellow.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/point"
android:textAppearance="?android:attr/textAppearanceSmall"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Text Here"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textSize="14sp" />
</LinearLayout>

The way I solved this problem was by using a RelativeLayout and marginLeft. The marginLeft will put a blank margin between it and the previous item.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbarTrackVertical="#drawable/scrollbar_vertical_track"
android:scrollbarThumbVertical="#drawable/scrollbar_vertical_thumb"
android:scrollbarSize="12dip">
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10sp">
<TextView
android:id="#+id/body_text3"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="Main paragraph of text, before the bulleted list"
android:textSize="15sp" />
<TextView
android:id="#+id/type1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="• First bullet"
android:textSize="15sp"
android:layout_below="#+id/body_text3"
android:layout_marginLeft="25dp" />
<TextView
android:id="#+id/type2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lineSpacingExtra="3sp"
android:text="• Second bullet"
android:textSize="15sp"
android:layout_below="#+id/type1"
android:layout_marginLeft="25dp" />
</RelativeLayout>
</ScrollView>

Just trying to point out the key answer of the question:
to create an bullet list, use TableLayout with two columns for each row. One column for TextView of a bullet and the other one for the text
to make text TextView fill the rest empty TableRow and indented at new line, set the weight to 1. You can set the bullet weight to zero or just simply not set the bullet weight and let it empty
based on my experience, changing width parameter do not affect the text and the bullet. So you can leave it empty or set it to anything you want.
Example:
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/bullet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/bullet"/>
<TextView
android:id="#+id/TextView01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="this is the text of a bullet list"/>
</TableRow>
</TableLayout>

How to create column-like layout for ListView rows?

I have a relative layout which looks like this:
Here is the code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/nameText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_alignParentLeft="true"
android:text="Symbol"
/>
<TextView
android:id="#+id/priceText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_toRightOf="#+id/nameText"
android:gravity="right"
android:text="100"
/>
<TextView
android:id="#+id/changeText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:layout_toRightOf="#+id/priceText"
android:gravity="right"
android:text="1.3"
/>
</RelativeLayout>
How can I get the company name to line up next to the number 1.3?

Following up on Mayra's answer, here's one way to do it using layout_weight:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TableRow>
<TextView
android:id="#+id/left_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left|center_vertical"
android:padding="5dip"
android:layout_weight="0"
android:text="Code"
/>
<TextView
android:id="#+id/middle_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right|center_vertical"
android:padding="5dip"
android:layout_weight="1"
android:text="Name of Company"
/>
<TextView
android:id="#+id/right_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"
android:gravity="right|center_vertical"
android:layout_weight="0"
android:text="1.3"
/>
</TableRow>
</TableLayout>

It's not clear exactly what you want to have happen, but here are a few options:
If you want columns to be aligned across rows, you might consider using a TableLayout.
You can also use the "weight" atribute to affect what percentage of the screen each TextView takes up. If you assign a value of 1 on the left-most text view, and 0 on the other 2, this will cause the left text view to take up all the extra space, and thus push the middle text view to the right. This will probably cause the middle text view to look right aligned though. You could instead give the left one 20%, the middle one 50% and the right one 30% by assign 2, 5 and 3.
You could also just set an explicit size for the text views (in dpi), but this might be problamatic with different sized screens.

I agree with Mayra! Use the TableView, you'll get the formatting your looking for as well as keep almost all functionality of a ListView (scolling, and list oriented functionality)
