How to set textView as right as possible and set textView show only a part of text?

I have the xml code shown below. Everything is working as it should except the final textView( id locationTextView) which won't stay right. I want it to stay as right as possible, but I can't do that(it still appears straight after the linear Layout).Should I set a left margin?. And for the textView1 how can I make it to show only a certain part of the whole text, because I have texts of different lengths and they ruin the layout.
<?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="wrap_content"

Try android:layout_weight="1" or some other value for your locationTextView. You can also try out android:weightSum="3" (or that is appropriate instead of 3) on your root LinearLayout. Assign proper weights to your different child views. You can get help here
For showing text in a presentable way, you could use android:ellipsize="marquee" or other options available.

Put a textview over Imageview in LinearLayout

I have stuck in some xml code and i hope you can help me out.
So here is what I need/what I have done by now.
I have 3 images of 650px width and I need them one below another while keeping aspect ratio.
I did that with the following code and it looks as it should. No problem here.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ll"
android:orientation="vertical"
android:background="#3afa3f"
android:weightSum="3">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/krk_history"
android:layout_weight="1"
android:background="#drawable/povjestkrka_vintage_yellow600" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/krk_frankopan"
android:background="#drawable/frankopan2_vintage_sundown600" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/krk_turizam"
android:background="#drawable/krk_turizam_vintage"/>
The problem is. I need to put three textviews in a left bottom corner of each image. Imagine it like image menu with text description on each image.
So, I can not use relative or frame layout because images won't play nicely with each other :) There is always a gap between or not aspect ration etc. I need weightsum.
Second, I can't hardcode the text on each image in photoshop because the app will be translated and text needs to change for each language.
I can have different images for each language but I am trying to avoid that.
Ah yea, one more last thing.
I tried to put entire linearlayout in relative layout and put the text between but the text appears beneath the image and I can't bring it upfront.
Any suggestions?
Thanks a lot,
Xsonz

just copy 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="match_parent"

android:layout_weight="1">

</FrameLayout>

Take three FrameLayout inside your LinearLayout and inside FrameLayout keep the ImageView and TextView.
Or Else You can use RelativeLayout and give dependency to Views

You can use frame layout inside linear layout. create imageview inside the linear layout and create textview in another frame layout below it.
<FrameLayout
android:id="#+id/frameLayout_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/krk_history"
android:layout_weight="1"
android:background="#drawable/povjestkrka_vintage_yellow600" />
</FrameLayout>
<FrameLayout
android:id="#+id/frameLayout_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="-5dp" >
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="string" />
</FrameLayout>

Something like this might work for you.
//your layout -> LinearLayout>
....
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/image1"
android:layout_weight="1"
android:background="#drawable/A1" />
<TextView android:id="#+id/textview1"
android:layout_margin="0dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Text"
android:layout_below="#id/image1"
android:layout_alignLeft="#id/image1" />
</RelativeLayout>
// end your LinearLayout
You can play with these parameters using Relative Layout Parameters android.com. The relative layout allows you to control the "relative" positioning between your elements.
You can lay your images out side by side, or in whatever fashion you wish.
Then you can adjust the text dynamically.

Problems with LinearLayout, views aren't resembling the preview in Graphical Layout on device

So I'm having a problem that is driving me crazy. Knowing the purpose of my app isn't important/relevant so I'll just paste my code from the xml file. The layout is a RelativeLayout, but the problem I'm having is inside of this LinearLayout.
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/background_orange"
android:id="#+id/rel_layout" >
<RelativeLayout
android:id="#+id/layout_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="false"
android:layout_centerHorizontal="true">
<ImageView
android:id="#+id/component_1"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:src="#drawable/source1"
/>
<ImageView
android:id="#+id/component_2"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_above="#id/component_1"
android:src="#drawable/source2"
android:layout_alignRight="#id/component_1"
android:layout_marginRight="-50dip"
android:layout_marginBottom="-25dip"
/>
</RelativeLayout>
<LinearLayout
android:id="#+id/problemIsHere"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:orientation="horizontal"
>
<EditText
android:id="#+id/edit_text"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"
android:hint="What&apos;s your question?"
android:imeOptions="actionDone"
android:inputType="textCapSentences|textAutoComplete"
android:textSize="25sp"
android:layout_gravity="left"
android:textStyle="bold" />
<ImageButton
android:id="#+id/image_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dip"
android:layout_weight="0"
android:layout_gravity="right"
android:background="#drawable/source3"
/>
</LinearLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/problemIsHere"
android:gravity="center"
>
<ImageView
android:id="#+id/image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/source4"
android:onClick="computeUserInput" />
<ImageButton
android:id="#+id/image_button0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/image_view"
android:layout_alignTop="#id/image_view"
android:layout_marginLeft="-2dip"
android:background="#drawable/voice_recognition_touse"
/>
</RelativeLayout>
Again, this is nested inside of the parent, RelativeLayout. In the preview, when clicking on the "Graphical Layout" tab, this looks like exactly what I want; EditText to the left of a small ImageButton, with correct proportions and margins. However, when I run this on my device, the LinearLayout is REVERSED, meaning now that the EditText is to the RIGHT of the ImageButton. The proportions and margins are still accurate though. Does anyone know what is going wrong here?
Note: I've already cleaned and refreshed my project; this was ineffective. I've also tried removing the layout_gravity attributes, and that did nothing.
Thanks

RelativeLayout: align View centered horizontal or vertical relative to other view

Is it possible to align a view in XML in a RelativeLayout centered horizontal or vertical according another already existing view.
For example: lets say there is something like this:
The second text view should be displayed centered below the first text view:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="72dp"
android:text="dynamic text" />
<TextView
android:id="#+id/second"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/textView"
android:layout_marginLeft="43dp" <!-- Is there a rule to center it? -->
android:text="centered below text 1" />
</RelativeLayout>
Is is possible to implement something like that in XML? Is there a rule that i have missed yet? I do not want to calculate the position programmatically

I have a much better solution than the accepted one. NO EXTRA NESTING! You can do this by combining two attributes on the smaller view. if you are centering horizontally you can use both align_start & align_end to the bigger view. Make sure the text gravity is centered btw "android:gravity="center". For Vertical alignment use both align_top & align_bottom. below is the modified implementation of your layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="43dp" >
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignStart="#+id/second"
android:layout_alignEnd="#+id/second"
android:gravity="center"
android:text="dynamic text" />
<TextView
android:id="#+id/second"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/textView"
android:gravity="center"
android:text="centered below text 1" />
</RelativeLayout>
No need for unnecessary nesting like the accepted answer.

Use a separate parent layout for those views and add it in your main layout(can contain other things if you have)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center"
android:layout_marginLeft = "30dp">
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="dynamic text" />
<TextView
android:id="#+id/second"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="centered below text 1" />
</LinearLayout>
...
...
other veiws go here
...
</RelativeLayout>

Use the followings which suits you
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:layout_centerVertical="true"

Correct solution is to use ConstraintLayout
I tried to align a textview horizontally below a button in a RelativeLayout but it was not possible as align_bottom and layout_below didn't play well together. Finally i picked up constraintLayout and tried the same logic and it worked like a charm. here is the code below.
<android.support.constraint.ConstraintLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipChildren="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<Button
android:id="#+id/episode_recording_header_stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.399" />
<TextView
android:id="#+id/button_selected_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:textAlignment="center"
android:textColor="#android:color/black"
android:textSize="12sp"
android:text="text which is exactly center aligned w.r.t the Button above"
app:layout_constraintEnd_toEndOf="#+id/episode_recording_header_stop"
app:layout_constraintStart_toStartOf="#+id/episode_recording_header_stop"
app:layout_constraintTop_toBottomOf="#+id/episode_recording_header_stop"
/>
</android.support.constraint.ConstraintLayout>
The final output is attached below

Do this->
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="dynamic text" />
<TextView
android:id="#+id/second"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView"
android:layout_centerHorizontal="true" <!-- Is there a rule to center it? -->
android:text="centered below text 1" />
</RelativeLayout>

I found the solution:
Wrap the content into another RelativeLayout and then you can place this LayoutWrapper wherever you want:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="58dp"
android:layout_marginTop="58dp" >
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerInParent="true"
android:text="dynamic text" />
<TextView
android:id="#+id/second"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView"
android:layout_centerInParent="true"
android:text="centered below text 1" />
</RelativeLayout>
</RelativeLayout>

If you need to use RelativeLayout please don't use the nested layouts as far as possible. Today we have many other efficient cases to solve your task. But with use of the old faithful RelativeLayout the better way is to use attributes android:layout_alignTop, android:layout_alignBottom and android:gravity. For example, you would like to align TextView according to EditText vertically.
<RelativeLayout ...>
...
<TextView
android:id="#+id/tv1"
...
android:gravity="center"
android:layout_alignTop="#+id/edt1"
android:layout_alignBottom="#id/edt1"/>
<EditText
android:id="#+id/edt1"
...
android:layout_toRightOf="#id/tv1"/>
</RelativeLayout>
In the same way you can use android:layout_alignLeft, android:layout_alignRight and android:gravity or android:layout_alignStart, android:layout_alignEnd and android:gravity horizontally.

MergeAdapter layout issue in a fragment

I'm trying to make a layout in Android with Fragments. I started to use Commonsware's MergeAdapter but I'm having a weird bit of trouble. The layout worked fine before, but now I get this:
http://img856.imageshack.us/img856/2796/layoutbug.png
There are a couple problems: The white strip should have text going all the way across its length. I set the TextView with a white background to make sure the width was being set correctly. The checkbox right below it should also say "Issue?" but it's trying to wrap the text for some reason.
Here is the layout code that is being added:
<?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="match_parent" android:orientation="vertical">
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Instructions" />
<TextView android:id="#+id/tvInstructions" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Instructions go here" android:textSize="32dp" android:background="#FFFFFF"></TextView>
<LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="horizontal" android:paddingTop="24dp">
<CheckBox android:id="#+id/cbIssues" android:layout_height="wrap_content" android:layout_weight="1" android:layout_width="0dp" android:text="Issues?" />
<TextView android:id="#+id/tvStation" android:layout_height="wrap_content" android:layout_width="0dp" android:layout_weight=".5" android:text="Station:" />
<Spinner android:id="#+id/spStation" android:layout_height="wrap_content" android:layout_width="0dp" android:layout_weight=".5"/>
</LinearLayout>
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Pending data" />
</LinearLayout>
and here's how I'm inflating it inside the Fragment's onActivityCreated:
LayoutInflater inflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
MergeAdapter _adapter = new MergeAdapter();
View observationHeaderView = inflater.inflate(R.layout.observationheader, getListView(), false);
_adapter.addView(observationHeaderView);
I get a feeling it has something to do with how I'm inflating the layout. Any help would be appreciated. Thanks.

Don't use match_parent for android:layout_height for something going into an AdapterView, such as your root LinearLayout.
You might also consider temporarily putting your header layout outside the ListView (e.g., in a vertical LinearLayout also holding the ListView) and get it debugged before adding the complication of having it in the ListView.
Beyond that, fire up Hierarchy View (Eclipse perspective or standalone edition) and try to figure out where your layout rules are going wrong.
Also, I am uncertain how well your Spinners will work inside of a ListView on Honeycomb.

It appears my problem was with layout_width being match_parent in certain places in my header, when it should have been wrap_content. The following worked:
<?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="match_parent" android:orientation="vertical">
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Instructions" />
<TextView android:id="#+id/tvInstructions" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Instructions go here" android:textSize="32dp" android:background="#FFFFFF"></TextView>
<LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="horizontal" android:paddingTop="24dp">
<CheckBox android:id="#+id/cbIssues" android:layout_height="wrap_content" android:layout_weight="1" android:layout_width="wrap_content" android:text="Issues?" />
<TextView android:id="#+id/tvStation" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_weight=".5" android:text="Station:" />
<Spinner android:id="#+id/spStation" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_weight=".5"/>
</LinearLayout>
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Pending data" />
</LinearLayout>
