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>

I am aiming for a layout similar to the native calculator app. I want text to trail off the left of the screen without moving the buttons on the right. Currently my text moves to the left until filling the screen at which point the buttons are pushed off the right edge.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:layout_weight="1"
android:gravity="right"
android:orientation="horizontal" >
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="none" >
<TextView
android:id="#+id/display_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:textColor="#android:color/white"
android:textIsSelectable="true"
android:textSize="30sp" />
</HorizontalScrollView>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:id="#+id/delete_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onDelete"
android:text="#string/delete_button" />
<Button
android:id="#+id/equate_button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:onClick="onEquate"
android:text="#string/equate_button" />
</LinearLayout>
</LinearLayout>
You don't need to put your TextView into a HorizontalScrollView, it will automatically become scrollable when the text exceeds the bounds. See docs: http://developer.android.com/reference/android/widget/TextView.html#attr_android:scrollHorizontally
Just add android:scrollHorizontally="true" to the TextView in the layout.
You may also need to change the text view's layout_weight to 0 or set its layout_width to something fixed (like 100dp).
To get the text to go right-to-left, set the gravity on the TextView to be android:gravity="right|center_vertical"
I also humbly refer you the source of the calculator app you are trying to emulate: https://github.com/android/platform_packages_apps_calculator/tree/master/src
I'm trying to set my TextView to the left of an ImageButton, but I can't seems to find this option.
I was expecting to use something like android:layout_alignLeft, but this option is missing.
I've tried to google the issue, but couldn't find any relative results.
Without it my TextView overlaps the ImageButton and I want to avoid it.
UPDATE
The full xml code is too complex, but here is the important part of it:
<FrameLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentLeft="true"
android:background="#color/white"
android:layout_marginLeft="8dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
android:layout_toLeftOf="#+id/frameLayoutBalanceClosed">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/button_edit_nickname"
android:id="#+id/card_closed_control_editNickname" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/card_closed_description_nickname"
android:layout_margin="8dp" android:layout_gravity="left"/>
</FrameLayout>
I think what you need is a RelativeLayout. You can specify your TextView to the left of your ImageView with it's specifications. Your code would look something like this:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/imagebutton1" />
<ImageButton
android:id="#+id/imagebutton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
The reason FrameLayout isn't working is because it's purpose is to overlay items on top of each other, which wouldn't work at all!
If that isn't what you're looking for, you could also use a TableLayout in which items are arranged in columns.
I have two custom RadioButtons side by side that fill the width of the screen. I want to have text and an image to the right of the text, centered in the button.
drawableRight draws the image way off to the right of the button, not near the text. I can't use drawableEnd because I don't have Android 4.0
I've tried using a Spannable, but the problem with that is that the image is bigger than the text. I don't want it aligned with the bottom or baseline of the text; I want it to be centered in the button on its own.
The best solution I've found is making a clickable RelativeLayout with a TextView and ImageView centered in it. This makes the button look the way I want it to, but it seems like a lot of work to do that, and to program each RelativeLayout to act like a RadioButton in a RadioGroup.
Is there an easier way, or something that I'm missing? Or should I keep my RelativeLayout idea? Here's my xml for this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RelativeLayout
android:id="#+id/first_relativelayout"
android:clickable="true"
android:background="#drawable/radio_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/first_textview"
android:text="#string/first_radiobutton_label"
android:textAppearance="?android:attr/textAppearanceButton"
android:textColor="#android:color/white"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></TextView>
<ImageView
android:contentDescription="#string/image_description"
android:id="#+id/first_imageview"
android:layout_centerVertical="true"
android:src="#drawable/it"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/first_textview">
</ImageView>
</RelativeLayout>
<RelativeLayout
android:id="#+id/second_relativelayout"
android:clickable="true"
android:background="#drawable/radio_button"
android:layout_weight="1"

android:textAppearance="?android:attr/textAppearanceButton"

I kept going with the RelativeLayout solution. It takes more work than it seems should be worth it, but it works perfectly.
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.
I'm pretty sure I've done this before, but I've forgotten how.
Here's the problem:
I've got a button and a textview, and I want the textview to be centered, while the button is on the left side.
No problem? Just put them in a relativelayout, make the textview centerinparent, and the button alignparentleft.
But now I'm going to dynamically change the text, so it can potentially be written on top of the button! I'll just add toRightOf="#id/button" on the textview. No, now it's no longer centered.
I wish I could provide a screenshot, but it seems the computer is out of memory and can't do that.
Here's some code: http://pastebin.com/3N70Vjre (Since I can't paste xml...?)
<RelativeLayout
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:text="text!"
/>
<TextView
android:id="#+id/toptext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:layout_toRightOf="#id/leftbutton"
android:layout_centerInParent="true"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
</RelativeLayout>
Try this (unfortunately I'm at work so can't jump into Eclipse to get you some code) -
Change the layout_width of the TextView to fill_parent.
Set the gravity of the TextView to center (so the text centers inside the TextView)
Set the layout_weight of the Button to 1 and the layout_weight of the TextView to 2. Note that you may have to fudge with these numbers to get the layout you're looking for.
This should center the text of the TextView after the Button, though it will not center the TextView itself. You can accomplish that by replacing the TextView with a container (Linear/Relative Layout) and doing the same method as above on the Layout instead of the TextView. You would then put your TextView inside the container and set the container's gravity to "center".
Hope this helps point you in the right direction :)
You can try this (pseudo-code):
<RelativeLayout>
<Button>
<LinearLayout toLeftOf="toptext" type="horizontal">
<TextView gravity="center">
</LinearLayout>
</RelativeLayout>
You might have to have the LinearLayout as width="fill_parent". Not sure if that will work nor not. You can subsequently try some of the things listed here: http://thinkandroid.wordpress.com/2010/01/14/how-to-position-views-properly-in-layouts/
Try declaring the TextView first, then aligning the button to the left of the text view. Keep in mind you may run into issues if the TextView becomes too wide.
EDIT: I see, so you're trying to do something sort of like the iPhone's header with back/next buttons (similar anyway). Try this modification. I still believe you're going to run into issues if the TextView gets large enough to hit the Button, though.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
>
<TextView
android:id="#+id/toptext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:layout_alignParentCenter="true"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="text!"
/>
</RelativeLayout>
Try this FrameLayout instead. This may do more what you're expecting:
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/toptext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#android:color/white"
android:textSize="16sp"
android:textStyle="bold"
android:text="Text!"
android:singleLine="true"
/>
<Button
android:id="#+id/leftbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text!"
/>
</FrameLayout>
