Is there a way to layout a view inside a relativelayout next to a border.
I have the following layout(Reduced test case) and I would like to have the image moved as far to the right as possible, so it aligns with the right border. Is there any layout way to do that?
<RelativeLayout android:background="#ff0000"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText android:layout_width='200dp'
android:layout_height='wrap_content'
android:text='First line'
android:id='#+id/first' />
<ImageView android:src='#drawable/test_grid16x16'
android:layout_width="16dp"
android:layout_height="16dp"
android:layout_toRightOf ='#id/first'/>
</RelativeLayout>
In a RelativeLayout, childen can set these attributes to true to be aligned to their container's borders: alignParentTop, alignParentBottom, alignParentLeft, and alignParentRight; and can be combined.
In your case: add alignParentRight="true" to your ImageView.
I'd also move this:
android:layout_toRightOf ="#id/first"
to
android:layout_toLeftOf ="#id/myImage"
in you EditText instead of in your ImageView.
Because now your ImageView rules the scene, and the EditText must be placed accordingly (also, you have to declare the EditText AFTER the ImageView, or the ImageView's id still isn't assigned).
Let's say that now it is the EditText that has to be placed "near to" (toLeftOf) the ImageView, after the ImageView has been created and placed.
In other words, this is what you want:
<RelativeLayout
android:background="#ff0000"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:src="#drawable/test_grid16x16"
android:id="#+id/myImage"
android:layout_width="16dp"
android:layout_height="16dp"
android:alignParentRight="true"
/>
<EditText
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_toLeftOf ="#id/myImage"
android:text="First line"
android:id="#+id/first"
/>
</RelativeLayout>
Note that, here and there, you put a single quotation mark ('), instead of a doble quotation mark (").
Try this code-
<RelativeLayout android:background="#ff0000"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/myimg"
android:text="First line"
android:id="#+id/first" />
<ImageView android:id="#+id/myimg"
android:src="#drawable/test_grid16x16"
android:layout_width="16dp"
android:layout_height="16dp"
android:layout_alignParentRight="true"
/>
</RelativeLayout>
Hope this works.
Or In your code add- android:layout_alignParentRight="true" in ImageView.
And android:layout_alignParentLeft="true" in EditText.
Use " in android attributes instead of '

I am trying to have a TextView with an ImageView directly to its right. Right now the image partially overlaps the far right of the text, so if the text inputted is long, then the image is "over" the text. I have an ellipse setting on the text but I need the TextView to "stop" right at the left border of the ImageView.
TextView layout settings:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
ImageView layout settings:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
Try this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/iv"
android:singleLine="true"
android:maxLines="1"
android:ellipsize="end"
.... />
<!-- background == #null if you don't want default button background -->
<ImageButton
android:id="#id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_margin="3dp"
android:background="#null"
.... />
</RelativeLayout>
EDIT
See the comments in regards to why this works and the posted question doesn't. Also take a look at
Android Relative Layout alignParentRight and alignParentEnd
for a reference to end/right and start/left attributes.
I am trying to put a text below an image but they are not showing up in android layout.
Here is the screenshot:
I dont' see any text below image.
And my code: inside a relative layout

Not sure what is wrong?
Assuming you follow Googles Design guidelines
(Tabs with icons and text Height - 72dp;
Icon - 24 x 24dp)
Change 'match_parent' to 'wrap_content' for the ImageViews
The problem is you have put android:layout_height="match_parent" for image views and android:layout_height="wrap_content" for text views. Either use wrap_content for image view or use use a LinearLayout with android:weight property. Using LinearLayout would also solve your problem of alignment if it occurs!
Try setting android:layout_alignParentBottom="true" instead of android:layout_below="#+id/homeicon".
This aligns the text at the bottom of the parent. You might also need to set android:layout_alignLeft="" and align it to the corresponding imageView.
This method will only work, if there is enough padding below the image. This is because the text will now overlap the image.
EDIT:
Another way would be, to set the relative layout to a fixed height you know (like 60dp) and set the imageView to a fixed height (like 40dp). Then the TextView will also show up below the ImageView.
Here's the layout (below). I'm trying to reposition the location of the checkbox; move it to the right of the view. android:gravity and android:layout_gravity seem to have no effect. Any explanation? This LinearLayout is a child of a Relative Layout.
<LinearLayout
android:id="#+id/deviceLinear"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="#id/view1" >
<ImageView
android:contentDescription="#string/devices_icon"
android:id="#+id/devices_img"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="0.15"
android:layout_gravity="center"
android:src="#drawable/hardware_phone" />
<TextView
android:id="#+id/devices"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="0.43"
android:text="#string/devices"
android:textSize="20sp" />
<CheckBox
android:id="#+id/check_devices"
android:button="#drawable/custom_checkbox"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="0.42"
android:onClick="onCheckboxClicked" />
</LinearLayout>
I assume that you want the CheckBox to be on the right side of the LinearLayout. Since you have given it a layout_weight it will always take up some fixed percentage of the width regardless of its size as you can see by that blue bounding box.
Try wrapping the checkbox in another LinearLayout that has android:orientation='horizontal'. Give the 0.42 weight to the wrapping LinearLayout and then set the LinearLayout's android:gravity to be right. That should keep your spacing while moving the checkbox to the far right.
Something like this:
<LinearLayout
android:orientation="horizontal"
android:layout_width="0dp"
android:layout_weight="0.42"
android:layout_height="wrap_content"
android:gravity="right" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
You might also want to consider a RelativeLayout which enables you to position Views based on where other views are.
You are giving layout_weight="0.42" to your checkbox, that means that it will be measured with a width based on the LinearLayout's width. By this approach you will never manage to put it on the right.
The best way to achieve your goal is to use a RelativeLayout. Here is my list item layout with a checkbox on the right. Sorry about the merge tag but it is merged inside a RelativeLayout with
android:layout_width="match_parent"
android:layout_height="wrap_content"
attributes
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView android:id="#+id/imgChannelIcon"

android:layout_alignParentRight="true"
android:includeFontPadding="false"
android:paddingTop="3dp"
android:paddingBottom="3dp"
android:textStyle="italic"
android:text="#string/channel_item_dummy_update"
style="?muListItemTextTiny" />
</merge>
As you can see I first place an image with layout_alignParentLeft="true" then the checkbox with layout_alignParentRight="true" and finally I arrange the other components based on those two. From your image I can see that you can use your devices_img as the left component (but you will have to give it a fixed height and maybe some margins in order to became the Layout's height) and your check box as your right.
Keep in mind that in a RelativeLayout with wrap_content as height you cannot use the AlignParentBottom attribute.
Hope this helps...
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.
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/white"
>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="#+id/summary"
android:text="Summary "
android:textSize="25px"
android:textColor="#color/black"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageView
android:id="#+id/summary_btn"
android:src="#drawable/next"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/summary"
android:layout_toRightOf="#id/summary"
android:layout_alignBaseline="#id/summary"
/>
</RelativeLayout>
<FrameLayout>
I don't want to make this image a button .
But i don't see the error.
Don't use an ImageView, use the TextView's android:drawableRight attribute.
I don't know what's special about the id "summary", but if you change your ids so that the TextView is, say, "#+id/s" and the ImageView is, say, "#+id/s_btn" (and change the references in the ImageView to "#id/s" of course) then it seems to work.
Or use alignParentEnd="true" which is more accurate and for the job. this will move the image all the way to the end of wherever its sitting in (the relativeLayout parent).
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<com.cura.classes.TypefacedEditText
android:id="#+id/passwordprompt"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ImageView
android:layout_alignParentEnd="true"
android:layout_width="30dp"
android:layout_height="30dp"
android:src="#drawable/showpassword_eye" />
</RelativeLayout>
Result:
And if you want the textField to stop at where the image begins, set its marginRight attr to the width of the image
