I'm using mpandroidchart to generate a chart on one-third of my device screen. As I move towards the edge of the screen the TextView gets cutoff by the padding on the sides on the parent container. Is there a way to fix it without changing my UI?
Towards the edge: (gets cutoff)
Away from the edge: (appears good)
marker_view.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:background="#drawable/my_marker">
<TextView
android:id="#+id/textViewMarker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="7dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"

android:textSize="12dp"
android:textColor="#android:color/white"
android:ellipsize="end"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
You can apply the
android:clipChildren="false"
android:clipToPadding="false"
on your TextView's parent.
Did you tried gravity attribute?
Try this method to make the text align center.
android:gravity="center"
make sure that, use android:gravity , dont use android:layout_gravity.

I'm trying to create a simple component in my layout, where there are two TextViews horizontally next to each other. The one on the right should start where the one on the left finishes. My code for this is as follows:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"
android:textColor="#android:color/white"
android:textIsSelectable="false"
android:textSize="25sp" />
<TextView
android:id="#+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:textColor="#android:color/white"
android:textSize="20sp" />
</LinearLayout>
I programmatically set the text on each TextView after the view has rendered. However, sometimes the text does not display correctly in the first TextView- I can see that the width has been set correctly, as the second TextView is not next to it, but the text is truncated rather than using the space. If I lock/unlock the device to refresh the screen then the text displays correctly (without the widths of the TextViews changing).
I've tried changing this to use a RelativeLayout, but I see the same issue.
Any ideas?
Although i dont understant what exactly you mean, would suggest you to use weightSum property in the parent view and android:layout_weight in child views. The same allows to put many child views inside a parent view with respect to ratio (like navigation tabs).
for eg :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1" >
<TextView
android:id="#+id/text1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"
android:textColor="#android:color/white"
android:textIsSelectable="false"
android:textSize="25sp"
android:layout_weight="0.4" /> //60% width
<TextView
android:id="#+id/text2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:textColor="#android:color/white"
android:textSize="20sp"
android:layout_weight="0.6" /> //40% width
</LinearLayout>
also, dont forget to put the width if child views as 0dp. as that will result in ignoring the calculations regarding the width of view. or you can set the width of child view as "match_parent" as well. any other property to width will not work. (and if you want half matchparent for both child views set layout_width to 0.5 both views.. ithink thats obvious to note)
Hopw it helps.
I have this XML layout in my App (example of one button):
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scrollViewMain"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff0e8" >
///some views
<Button
android:id="#+id/btnVysledkySportka"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/chckSprotka"
android:layout_alignRight="#+id/chckSprotka"
android:layout_alignTop="#+id/chckSprotka"
android:layout_margin="3dp"
android:layout_toRightOf="#+id/textView3"
android:background="#ffe118"
android:gravity="center"
android:onClick="vysledkySportka"
android:text="Archiv výsledků"
android:textStyle="bold" />
///some views
</RelativeLayout>
</ScrollView>
But when I start my app at Android 4.3, the text of buttons isn´t in center of button. Look at the screenshot (in red rectangle):
Where can be problem?
EDIT:
Whole layout
When you specify:
android:layout_alignBottom="#+id/chckSprotka"
android:layout_alignRight="#+id/chckSprotka"
android:layout_alignTop="#+id/chckSprotka"
It does make the bottom/right/top edge of your button match the bottom edge of the given anchor view ID & accommodates bottom/right/top margin, but while doing that, the android_gravity does not take the resultant height/width into consideration.
So the gravity of the text is center according to wrap_content for layout_height and layout_width.
You can verify that by setting values for layout_height and layout_width (Eg. 200dp and 100dp to try with) and you will get the text with gravity center but for that height and width.
To confirm the same, what you can do is use a container LinearLayout for your Button like:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/chckStastnych"
android:layout_alignRight="#+id/chckStastnych"
android:layout_alignTop="#+id/chckStastnych"
android:layout_margin="3dp"
android:layout_toRightOf="#+id/textView3"
android:background="#ffe118" >
<Button
android:id="#+id/btnVysledkyStastnych"
android:layout_gravity="center"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffe118"
android:gravity="center"
android:onClick="vysledkyStastnych"
android:text="Archiv výsledků"
android:textStyle="bold" />
</LinearLayout>
Set the gravity of LinearLayout as center and then center the Button within or as shown above, use layout_gravity for the button to center it in parent LinearLayout.
This will work as a solution when you do that for all 4 buttons, however there might be better options if you restructure your xml and avoid this kind of nesting.
Try This:
<Button
android:id="#+id/btnVysledkySportka"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/chckSprotka"
android:layout_alignRight="#+id/chckSprotka"
android:layout_alignTop="#+id/chckSprotka"
android:layout_margin="3dp"
android:layout_toRightOf="#+id/textView3"
android:background="#ffe118"
android:gravity="center_vertical"
android:onClick="vysledkySportka"
android:text="Archiv výsledků"
android:textStyle="bold" />
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 have an EditText in my application. I want to align the text in it to the right instead of the default left. I tried adding
android:layout_gravity="right"
but this doesn't seem to work. any other suggestions please?
You should use android:gravity="right". layout_gravity is for the view (EditText) alignment against the container.
You may use android:layout_alignParentRight="true" to align the EditText's right edge to its parent's right edge. Also, if you really want to use the layout_gravity or gravity attributes, check out this article that discusses the proper use of them.
You can jst set property for edit text in property window i.e. Gravity to right or by adding code of lin e in xml file of UI : android:gravity="right"
layout_gravity means that you are specifying the layouts attribute, not the element inside. In some conditions, such as layout_width and layout_height is wrap_content, layout specifications can give what you want about the element inisde your layout, since the boundries of the layout and the element (not elements) are the same..
use layout width and height as wrap content inside relative layout :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/icon"
android:layout_width="64dp"
android:layout_height="64dp"
android:layout_alignParentStart="true"
android:paddingEnd="16dp"
android:paddingStart="8dp"
tools:src="#mipmap/ic_launcher"
android:layout_alignParentLeft="true"
android:paddingRight="16dp"
android:paddingLeft="8dp"
android:contentDescription="#string/todo" />
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toEndOf="#id/icon"
android:maxLines="1"
android:lines="1"
android:paddingTop="8dp"
tools:text="Google"
android:layout_toRightOf="#id/icon" />
<TextView
android:id="#+id/last_used"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:paddingTop="8dp"
tools:text="Last used: yesterday at 18.54" />
</RelativeLayout>
I am trying to layout 1 textview (upText) left aligned and 1 textview (downText) and an image view (image) both on the same line and right aligned.
how can I do that? I tried that, but both 'textview' and image view at left aligned.
<TextView
android:id="#+id/uptext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="left"/>
<TextView
android:id="#+id/downtext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:gravity="right|bottom"/>
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right|bottom"/>
</LinearLayout>
Don't use a LinearLayout. Use a RelativeLayout, with
your first TextView set with android:layout_alignParentLeft="true"
your second TextView set with android:layout_alignParentBottom="true" and android:layout_alignParentRight="true"
something similar for your ImageView, which presently looks like it is going to overlap the second TextView
I realize this post is a bit old but just in case someone comes across this in their search for clarity;
The parent linear layout is where gravity needs to be specified for the child to align with the desired behavior which is why the above posts are explaining that linear layout is not possible for two separate behaviors to occur since a child cannot decide where to align itself within a linear layout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="200dp"
android:layout_height="50dp"
android:gravity="bottom|right">
<TextView
android:layout_width="40dp"
android:layout_height="20dp"
android:text="test"/></LinearLayout>
It should also be said that the parent linear layout must have a defined size and not be wrap-content or this will not work since wrap content implies that there will be no extra space in the layout for positioning, so at least 'match-parent' for width and height is necessary as well as having a parent with a greater size than wrap-content for the child linear layout itself.
Hope this helps.
Using RelativeLayout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="bottom">
<TextView
android:id="#+id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="hi"
android:textStyle="bold|italic"
android:gravity="right"/>
<TextView
android:id="#+id/text2"
android:layout_below="#id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="All"
android:gravity="right"/>
</RelativeLayout>
