This layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="90sp"
android:text="5000"
android:id="#+id/textView"
android:layout_gravity="center"
/>
</LinearLayout>
produces the following:
I want to get rid of the top and bottom margin. Where are they coming from in the first place? Maybe for certain letters in certain fonts/languages.
There is already a thread for this question, but none of the answers really work in all situations or the solutions are hacks. There has to be a simple way.
First idea from the thread: android:includeFontPadding="true" (does not change anyting)
Second idea from the thread: android:height="90sp" (removes at least bottom margin)
So, I changed my layout regarding the ideas:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="90sp"
android:text="5000"
android:id="#+id/textView"
android:layout_gravity="center"
android:includeFontPadding="true" <!-- idea 1 -->
android:height="90sp" <!-- idea 2 -->
/>
</LinearLayout>
Still it procudes a top margin:
Third idea from the thread: android:layout_marginTop="-12sp"
If add this property it looks at least as desired. But -12sp seems so arbitrary to me. I just adjusted this value via trial and error and I don't like that.
This does not seem like a clean solution to me. This is such a simple thing, I just cannot believe how Android can make it so hard, that you have to use hacks.
Is there a clean solution out there?
Use the below syntax to set text size programmatically and set the required size in dimes file.
textView.setTextSize(getResources().getDimension(R.dimen.textsize));
To set padding use below code based on your needs
yourTextView.setPadding(0, 10, 0, 0);
Set Linearlayout and TextView padding and margins to 0dp. Should work.
Add those to both views:
android:padding="0dp"
android:layout_margin="0dp"

So I'm learning app development for Android, and I'm a bit stuck. I'm trying to make a RecyclerView with CardViews, but there is just too much space between CardViews. This is what it looks like.
I'm going for more of the look that the Google app has with the feed.
This is more like what I'm shooting for.
Anyways, I've searched and searched on this website for a solution to my problem and nothing seems to be working for me. I'm hoping that someone can give me something that will actually work.
Here's the xml for my cardview:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="10dp">
<android.support.v7.widget.CardView
android:id="#+id/cv"
android:layout_width="match_parent"
android:layout_height="120dp"
app:cardCornerRadius="10dp"
app:cardElevation="5dp"
app:cardUseCompatPadding="true"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp">
<TextView
android:id="#+id/note_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="false"
android:layout_below="#+id/event_time"
android:textSize="24sp" />
<TextView
android:id="#+id/note_content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/note_title" />
</RelativeLayout>
</android.support.v7.widget.CardView>
The top and bottom spaces is caused by your padding
android:paddingBottom="10dp", remove this or reduce it
Decrease the PadingBotom of the root constraintLayout
you could put 3 or 4 dp instead of 10dp.
android:paddingBottom="10dp"
Also I do not know if the copy of your code was not good ... the constraintLayout must close at the end:
after this:
</android.support.v7.widget.CardView>
you must have this:
</android.support.constraint.ConstraintLayout>
From the documentation for CardView:
Before Lollipop, CardView adds padding to its content and draws shadows to that area. ... If you want CardView to add inner padding on platforms Lollipop and after as well, you can call setUseCompatPadding(boolean) and pass true.
In your layout, you have this attribute on your CardView tag:
app:cardUseCompatPadding="true"
This does the same thing as the method in the quote above.
As a result, even if you had zero margin on all sides of your cards, users would still see space in between them because of the inner padding behavior. If you want really tight spacing, you'll have to remove this attribute (though of course you'll still get the larger spacing pre-Lollipop).
For the last two hour and a half i had been trying to do something really simple: change the padding in the Android's AutoCompleteTextView's popup (the one that shows the auto complete options).
i'm trying to do this because the item in my app has the height of the text (i'm not sure why), so i want to make it easier to click on. But every think i could find didn't work at all.
So i really would be glad if anyone could spot a light in this problem or give an alternative solution.
And just for the record, i'm using android studio, and i had removed the support API (since my min API is 16), so my app is using 100% native resorts only.
I just found a way to make it, i had to make a custom view layout with an textview already including the item's padding. Than i created a custom adapter with uses this layout.
The layout goes like this
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:singleLine="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:layout_margin="0dp"
android:paddingLeft="#dimen/thin_margin"
android:paddingRight="#dimen/thin_margin"
android:paddingTop="#dimen/list_1line_item_padding"
android:paddingBottom="#dimen/list_1line_item_padding"/>
And in the custom adapter just used it in the getView method
itemView = LayoutInflater.from(ctx).inflate(R.layout.list_1line_item, null);
<?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"
android:layout_marginTop="20dp"
>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="#dimen/dp_15"
android:paddingBottom="#dimen/dp_15"
android:id="#+id/parentid">
<AutoCompleteTextView
android:id="#+id/address_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/light_gray_bg"
android:drawableRight="#drawable/icon_search_smaller"
android:gravity="center_vertical"
android:hint="Start typing location"
android:inputType="textCapWords"
android:popupBackground="#drawable/auto_location_popup_bg"
android:textColor="#color/black"
android:textColorHint="#color/dark_grey"
android:textSize="16sp"
android:visibility="visible"
android:dropDownWidth="wrap_content"
android:dropDownAnchor="#+id/parentid">/>
<requestFocus />
</RelativeLayout>
</RelativeLayout>
define another relative layout wrapping only the autocomplete textview and the button. look at this link
Android layout padding is ignored by dropdown
The following XML results in the below image.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/convoLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/right_bubble">
<TextView
android:id="#+id/convoBody"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true" // cause
android:padding="5dp"
android:text="test test test test"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
Is anyone aware of how to get it to look like this:
Note: I need the RelativeLayout as this is a dumbed down version of my XML :).
EDIT:
Let me also clarify. Without android:layout_alignParentRight="true" in the TextView, the layout looks like the image below (there is white padding on the right)
In essence, I need that padding on the left.
EDIT2:
To further clarify, #drawable/right_bubble is a 9-patch image that is meant to stretch to house the inner views dynamically and the RelativeLayout is to have 3 TextViews inside of it, in which the 9-patch image should encapsulate all 3.
EDIT3:
This is what I want the end result to look like
you are setting the background to relative layout... so, whole layout will have same background no matter what views it holds. Try setting "android:background="#drawable/right_bubble" to TextView instead.
EDIT (by OP after getting answer from comments):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/convoLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right" // added
android:background="#drawable/right_bubble" >
<TextView
android:id="#+id/convoBody"
android:layout_width="wrap_content"
android:layout_height="wrap_content" // removed layout_alignParentRight
android:padding="5dp"
android:text="test test test test"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
J.Ajendra's answer got me most of the way there. His answer (that I edited in after understanding his comments) worked, but only if the RelativeLayout's container honors android:layout_gravity. (for example, if we were to Activity#setContentView(R.layout.convo_item)).
In my case, convo_item.xml was to be inflated into a ListView which overrides this behavior for RelativeLayouts (I'm not sure why, but it does) resulting in the chat bubble always being on the left. To solve this, I simply wrapped the RelativeLayout in a LinearLayout that took the parents entire width (android:layout_width="match_parent") and set the gravity of it's content to "right" (android:gravity="right"). The result, it works for all cases including ListViews and Activity#setContentView(...).
Here's the code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/convoOuterLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right" >
<RelativeLayout
android:id="#+id/convoLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/right_bubble" >
<TextView
android:id="#+id/convoBody"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:text="test test test test"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
</LinearLayout>
I made a compound control, but when i add this new component into a XML layer with other standard components(e.g. TextView), when this layer is inflated, the compound control has a big margin added in the bottom separating this from the others components. I tried adding Layer_bottomMargin = 0dp without success, the only way to resolve this, is adding layer_height a fixed value (i.e. 15dp) instead "wrap_content", but this solution is not fine for me, due i want remove dinamically some component from my compound control.
The code of my compound control:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="left|top"
android:clickable="false"
android:background="#CCCCCC"
android:layout_marginTop="#dimen/fieldset_margin"
>
<TextView
android:id="#+id/header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/title_default"
android:textSize="14sp"
/>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="#color/fieldset_lines_shadow"
/>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="#color/fieldset_lines_light"
/>
</LinearLayout>
And the code of my layer including this compound control:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#C8D5F6FF"
android:gravity="top"
android:layout_margin="8dp"
>
<com.apps.example.Header
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#color/fieldset_text_secondary"
android:text="nananananan"
android:textSize="10sp"
android:layout_marginLeft="#dimen/fieldset_margin"
/>
</LinearLayout>
Sorry but this is my first post and i can't upload images.
Thanks in advance.
I resolved partially by overwriting the onMeasure method in my compound control class. I did not this before because in the official documentation:
http://developer.android.com/guide/topics/ui/custom-components.html
says that is not necessary overwrite this method when is creating a compound control.
Anyway, this is partial solution due when an individual control of the compound is programmatically turned invisible (GONE) occurs the same issue mentioned in the original post but with smaller margin space.
I will continue trying to resolve this, but for now, this is my solution.
Thanks!
I would like to design a frame using 4 ImageView for each of the top, bottom, left and right side of that frame, as shown in the following example:
Seems simple, but I am really having a hard time doing it. I tried using a FrameLayout along with layout_alignParentLeft|Right|Top|Bottomlike the following:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/camera_masque"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFFFFF"
>
<ImageView
android:id="#+id/camera_top_masque"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_top_masque_photo"
android:layout_alignParentTop="true"
/>
<ImageView
android:id="#+id/camera_left_masque"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/ic_left_masque_photo"
android:layout_alignParentLeft="true"
/>
<ImageView
android:id="#+id/camera_right_masque"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/ic_right_masque_photo"
android:layout_alignParentRight="true"
/>
<ImageView
android:id="#+id/camera_bottom_masque"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_bottom_masque_photo"
android:layout_alignParentBottom="true"
/>
</FrameLayout>
It works well for the top and left sides, but not for the others (like it places the right and bottom sides on the top side...).
I also tried using a RelativeLayout like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/camera_masque"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFFFFF"
>
<ImageView
android:id="#+id/camera_top_masque"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_top_masque_photo"
android:layout_alignParentTop="true"
/>
<ImageView
android:id="#+id/camera_left_masque"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="-2dp"
android:src="#drawable/ic_left_masque_photo"
android:layout_below="#id/camera_top_masque"
/>
<ImageView
android:id="#+id/camera_right_masque"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:src="#drawable/ic_right_masque_photo"
android:layout_marginRight="-2dp"
android:layout_below="#id/camera_top_masque"
android:layout_alignParentRight="true"
/>
<ImageView
android:id="#+id/camera_bottom_masque"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_bottom_masque_photo"
android:layout_alignParentBottom="true"
/>
</RelativeLayout>
But same thing, does not work as expected.
Any idea what is wrong with my layouts? How could I accomplish this?
Note: Images sizes are: 640*114px (top, bottom) and 34*572 (left, right).
Thanks!
I usually use linearlayout for things like this and control the fill using layout_weight parameters. You will probably find a lot of similar questions here.
Simply create a vertical linear layout and in the middle section create a horizontal linear layout.
This is made a lot simpler if you use the WYSIWYG layout designer in Eclipse ADT ... .see tools.android.com for details
There are a lot of tutorials available for Android layouts which are a more useful resource as Stack Overflow tends to deal with the programming issues rather than layouts.
I will answer my own question in order to highlight the mistakes I have made. Turns out, I was almost there, I only had to add an alignParentTop at both the right and left ImageViews and an alignParentLeftat the bottom ImageView.
I don't understand the logic behind this, though! (if someone could explain...)
If the frame are built by the same images. You can try a 9-patch drawable or a shape with borders and transparent center.
