How to lay horizontaly these views? - java

I want to implement the following layout:
I did it as follows:
<?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="wrap_content"
android:layout_marginTop="10dp"
android:orientation="horizontal"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical"
android:layout_marginRight="20dp"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="LABEL"
android:textSize="14sp"
android:layout_marginBottom="5dp"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:padding="10dp"
android:text="Text Box 1"
android:textSize="14sp"
/>
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
>
<LinearLayout 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="LABEL 2"
android:layout_marginBottom="5dp"
android:textSize="14sp"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:text="BLA-1"
android:background="#color/white"
android:textSize="14sp"
/>
<TextView android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:gravity="center|bottom"
android:text="and"
android:textSize="14sp"
/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:text="BLA-2"
android:background="#color/white"
android:textSize="14sp"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
</LinearLayout>
Basically I used LinearLayouts and gravity.
It works but it seems kind of complex and I noticed that when I increase the margins left and right of the and text the texts BLA-1 and BLA-2 get cut off.
Is there a better way for this?
I think I can not use a relative layout as I would not be able to have the views take these sizes across the screen, right?
UPDATE:
Also with my approach any kind of padding in the TextViews cuts off the text


This looks the same as on screenshot (just customize colors)
<?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="horizontal"
android:padding="16dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="LABEL" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFF"
android:hint="Text Box 1"
android:padding="4dp"
android:textColorHint="#757575" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="LABEL2" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFF"
android:hint="BLA-1"
android:padding="4dp"
android:textColorHint="#757575" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:text="and" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFF"
android:hint="BLA-2"
android:padding="4dp"
android:textColorHint="#757575" />
</LinearLayout>
</LinearLayout>
</LinearLayout>


I think LinearLayout is a good choise even though it is complex if you want to keep the weights.
You should change all your TextViews to wrap_content so they won't get cut off.
If you still want to avoid spaces you can wrap each TextView with a LinearLayout or FrameLayout like this:
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="LABEL2" />
</LinearLayout>


Here you can get it using Linear Layout. Have a look at below xml layout exactly what you are looking for.

Toolbar back arrow with icon

How to display icon with back arrow in android toolbar like WhatsApp ?
I would like to reduce the space between the photo and the back arrow.
How can I reduce space?
I have:
ChatActivity.java: the layout (which has only one view) is replaced with ChatFragment.java. Moreover, the toolbar is replaced here with fragment_chat_toolbar.xml
ChatFragment.java: here the inputs, the emojis, the files etc. are managed
Thanks.

My project has include page for every page. Include layout show well designed in include layout. But the owner page don't show same view

Every layouts in project has include layout. I have designed well in iclude layout. But in main layout of include layout don't show same view. for example the buttons move to the right of screen. I did different screen designs for small, normal, large and xlarge. But that didn't solve problem.

I don't know why this button move right of screen. I am doing this include layouts first time and I don't know reason of it. I can't solve it. Please help me.

Possible solution would be to use RelativeLayout to center the button with reference to it's parent instead of giving it a fixed left margin.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/btn_login"
style="?android:attr/buttonStyleSmall"
android:layout_width="185dp"
android:layout_height="wrap_content"
<!-- IMPORTANT -->
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:background="#color/colorPrimary"
android:clickable="true"
android:focusable="true"
android:text="GÖNDER"
android:textColor="#android:color/white" />
</RelativeLayout >

center content in a simple legend layout

I build a layout that overflows the google maps and it look like that: image
so the problem that i get with the layout on the bottom is that i can't center all the conter it stays too much on the left side and i don't know really why.
I want to center the content but mantain the space with each elemnt(i consider the element the background color + the text).
How can i do it?
here is my xml(that contains the map and the layout):

thanks!

You have to wrap_content your Button and you TextView, remove android:layout_weight="1" from the textView that lives beside your Button, then finally make sure that every single LinearLayout that wraps your Button and TextView are flagged as android:gravity="center" (this gravity is gonna be applied for its childs)
Also I strongly advise you replacing these linear layouts for Relatives to reduce your UI hierarchy
Try this.

You can do it simply doing by enclosing your error button inside the Relative Layout as following steps:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<Button
android:id="#+id/retry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#null"
android:drawablePadding="10dp"
android:drawableTop="#drawable/ic_android"
android:gravity="center"
android:padding="6dp"
android:text="TRY AGAIN"
android:textColor="#000"
android:textSize="35sp"
android:visibility="visible" />
</RelativeLayout>

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"/>
also you need a RelativeLayout for parent of this tag

Make the parent layout as RelativeLayout and put everything inside RelativeLayout except the button.
use
<RelativeLayout 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="match_parent">
<!--Put your other codes here-->
<!--everything can be within LinerarLayout-->
<Button
android:id="#+id/retry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#null"
android:drawablePadding="10dp"
android:drawableTop="#mipmap/retry"
android:onClick="onClickRetry"
android:padding="6dp"
android:text="TRY AGAIN"
android:textColor="#000"
android:textSize="35sp"
android:visibility="gone" />
</RelativeLayout>
as your button code

Android layout inconsistency

I have a layout that is being displayed in two different layouts. First one is being displayed in a LinearLayout and it behaves as expected:
However, when this layout is part of a listview, the textview is not centered:
Here's the 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="130dp"
android:orientation="vertical">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:orientation="horizontal"
android:padding="5dp">
<com.parse.ParseImageView
android:id="#+id/iv"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:scaleType="fitCenter"/>
<TextView
android:id="#+id/tv_title"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2.5"
android:layout_marginLeft="10dp"
android:textAppearance="#android:style/TextAppearance.Holo.Medium"
android:ellipsize="end"
android:maxLines="3"
android:textStyle="bold"
/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="25dp"
android:orientation="horizontal"
android:paddingLeft="10dp">
<View
android:layout_width="20dp"
android:layout_height="20dp"
android:background="#color/blue"
android:layout_gravity="center"
/>
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#color/gray"
android:layout_margin="7dp"
/>
<TextView
android:id="#+id/tv_source"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:textAppearance="#android:style/TextAppearance.Holo.Small"
android:gravity="center"/>
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#color/gray"
android:layout_margin="7dp"
/>
<TextView
android:id="#+id/tv_date"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:fontFamily="sans-serif-light"
android:textAppearance="#android:style/TextAppearance.Small"
android:gravity="center"/>
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#color/gray"
android:layout_margin="7dp"
/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_fire"
android:layout_gravity="center"/>
<TextView
android:id="#+id/tv_viewCount"
android:layout_marginLeft="5dp"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:fontFamily="sans-serif-light"
android:textAppearance="#android:style/TextAppearance.Small"
android:gravity="center"/>
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="5dp"/>
</LinearLayout>
<ImageView
android:id="#+id/pin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_pin"/>
<TextView
android:id="#+id/comment_tv"
android:layout_width="0dp"
android:layout_height="0dp"
android:textColor="#color/white"
android:layout_alignTop="#+id/pin"
android:layout_alignBottom="#+id/pin"
android:layout_alignLeft="#id/pin"
android:layout_alignRight="#+id/pin"
android:gravity="center"
android:layout_marginBottom="10dp"/>
</RelativeLayout>
The textView that I am referring to is at the bottom with id comment_tv
What am I doing wrong?
Thanks

Your pin+text inside a relative layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="60dp"
android:layout_gravity="center_vertical" >
<ImageView
android:id="#+id/pin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_pin"/>
<TextView
android:id="#+id/comment_tv"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignTop="#id/pin"
android:gravity="center"
android:layout_marginTop="10dp" //set this higher if you need
android:layout_centerHorizontal="true" //if this text will be not in the center
//you can use the "layout_marginLeft" to put whatever you want
/>
</RelativeLayout>
This should but the text on the spot you want

I tried it with your image and this is my result with underlying code. Is this what you are looking for?
<?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:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/sample"
android:gravity="center"
android:text="12"
android:textSize="18sp" />
</LinearLayout>
And heres a snapshot of this code:
