You need to add "android:layout_marginBottom= x dp".
Bottom/Top/Start(for left)/End(for right) for all 4 sides. And for every element.
Or if you like more design side, just pull arrows from elements to the sides and then move elements over layout.

You have constrains on your views that are only for showing in the xml layout editor but will be ignored when running on an actual device. Android studio should be giving you warnings regarding the usage of anything with the text "layout_editor_". You need to give the view real constraints.

EditText not working in text android

I'm facing an issue regarding EditText.
EditText is not working in couple of android devices when inputType:Text / TextMultiline/ TextPersonName.
but when you use inputType:Number
It works in all devices
what is the issue?
<EditText
android:id="#+id/quantity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Quantity 1Kg Meat etc"
android:focusableInTouchMode="true"
android:textIsSelectable="true"
android:clickable="true"
android:inputType="text"
android:textSize="14sp"
android:textColor="#android:color/black"
android:textColorHint="#android:color/black"
android:layout_below="#+id/line1"
android:layout_alignParentStart="true" />
Firstly it didn't show the keyboard
then i use this
android:windowSoftInputMode="stateVisible|adjustResize"
after this i can't edit the text fields
if inputType:number then it works
One thing i want to add more is i'm using this in custom ListView

I think problem with android:textIsSelectable="true" try to remove and check
<EditText
android:id="#+id/quantity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Quantity 1Kg Meat etc"
android:focusableInTouchMode="true"
android:clickable="true"
android:inputType="text"
android:textSize="14sp"
android:textColor="#android:color/black"
android:textColorHint="#android:color/black"
android:layout_below="#+id/line1"
android:layout_alignParentStart="true" />

android:inputType="textNoSuggestions|text"
android:focusable="true"
Working solution
If mobile text prediction is on then use above inputType to edit textfields

Issue in adding Hint for AutoCompleteTextView in Android with android:hint="" function [duplicate]

This question already has answers here:
How to set the hint of autocomplete textview in android
(3 answers)
Closed 5 years ago.
<AutoCompleteTextView
android:id="#+id/edtname">
I have tried android:hint and android:CompletionHint, but unable to show hint text on the AutocompleteTextView.
Thanks in advance !

Set this on xml:
<AutoCompleteTextView
android:id="#+id/autoc"
android:layout_width="wrap_content"
android:layout_height="wrap_conten"
android:ems="10"
android:text=""
android:hint="HintYouWantToGive" />

<AutoCompleteTextView
android:id="#+id/autoCompleteTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="**Your Hint**" />

Use attribute android:hint to show hint text. You should use different color for hint text and background.
<AutoCompleteTextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="This is a hint"
android:textColorHint="#000000"
android:background="#FFFFFF" >
</AutoCompleteTextView>

Positioning hint within multiline EditText - TextInputLayout

I have an EditText that has 4 lines (min=4; >4 scrolls). The EditText is embedded in a TextInputLayout. The hint displayed for this seems to be centered vertically. I'd like it at the start of the 1st line, naturally.
Important Edit: Testing without TextInputLayout allows for the hint to be positioned effectively. The problem lies with this. Any insight into how to resolve it is appreciated.
<android.support.design.widget.TextInputLayout
android:id="#+id/text_input_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusableInTouchMode="true">
<EditText
android:id="#+id/status"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:fadeScrollbars="false"
android:gravity="left"
android:hint="What's going on?"
android:inputType="textMultiLine"
android:lines="4"
android:minLines="4"
android:scrollbarStyle="outsideInset"
android:scrollbarThumbVertical="#drawable/custom_scrollbar_style"
android:scrollbars="vertical"
android:textColorHint="#color/black_semi_transparent" />
<TextView
android:id="#+id/text_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:text="140"
android:textColor="#color/black_semi_transparent" />
</android.support.design.widget.TextInputLayout>

This bug has been fixed in the v23 support libraries:

Android Spinner Gravity Not working

I'm trying for days to align the text in a spinner to right, but every time I fail to do it,
I tried to set Gravity to right, or ellipsize to end but nothing works and all I have is this :
can you please help with this issue ?
Thanks a lot.
Here's the XML :
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:orientation="horizontal" >
<org.holoeverywhere.widget.Spinner
android:id="#+id/spnCities"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:entries="#array/array_cities"
android:gravity="right"/>
<TextView
android:id="#+id/tvCities"
android:layout_width="70dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:text="#string/city"
android:textAppearance="?android:attr/textAppearanceSmall" />

You probably have to use a custom view to enable this to work. Use google its your best friend...this will probably help:
Align spinner values to right instead of left

android:textDirection="rtl"
