In my observation, the EditText pictured below is separated into 2 parts: one being a simple grid of which values are saved, and another being an actual EditText.
Has any of you know any EditText library that performs similarly like this? Or is there any alternative solution? Thanks!
That is called Chips - Components - Google design guidelines
See this libraries below :-
TokenAutoComplete
Material Chips
For example Add in your layout like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.tokenautocomplete.ContactsCompletionView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
And all is done
Or You can create by your own using SpannableStingBuilder and ImageSpan

I have seen this post before with the same question, but recently Google introduced another TabLayout
QUESTION:
Is there a way of reducing the space between text and icon using an attribute for instance, or another google-maintainable method in order to avoid having to go through creating a separate layout with text and an icon?
My current layout looks like this:
<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">
<androidx.viewpager.widget.ViewPager
android:id="#+id/mViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/homeTabs">
<com.google.android.material.tabs.TabLayout
style="#style/Widget.MaterialComponents.TabLayout"
android:id="#+id/homeTabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:tabIndicatorColor="#color/clear_blue">
<com.google.android.material.tabs.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:icon="#drawable/one_svg"
android:text="#string/one"/>
<com.google.android.material.tabs.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:icon="#drawable/two_svg"
android:text="#string/two"/>
<com.google.android.material.tabs.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:icon="#drawable/three_svg"
android:text="#string/three"/>
<com.google.android.material.tabs.TabItem
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:icon="#drawable/four_svg"
android:text="#string/four"/>
</com.google.android.material.tabs.TabLayout>
</RelativeLayout>
As I could understand after some tests, no.
The Google Tab Item is created to match with the material design rules, so the space between icon and text is calculated following that rules, as you can read here in the post you reported.
Only way is to create a custom layout, with an ImageView and a TextView and inflating it in the TabItem.
I suggest you this way, because is fully customizable so you can create pratically what you want.
Hope I helped you! If you have any question write a comment.
No, looks like you cannot do that with just attribute. This change will definitely require creating custom layout. And this gonna be the right way - almost any application has custom views. But this class looks complicated (there is source code). So there is inner class TabView, that contains ImageView and TextView, and there is method inflateAndAddDefaultIconView(). The easiest way for you my opinion is just to copy that class into your project and change it as you need, the license (Apache 2.0) allows you to do that.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"
tools:context="com.bignerdranch.android.geoquiz.CheatActivity">
<TextView
android:id="#+id/answer_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="24dp"
tools:text="Answer"/>
I am a novice in programming. I started with Big Nerd Ranch programming book. I came across this code. In the book it is stated as:
"This namespace allows you to override any attribute on a widget for the
purpose of displaying it differently in the Android Studio preview. Since TextView has a text attribute,
you can provide a literal dummy value for it to help you know what it will look like at runtime. The
value “Answer” will never show up in the real app. Handy!"
What does that actually mean? I am completely new. I know this is foolish question, please help me in this.
Thanks to that line
xmlns:tools="http://schemas.android.com/tools"
you can use in all your XML something like that
tools:text="Answer"
Thanks to that line
xmlns:android="http://schemas.android.com/apk/res/android"
you can use in all your XML element the android attribute, for example
android:id="#+id/answer_text_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="24dp"
The book you're reading is a good book, keep continue and don't give up!
Tools is basically a collection of extra properties you can add to your TextView that assist you when designing layouts in Android Studio. In this particular example, tools:text allows you to put a fake value into your TextView which will only show up in the the layout preview in Android Studio.
This will allow you to see what a TextView looks like when designing your layout in Android Studio, but you don't have to worry about removing that dummy text from your layout when you build a "real" version of your app for a phone.

I use latest Android Studio and SDK. In preview & real device i see this:
My code:
<?xml version="1.0" encoding="utf-8"?>
<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="match_parent"
tools:context="com.myappname.view.AboutActivity">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/listViewAbout" />
</RelativeLayout>
How i make subtitle text color is gray? Like this:
I'm going out on a limb and assume that you're using the row layout simple_list_item_2.xml (based on the screenshot) which gives you two rows. The problem, if you may call it that, is that depending on the SDK version, the styling for this layout has changed.
On SDK 23, it looks like this:
However, on say SDK 19, it looks like this:
Why?
To understand this we first need to take a look at the xml that generates the rows from simple_list_item_2.xml, you'll see it's a pretty simple layout that uses the now deprecated view TwoLineListItem but that's just a plus on why to use your custom layout.
<TwoLineListItem xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/listPreferredItemHeight"
android:mode="twoLine"
android:paddingStart="?attr/listPreferredItemPaddingStart"
android:paddingEnd="?attr/listPreferredItemPaddingEnd">
<TextView android:id="#id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:textAppearance="?attr/textAppearanceListItem" />
<TextView android:id="#id/text2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/text1"
android:layout_alignStart="#id/text1"
android:textAppearance="?attr/textAppearanceListItemSecondary" />
</TwoLineListItem>
The reason is because of the way the style textAppearanceListItemSecondary is resolved in each SDK version. The style is what gives the text the size, the color, etc. The evolution of the interface in Android has given birth to a huge ecosystem of themes and relying on the default styling will result in inconsistencies like the one you stumbled upon.
What to do about it?
You should use your own layout for this to allow for uniform styling across versions. To do so, please refer to any of the multiple questions covering this matter. But in short it just means creating a layout file, call it for example custom_row.xml and having the layout look exactly as you please. This also gives you total control over placement of the items, extra Views that you may need, and overhead in terms of coding is minimal compared to the SimpleAdapter or ArrayAdapter that perhaps you were using.
Note
You should consider moving your code towards RecyclerView instead of ListView if you haven't already.
You can set Textview property
android:textColor="#color/grey"
in you Adapter layout to change colour of your sub item
Hope this will help
The texts can be entered into them . Only these two text widgets are possible in the given activity. I would want to know the structure , I would have to employ to get result as such.
I am still in learning phase.
There's a lot of ways how to achieve that. I suggest you to start with reading this thoroughly to learn how to build layouts on Android.
In general, you can add spacing among views by adding some margin and/or padding.
If you want to replicate the particular design quickly, do this:
Have vertical LinearLayout as your root layout (with gray background).
Add two CardViews (one for each box). That will add the
background and spacing.
Add other views to those CardViews.
To give you something to work on
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"> //Elements inside this will be added vertically on the screen
<EditText
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_margin="10dp"
android:hint="First edittext"/>
<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp"
android:hint="Second edittext"/>
</LinearLayout>
This is the basic structure on the image you showed. Expirement with it. Add your desired borders by using shapes and etc.
I am developing my first Android app. Although I have 15 years of Java software development experience, Android is new to me. My desired look is a background image with other images on top of it, as well as labels and phone numbers. It seems like the best way to accomplish this is a Linear Layout for the background image, with a nested layout for the other fields on top of that. I have searched online and cannot find any sample code on how to accomplish this. Any recommendations would be greatly appreciated. Thanks in advance.
What are you using to develop? If you are you using Eclipse with the Android SDK this is super easy. Put the desired picture in the appropriate drawable folder, go to the graphical view of layout that corresponds to your activity, on the right side of the screen there is a list of all the properties, find background, then select your picture from drawables. You can also do this from the xml using android:background="#drawable/yourPic". This way you don't have to worry about having things layered on top of it.
I think you should go through followings:
1. http://phandroid.com/2011/05/11/10-tips-for-android-ui-design/
2. http://mobile.tutsplus.com/series/android-user-interface-design/

If I got, something like this can work:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<stuff>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<stuff>
</RelativeLayout>
<stuff>
</RelativeLayout>
I used it in an app, and made the trick.
First of all, RelativeLayout is the best layout to use. It depends on your design.
If your design says to keep all the views either vertically OR horizontally, you can use LinearLayouts in between.
My suggested way:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout android:id="#+id/layout1"
android:layout_width="match_parent"
android:layout_height="wrap_parent"
android:orientation="Horizontal">
<View1 />
<View2 />
</LinearLayout>
</LinearLayout android:id="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="wrap_parent"
android:orientation="Vertical"
android:layout_below="#id/layout1">
<View3 />
<View4 />
</LinearLayout>
</RelativeLayout>
Which will yield you something like this
