Android material chips

问题

I want to implement an autocomplete edittext with chips in my application and I want to do it in a way that it's done here: material design chips. First I would like to ask if there is some kind of widget (maybe as part of the new support library) or a solution that I can use for easy implementation. (I know that this question has been asked before but I just want to know if something changed in the meantime). Also I found this library, but I don't know how can I use it (and can I use it) for autocompletion of my sets of data... Has anyone worked with this library before and can share their experience?

Any help would be appreciated!

The new Material Components for Android contains the component Chip.

You can add the chip to your layout file with:

<com.google.android.material.chip.Chip
    android:id="@+id/some_chip"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="This is a chip" />

With the classic Design Support Library 28.0.0 you can use the package:

<android.support.design.chip.Chip
../>

You can customize the component using these attributes:

• android:checkable: If true, the chip can be toggled. If false, the chip acts like a button
• app:chipIcon: Used to display an icon within the chip
• app:closeIcon: Used to display a close icon within the chip

You can find the official documentation here.

I actually ended up using this library. The autocomplete view and chips that this library provides are not "materially" styled, but you can do it yourself with no great effort. After great research I realized that this library gives you the most easy way of implementing your own sets of data into the logic. All the other libraries were customized for using Android contact or emails, and it was not so trivial to change the code and query your own sets of data. So if someone wants to implement chips, but with custom data querying I'd say this is the right way to go.

Latest so far.. This library looks super and easy. You need

implementation "com.hootsuite.android:nachos:1.1.1"

and

<com.hootsuite.nachos.NachoTextView
    android:id="@+id/nacho_text_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:chipHorizontalSpacing="2dp"
    app:chipBackground="@color/chip_background"
    app:chipTextColor="@color/cheddar"
    app:chipTextSize="16dp"
    app:chipHeight="30dp"
    app:chipVerticalSpacing="3dp"/>

and

val suggestions = arrayOf("Tortilla Chips", "Melted Cheese", "Salsa", "Guacamole", "Mexico", "Jalapeno")
val adapter = ArrayAdapter(context, android.R.layout.simple_dropdown_item_1line, suggestions)
nachoTextView.setAdapter(adapter)

Play with the customization!
