Android Material Chips

A different approach to implement android material chips since using transformed images inside an EditText cause too many exceptions on older devices and older versions.

Features

Enter an email address and it will automatically transform into a chip

Email validation dialog

*** UPDATE: The dialog is not included in version 1.2.0 anymore. Show your own dialog instead. ***

Customize your layout and text

Sample

APK: sample-apk-1.0.1

Download

Gradle:

via jCenter

buildscript {
    repositories {
        jcenter()
    }
}

dependencies {
    compile 'com.doodle.android:android-material-chips:1.2.0'
}

via JitPack.io

repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    compile 'com.github.DoodleScheduling:android-material-chips:1.2.0'
}

Usage

Use the ChipsView class in your layout file.

<com.doodle.android.chips.ChipsView
    android:id="@+id/chipsView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

Customize

Layout

Include xmlns:app="http://schemas.android.com/apk/res-auto" and customize your layout file.

<com.doodle.android.chips.ChipsView
	android:id="@+id/chipsView"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	app:cv_max_height="120dp"
	app:cv_vertical_spacing="2dp"
	app:cv_bg_color="#f00"
	app:cv_bg_color_clicked="#0f0"
	app:cv_color="#00f"
	app:cv_color_clicked="#721"
	app:cv_text_color="#199"
	app:cv_text_color_clicked="#180"
	app:cv_bg_color_indelible="#f00"
	app:cv_text_color_indelible="#0f0"
	app:cv_icon_placeholder="@drawable/ic_bug_report_24dp"
	app:cv_icon_placeholder_tint="#06f"
	app:cv_icon_delete="@drawable/ic_close_24dp"
	app:cv_text_hint="This is the hint text"
	app:cv_chips_margin="2dp"

====== Find the View in your Activity or Fragment class.

mChipsView = (ChipsView) findViewById(R.id.chipsView);

Listener

The ChipsView provides a listener to interact with your data.

mChipsView.setChipsListener(new ChipsView.ChipsListener() {
    @Override
    public void onChipAdded(ChipsView.Chip chip) {
        // chip added
    }

    @Override
    public void onChipDeleted(ChipsView.Chip chip) {
        // chip deleted
    }

    @Override
    public void onTextChanged(CharSequence text) {
        // text was changed
    }
            
    @Override
    public boolean onInputNotRecognized(String text) {
        // return true to delete the input
        return false; // keep the typed text
    }
});

Add a new chip

mChipsView.addChip(email, imgUrl, contact);

Add a non-removable chip.

mChipsView.addChip(email, imgUrl, contact, true);

Remove a chip

mChipsView.removeChipBy(contact);

Add Custom chip validator

mChipsView.setChipsValidator(new ChipsView.ChipValidator() {
    @Override
    public boolean isValid(Contact contact) {
        return true;
    }
});
