Android Chips: Dynamicaly add remove tags ( Chips View)

Chips are material design components. Chips can be used to enter information, make selections, filter content, or trigger actions

There are four types of chips 1. Entry Chips, 2.Filter Chips 3.Choice Chips 4. Action Chips

We will make a tag add and remove like functionality using entry chip.

We have defined a ChipGroup in XML file to add Chip view dynamically.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:id="@+id/filter_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
   >
    <android.support.design.chip.ChipGroup
        android:id="@+id/tag_group"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
   />
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

android:id="@+id/filter_container"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="vertical"

<android.support.design.chip.ChipGroup

android:id="@+id/tag_group"

android:layout_width="match_parent"

android:layout_height="wrap_content"

</LinearLayout>

Add Chip View to ChipGroup

Entry chip has a remove icon along with a chip Thumbnail. We have set setOnCloseIconClickListener on entry Chip instance to remove tags.

import android.os.Bundle;
import android.support.design.chip.Chip;
import android.support.design.chip.ChipGroup;
import android.support.v7.app.AppCompatActivity;
import android.util.TypedValue;
import android.view.View;

import java.util.ArrayList;
import java.util.List;


public class TagActivity extends AppCompatActivity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tag);
        setTag(tagList); //Pass tag list to show tag view.
    }
    
    private void setTag(final List<String> tagList) {
        final ChipGroup chipGroup = findViewById(R.id.tag_group);
        for (int index = 0; index < tagList.size(); index++) {
            final String tagName = tagList.get(index);
            final Chip chip = new Chip(this);
            int paddingDp = (int) TypedValue.applyDimension(
                    TypedValue.COMPLEX_UNIT_DIP, 10,
                    getResources().getDisplayMetrics()
            );
            chip.setPadding(paddingDp, paddingDp, paddingDp, paddingDp);
            chip.setText(tagName);
            chip.setCloseIconResource(R.drawable.ic_action_navigation_close);
            chip.setCloseIconEnabled(true);
           //Added click listener on close icon to remove tag from ChipGroup
            chip.setOnCloseIconClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    tagList.remove(tagName);
                    chipGroup.removeView(chip);
                }
            });

            chipGroup.addView(chip);
        }
    }
}

private void setTag(final List<String> tagList) {

final ChipGroup chipGroup = findViewById(R.id.tag_group);

for (int index = 0; index < tagList.size(); index++) {

final String tagName = tagList.get(index);

final Chip chip = new Chip(this);

int paddingDp = (int) TypedValue.applyDimension(

TypedValue.COMPLEX_UNIT_DIP, 10,

);

chip.setPadding(paddingDp, paddingDp, paddingDp, paddingDp);

chip.setText(tagName);

chip.setCloseIconResource(R.drawable.ic_action_navigation_close);

chip.setCloseIconEnabled(true);

//Added click listener on close icon to remove tag from ChipGroup

chip.setOnCloseIconClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

tagList.remove(tagName);

chipGroup.removeView(chip);

}

});

chipGroup.addView(chip);

}

I do my code from this example
But now I have only one query
From recyclerview click I add chip
And from chip clone icon I remove chip…..
But now question is how I remove particular chip from click of recycler view item.
