This example demonstrate about How to delete element from linked list for listview in Android
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayoutxmlns: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 = ".MainActivity"
   android:orientation = "vertical">
   <EditText
      android:id = "@+id/name"
      android:layout_width = "match_parent"
      android:hint = "Enter Name"
      android:layout_height = "wrap_content" />
   <LinearLayout
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content">
      <Button
         android:id = "@+id/save"
         android:text = "Save"
         android:layout_width = "wrap_content"
         android:layout_height = "wrap_content" />
      <Button
         android:id = "@+id/refresh"
         android:text = "Refresh"
         android:layout_width = "wrap_content"
         android:layout_height = "wrap_content" />
      <Button
         android:id = "@+id/delete"
         android:text = "Delete"
         android:layout_width = "wrap_content"
         android:layout_height = "wrap_content" />
   </LinearLayout>
   <ListView
      android:id = "@+id/listView"
      android:layout_width = "match_parent"
      android:layout_height = "wrap_content">
   </ListView>
</LinearLayout>
In the above code, we have taken name as Edit text, when user click on save button it will store the data into arraylist. Click on delete button to delete the record from listview.
Step 3 − Add the following code to src/MainActivity.java
package com.example.andy.myapplication;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
import java.util.LinkedList;
public class MainActivityextends AppCompatActivity {
   Button save, refresh;
   EditTextname;
   ArrayAdapterarrayAdapter;
   LinkedList<String>link_list;
   private ListViewlistView;
   @Override
   protected void onCreate(Bundle readdInstanceState) {
      super.onCreate(readdInstanceState);
      setContentView(R.layout.activity_main);
      link_list = new LinkedList<String>();
      name = findViewById(R.id.name);
      listView = findViewById(R.id.listView);
      findViewById(R.id.refresh).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            arrayAdapter.notifyDataSetChanged();
            listView.invalidateViews();
            listView.refreshDrawableState();
         }
      });
      findViewById(R.id.delete).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if (link_list.size() >0) {
               if (!name.getText().toString().isEmpty()) {
                  link_list.remove(name.getText().toString());
                  arrayAdapter = new ArrayAdapter(MainActivity.this, android.R.layout.simple_list_item_1, link_list);
                  listView.setAdapter(arrayAdapter);
                  Toast.makeText(MainActivity.this, "deleted", Toast.LENGTH_LONG).show();
               }
            } else {
               Toast.makeText(MainActivity.this, "There is no element to delete", Toast.LENGTH_LONG).show();
            }
         }
      });
      findViewById(R.id.save).setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if (!name.getText().toString().isEmpty()) {
               link_list.add(name.getText().toString());
               arrayAdapter = new ArrayAdapter(MainActivity.this, android.R.layout.simple_list_item_1, link_list);
               listView.setAdapter(arrayAdapter);
               Toast.makeText(MainActivity.this, "Inserted", Toast.LENGTH_LONG).show();
            } else {
               name.setError("Enter NAME");
            }
         }
      });
   }
}
