Create a Wheel View Dialog in Android (Scroll view in Dialog Box)

In this post, we will show you how to create a Wheel View (Scroll View in Dialog Box) in Android

By creating a Wheel View Dialog in Android, you can add some values by clicking on a button and select from those values and then set it on somewhere else.

To create a Wheel View, we add a Wheel View library in our app-level Gradle File.

app-level Gradle file

 implementation 'com.wx.wheelview:wheelview:1.3.3'  

Then add a TextView in .xml file

 <?xml version="1.0" encoding="utf-8"?>  
 <android.support.constraint.ConstraintLayout 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"  
   tools:context=".SampleActivity">  
   <TextView  
     android:layout_width="wrap_content"  
     android:layout_height="wrap_content"  
     android:text="Wheel View Sample Dialog"  
     android:gravity="center_horizontal"  
     android:textSize="36sp"  
     android:id="@+id/wheel_view_tv"/>  
 </android.support.constraint.ConstraintLayout>  

Then create an ArrayList and a Wheel View Dialog method in Java file and use that dialog method in on click listener of TextView.

 package studio.harpreet.sampleproject;  
 import android.graphics.Color;  
 import android.support.v7.app.AppCompatActivity;  
 import android.os.Bundle;  
 import android.view.View;  
 import android.widget.TextView;  
 import android.widget.Toast;  
 import com.wx.wheelview.widget.WheelView;  
 import com.wx.wheelview.widget.WheelViewDialog;  
 import java.util.ArrayList;  
 public class SampleActivity extends AppCompatActivity {  
   TextView tv;  
   @Override  
   protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_sample2);  
     tv = findViewById(R.id.wheel_view_tv);  
     tv.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View view) {  
         show_wheelView();  
       }  
     });  
   }  
   private void show_wheelView()  
   {  
     WheelViewDialog dialog = new WheelViewDialog(this);  
     dialog.setTitle("Dialog Title")  
         .setItems(wheel_count())  
         .setDialogStyle(Color.parseColor("#6699ff"))  
         .setCount(3)  
         .setLoop(true)  
         .setButtonText("Ok")  
         .setOnDialogItemClickListener(new WheelViewDialog.OnDialogItemClickListener() {  
           @Override  
           public void onItemClick(int position, String s) {  
             Toast.makeText(SampleActivity.this, "You Click on "+s+" Value", Toast.LENGTH_SHORT).show();  
           }  
         })  
         .show();  
   }  
   private ArrayList<String> wheel_count()  
   {  
     ArrayList<String> arraylist = new ArrayList<>();  
     arraylist.add("5");  
     arraylist.add("10");  
     arraylist.add("15");  
     arraylist.add("20");  
     arraylist.add("25");  
     arraylist.add("30");  
     arraylist.add("35");  
     arraylist.add("40");  
     arraylist.add("45");  
     arraylist.add("50");  
     return arraylist;  
   }  
 }  

Now, when we run our app and click on text view then our Wheel View dialog is shown and Working perfectly.
