How to Select Single Radio Button in Recycler View in Android ?
First Create A new project and then go to Main Activity ... and i rename it Select plan ...
this is Xml code...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
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"
android:orientation="vertical"
tools:context=".activities.activities.SelectPlan">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="180dp"
android:fontFamily="@font/roboto_bold"
android:text=" Select Your Plan"
android:textColor="@color/black"
android:textSize="24sp">
</TextView>
<androidx.recyclerview.widget.RecyclerView
android:layout_marginTop="10dp"
android:id="@+id/rvSelectPlan"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</androidx.recyclerview.widget.RecyclerView>
<androidx.appcompat.widget.AppCompatButton
android:id="@+id/btnPayNow"
android:layout_marginTop="20dp"
android:layout_width="248dp"
android:layout_height="56dp"
android:textAllCaps="false"
android:layout_marginHorizontal="70dp"
android:background="@drawable/bg_btn"
android:text="Pay Now !"
android:textColor="@color/white"
>
</androidx.appcompat.widget.AppCompatButton>
</LinearLayout>
</ScrollView>
</LinearLayout>
Then Create A custom layout For Select Plan...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<androidx.cardview.widget.CardView
android:id="@+id/cardRadioButton"
android:layout_marginVertical="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="10dp"
app:cardElevation="5dp"
android:layout_marginHorizontal="15dp"
>
<LinearLayout
android:paddingVertical="15dp"
android:id="@+id/LnPlane"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="5dp"
android:weightSum="2"
android:orientation="horizontal"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="0.1"
android:paddingHorizontal="8dp"
>
<RadioButton
android:id="@+id/rdPlan"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_marginLeft="10dp"
android:button="@drawable/radiodraw"
android:buttonTint="@color/black"
android:textColor="@color/black"
android:textSize="14sp"
tools:ignore="TouchTargetSizeCheck" />
</LinearLayout>
<LinearLayout
android:layout_marginHorizontal="5dp"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_weight="1.9"
android:gravity="center_vertical"
>
<TextView
android:id="@+id/txtPlan"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textSize="16sp"
android:fontFamily="@font/roboto_bold"
android:textColor="@color/black"
android:text="Free For 1 Month"
>
</TextView>
<TextView
android:layout_marginTop="5dp"
android:id="@+id/txtDesPlan"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textSize="15sp"
android:textColor="@color/halfBlack"
android:text="Lorem Ipsum is simply dummy text of the."
>
</TextView>
</LinearLayout>
</LinearLayout>
</androidx.cardview.widget.CardView>
</LinearLayout>
Then Create A Model Class .
package com.daizzyinfo.vidhiksahayata.activities.models;
public class SelectPlanModel {
String PlanHeader, PlanDescription;
public SelectPlanModel(String planHeader, String planDescription) {
PlanHeader = planHeader;
PlanDescription = planDescription;
}
public String getPlanHeader() {
return PlanHeader;
}
public void setPlanHeader(String planHeader) {
PlanHeader = planHeader;
}
public String getPlanDescription() {
return PlanDescription;
}
public void setPlanDescription(String planDescription) {
PlanDescription = planDescription;
}
}
Then Create A Adapter Class .
package com.daizzyinfo.vidhiksahayata.activities.adapter;
import android.annotation.SuppressLint;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CompoundButton;
import android.widget.LinearLayout;
import android.widget.RadioButton;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.cardview.widget.CardView;
import androidx.core.content.ContextCompat;
import androidx.core.widget.CompoundButtonCompat;
import androidx.recyclerview.widget.RecyclerView;
import com.daizzyinfo.vidhiksahayata.R;
import com.daizzyinfo.vidhiksahayata.activities.models.SelectPlanModel;
import java.util.ArrayList;
import java.util.List;
public class SelectPlanAdapter extends RecyclerView.Adapter<SelectPlanAdapter.SelectPlanVH> {
Context context;
List<SelectPlanModel> model = new ArrayList<>();
int mSelectedPosition = -1;
public SelectPlanAdapter(Context context, List<SelectPlanModel> model) {
this.context = context;
this.model = model;
}
@NonNull
@Override
public SelectPlanVH onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.custom_select_plan, parent, false);
return new SelectPlanVH(view);
}
@Override
public void onBindViewHolder(@NonNull SelectPlanVH holder, int position) {
holder.txtPlan.setText(model.get(position).getPlanHeader());
holder.txtDesPlan.setText(model.get(position).getPlanDescription());
holder.rdPlan.setChecked(position == mSelectedPosition);
if (position == mSelectedPosition) {
holder.txtPlan.setTextColor(ContextCompat.getColor(context, R.color.white));
holder.txtDesPlan.setTextColor(ContextCompat.getColor(context, R.color.white));
holder.cardRadioButton.setCardBackgroundColor(ContextCompat.getColor(context, R.color.Green));
CompoundButtonCompat.setButtonTintList(holder.rdPlan, ContextCompat.getColorStateList(context, R.color.white));
} else {
holder.txtPlan.setTextColor(ContextCompat.getColor(context, R.color.black));
holder.txtDesPlan.setTextColor(ContextCompat.getColor(context, R.color.black));
holder.cardRadioButton.setCardBackgroundColor(ContextCompat.getColor(context, R.color.white));
CompoundButtonCompat.setButtonTintList(holder.rdPlan, ContextCompat.getColorStateList(context, R.color.black));
}
}
@Override
public int getItemCount() {
return model.size();
}
public class SelectPlanVH extends RecyclerView.ViewHolder implements View.OnClickListener {
CardView cardRadioButton;
TextView txtPlan, txtDesPlan;
RadioButton rdPlan;
public SelectPlanVH(@NonNull View itemView) {
super(itemView);
txtDesPlan = itemView.findViewById(R.id.txtDesPlan);
cardRadioButton = itemView.findViewById(R.id.cardRadioButton);
rdPlan = itemView.findViewById(R.id.rdPlan);
txtPlan = itemView.findViewById(R.id.txtPlan);
itemView.setOnClickListener(this);
rdPlan.setOnClickListener(this);
}
@Override
public void onClick(View v) {
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
if (mSelectedPosition != position) {
int previousSelectedPosition = mSelectedPosition;
mSelectedPosition = position;
notifyItemChanged(previousSelectedPosition);
notifyItemChanged(mSelectedPosition);
}
}
}
}
}
Then Go Main Class Main Activity ( Select Plan).
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.AppCompatButton;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.annotation.SuppressLint;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import com.daizzyinfo.vidhiksahayata.R;
import com.daizzyinfo.vidhiksahayata.activities.adapter.SelectPlanAdapter;
import com.daizzyinfo.vidhiksahayata.activities.models.SelectPlanModel;
import java.util.ArrayList;
import java.util.List;
public class SelectPlan extends AppCompatActivity {
RecyclerView rvSelectPlan;
protected AppCompatButton btnPayNow;
SelectPlanAdapter adapter;
List<SelectPlanModel> model;
@SuppressLint("MissingInflatedId")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_select_plan);
rvSelectPlan=findViewById(R.id.rvSelectPlan);
btnPayNow=findViewById(R.id.btnPayNow);
model = new ArrayList<>();
adapter = new SelectPlanAdapter(this,model);
rvSelectPlan.setAdapter(adapter);
LinearLayoutManager manager = new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false);
rvSelectPlan.setLayoutManager(manager);
model.add(new SelectPlanModel("Free For 1 Month","Lorem Ipsum is simply dummy text of the."));
model.add(new SelectPlanModel("INR 200 for 6 Month","Lorem Ipsum is simply dummy text of the."));
model.add(new SelectPlanModel("INR 300 for 1 Year","Lorem Ipsum is simply dummy text of the."));
}
