    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/txtTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:layout_marginTop="80dp"
        android:text="Candidroot solutions"
        android:textAlignment="center"
        android:textSize="18sp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.842"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <EditText
        android:id="@+id/editText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txtTitle"
        android:layout_marginStart="30dp"
        android:layout_marginTop="104dp"
        android:layout_marginEnd="30dp"
        android:visibility="gone"
        android:hint="Typing...."
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/txtTitle" />

    <Button
        android:id="@+id/btnsubmit"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="76dp"
        android:text="Click to show toast"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.498"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/editText" />

    <Button

        android:layout_marginTop="24dp"
        android:text="Click to show Alert Dialog"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/btnsubmit" />
 </androidx.constraintlayout.widget.ConstraintLayout>

 import android.os.Bundle;
 import android.widget.Button;
 import androidx.appcompat.app.AppCompatActivity;

 public class MainActivity extends AppCompatActivity {
    
    @Override

        Button buttonsend = findViewById(R.id.btnsubmit);
        Button btnsubmitAlertDialog = findViewById(R.id.btnsubmitAlertDialog);
        buttonsend.setOnClickListener(v -> {
            StaticMethod.displayToast(MainActivity.this, getString(R.string.app_name));
        });
        btnsubmitAlertDialog.setOnClickListener(v -> {
            StaticMethod.displayAlertDialog(MainActivity.this, getString(R.string.app_name), "welcome ");
