For Activity java class first we need to get the Button id using findIdbyView method and then we override the onclicklistener method onClick  with which a Toast with the String inside it and length defined will be shown on the mobile screen .

package javainhouse.com.toastexample; import android.content.Context; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.Gravity; import android.view.LayoutInflater; import android.view.View; import android.widget.Button; import android.widget.Toast; public class ToastActivity extends AppCompatActivity {     private Button toastExample;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_toast);         toastExample = (Button) findViewById(R.id.buttonToast);         // Button click listner         toastExample.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 Context context = getApplicationContext();                // Toast toast = new Toast(context);                 Toast.makeText(getApplicationContext(),                         "Hello Toast", Toast.LENGTH_LONG)                         .show();             }         });     } }
