//RectangleCalculator app

package com.example.ryan_.rectanglecalculatorapp; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import static java.lang.Math.*; public class MainActivity extends AppCompatActivity { //Defining the widgets  EditText widthInput, heightInput, areaResult, perimeterResult; Button button; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //This is used to set the activity laypout for the app  setContentView(R.layout.activity_main); //Using @+idNumber tags to get and set values  widthInput = (EditText) findViewById(R.id.Number1); heightInput = (EditText) findViewById(R.id.Number2); areaResult = (EditText) findViewById(R.id.Area); perimeterResult = (EditText)findViewById(R.id.Perimeter); button = (Button)findViewById(R.id.button); //Set the listner to the button  button.setOnClickListener(new View.OnClickListener(){ public void onClick(View v){ //Take the user input and calculate the recatnagle features  float width = Float.valueOf(widthInput.getText().toString()); float height = Float.valueOf(heightInput.getText().toString()); final float area = width * height; final float perimeter = 2* width + 2 * height; //Display the results  areaResult.setText(Float.toString(area)); perimeterResult.setText(Float.toString(perimeter)); } }); } }
