title: Can't find the symbol addTextChangedListener
body: <p>I am having issues with addTextChangedListener. I have 2 edittext (edittext1 and edittext2) that when the text (in this case numbers) are added or changed I need it to run a calculation and output it to a textview called resultstext.</p>
  
  <p>I have found many examples and have modified them to do what I need them to do, but when I call the <code>editText1.addTextChangedListener.inputTextwatcher;</code> it tells me it cant find the symbol <code>addTextChangedListener</code>.  Below is the code, how to straighten this out?</p>
  
  <pre><code>package com.example.MyProject;
  
  import android.os.Bundle;
  import android.app.Activity;
  import android.text.Editable;
  import android.view.FocusFinder;
  import android.view.Menu;
  import android.widget.EditText;
  
  public class MainActivity extends Activity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  }
  
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
  
      getMenuInflater().inflate(R.menu.main, menu);
      return true;
  }
  
  private android.widget.EditText editText1;
  private android.widget.EditText editText2;
  private android.widget.TextView resultsText;
  
  
  private void onItemSelected() {
  editText1 = (EditText)findViewById(R.id.textView13);
  editText2 = (EditText)findViewById(R.id.textView15);
  resultsText = (android.widget.TextView)findViewById(R.id.textView16);
  }
  
  
    android.text.TextWatcher inputTextWatcher = new android.text.TextWatcher()
  
  {
      public void afterTextChanged(android.text.Editable s) {
          calculateResult();
      }
      public void beforeTextChanged(CharSequence s, int start, int count, int after){}
      public void onTextChanged(CharSequence s, int start, int before, int count){}
  };
  
  editText1.addTextChangedListener.inputTextWatcher;
  editText2.addTextChangedListener.inputTextWatcher;
  
  private void calculateResult() throws NumberFormatException {
  
      Editable editableValue1 = editText1.getText(),
              editableValue2 = editText2.getText();
  
      double value1 = 0.0,
              value2 = 0.0,
              result;
  
      if (editableValue1 != null)
          value1 = Double.parseDouble(editableValue1.toString());
  
      if (editableValue2 != null)
          value2 = Double.parseDouble(editableValue2.toString());
  
      result = ((0.5 * value1) / 6.1) * value2;
  
  
      resultsText.setText(String.valueOf(result));
  }
  }
