title: Android EditText dynamic height programmatically
body: <p>i got a little problem with my EditText. I want it to automatically increase its height. I found other people asking for it: <a href="https://stackoverflow.com/questions/12537819/how-to-make-edittext-box-height-expand">like this one</a></p>
  
  <p>My problem is that im not using a XML-File. I just use my Java-Code:</p>
  
  <pre><code>public class CommentatorView extends LinearLayout {
  
  //Variablen um den Taschenrechner anzupassen
  final static float KLEIN = 0.75f;
  final static float MITTEL = 1.0f;
  final static float GROS = 1.5f;
  final static float GROS_1 = 2.0f;
  final static float GROS_2 = 3.0f;
  final static float GROS_3 = 4.0f;
  
  
  CommentatorListener clickListener;
  Commentator goTo;
  EditText commentField;
  public CommentatorView(Commentator goTo) {
      super(goTo.getContext());
  
      this.setOrientation(LinearLayout.VERTICAL);
      this.goTo = goTo;
      clickListener = new CommentatorListener(this, goTo);
  
      commentField = new EditText(this.getContext());
      commentField.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
      commentField.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);
  
      commentField.setMinHeight(120);
      this.addComponent();
  }
  
  private void addComponent() {
  
      this.addView(this.commentField);
  
      LinearLayout linearLayout = new LinearLayout(this.getContext());
  
      LayoutParams buttonParams = new LayoutParams(0, LayoutParams.WRAP_CONTENT);
      buttonParams.weight = 1;
      buttonParams.setMargins(1, 0, 1, 0);
  
      Button btnSave = new Button(this.getContext());
      btnSave.setOnClickListener(this.clickListener);
      btnSave.setTypeface(null, Typeface.BOLD);
      btnSave.setTextSize(18);
      btnSave.setText("Speichern");
      btnSave.setTag("save");
      linearLayout.addView(btnSave, buttonParams);
  
      Button btnCancel = new Button(this.getContext());
      btnCancel.setOnClickListener(this.clickListener);
      btnCancel.setTypeface(null, Typeface.BOLD);
      btnCancel.setText("Abbrechen");
      btnCancel.setTag("no");
      btnCancel.setTextSize(18);
  
      linearLayout.addView(btnCancel, buttonParams);
  
      this.addView(linearLayout);
  }
  
  public int getWantedNumber() {
      int i = Integer.parseInt(commentField.getText().toString());
      return i;
  }
  
  public boolean isNumber() {
      try {
          int d = Integer.parseInt(commentField.getText().toString());
          Log.i("WTG", "" + d);
      } catch (NumberFormatException nfe) {
          Log.e("WTG", "Cast failed");
          return false;
      }
      return true;
  }}
  </code></pre>
  
  <p>Is there any way to get in automatically increasing height with just my java code?</p>
  
  <p>Thanks in advance!</p>
