  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

  @Override
  public void onClick(View v) {
  // TODO Auto-generated method stub
  reciver.setText("");
  }
    });
    cc.setOnClickListener(new OnClickListener(){
  @Override
  public void onClick(View v) {
  // TODO Auto-generated method stub
  cc.setText("");
  }
    });
    subject.setOnClickListener(new OnClickListener(){
  @Override
  public void onClick(View v) {
  // TODO Auto-generated method stub
  subject.setText("");
  }
    });
    body.setOnClickListener(new OnClickListener(){
  @Override
  public void onClick(View v) {
  // TODO Auto-generated method stub
  body.setText("");
  }
    });
    reciver.setOnKeyListener(new OnKeyListener(){
  @Override
  public boolean onKey(View v, int keyCode, KeyEvent event) {
  // TODO Auto-generated method stub
  if(isEmail(reciver.getText().toString())){
   b.setEnabled(true);
  }
  else{
   b.setEnabled(false);
  }
  return false;
  }
    });
    b.setOnClickListener(new OnClickListener(){
  @Override
  public void onClick(View v) {
  // TODO Auto-generated method stub
  strReciver=new String[]{reciver.getText().toString()};
  strCc=new String[]{cc.getText().toString()};
  strSubject=subject.getText().toString();
  strBody=body.getText().toString();
  Intent i=new Intent(android.content.Intent.ACTION_SEND);
  i.putExtra(android.content.Intent.EXTRA_EMAIL, strReciver);
  i.putExtra(android.content.Intent.EXTRA_CC, strCc);
  i.putExtra(android.content.Intent.EXTRA_SUBJECT, strSubject);
  i.putExtra(android.content.Intent.EXTRA_TEXT, strBody);
  startActivity(Intent.createChooser(i, getResources().getString(R.string.str_message)));
  }
    });
  }
  public static boolean isEmail(String s){
   String expression="^[a-zA-Z][w.-]*[a-zA-Z0-9]@[a-zA-Z0-9][w.-]*[a-zA-Z0-9].[a-zA-Z][a-zA-Z.]*[a-zA-Z]$";
   Pattern p=Pattern.compile(expression);
   Matcher m=p.matcher(s);
   return m.matches();
  }
