button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                String text1 =editText.getText().toString().trim();
                if (text1.length()!=0) {
                  // Filed is not empty do your code here.
                } else {
                    editText.requestFocus();
                    editText.setError("Enter Text");
                    Toast.makeText(getApplicationContext(),"Enter Text",Toast.LENGTH_SHORT).show();
                }
           }
        });

Another way is to addTextChangedListener to your EdiText

Like this:

yourEditText.addTextChangedListener(new TextWatcher() {
      @Override
      public void afterTextChanged(Editable arg0) {
         enableSubmitIfReady();
      }

      @Override
      public void beforeTextChanged(CharSequence s, int start, int count, int after) {
      }

      @Override
      public void onTextChanged(CharSequence s, int start, int before, int count) {
      }
    });

In that method, you should do like this:

 public void enableSubmitIfReady() {

    boolean isReady =yourEditText.getText().toString().length()>1;

    if (isReady) {
      yourbutton.setEnabled(true);
   } else {
      yourbutton.setEnabled(false);
    }
  }

Hope it helps.

Hey Thanks.... i knew the Onclick Listener. It works when the user clicks a button. But i disabled the button initially. — magdoon basha, Dec 30 '14 at 05:49

Use TextWatcher in android for both text fields.

Use following code

TextWatcher textWatcher = new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {

    }

    @Override
    public void afterTextChanged(Editable s) {
        validateFields();
    }
};

validateFields() method

protected void validateFields() {

    if(edt1.getText().length()>0 && edt2.getText().length()>0){
        btnLogin.setEnabled(true);
    }else{
        btnLogin.setEnabled(false);
    }
}

Inside validateFields() method, you can check length of input fields. If length are more than 0, you can enable Login button.
