The key is to check for the success of insert operation

   EditText texto = (EditText) findViewById(R.id.etAdd);

            Button add = (Button) findViewById(R.id.bAdd);
            add.setOnClickListener(new OnClickListener() {

                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    try{
                        //Abre ou Cria uma database com nome de: "dbtest.db"
                        db = openOrCreateDatabase("dbtest.db", Context.MODE_PRIVATE, null);
                        String resultado = texto.getText().toString();

                        try{
                            long result = db.insert("usuarioorigem", resultado, null);
                            if(result == -1){
                               ShowMessage("Error in Insert"); //sorry for english here, may be u can use inserido
                            }
                            else{
                               ShowMessage("Mensagens Inserido" +resultado+ "com sucesso!");
                            }
                        }finally{

                        }
                }finally{

                }
                }
            });


    private void ShowMessage(String msg){
        Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
    }

Your ShowMessage function could look like this:

private void ShowMessage(String msg){
    Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
}
