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);
try {
db.insert("usuarioorigem", resultado, null);
ShowMessage("Mensagens","Inserido" +resultado+ "com sucesso!");
} finally {

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();
}
