Select only returns last Sqlite database record

Question

I don’t have much programming experience and I’m having trouble with a BD query. It’s only returning the last data entered. I need to list all records entered in this table.

@Override
    public void onCreate(SQLiteDatabase db) {
        String table_altura = "CREATE TABLE "+TABLE1+"(altura_id INTEGER PRIMARY KEY AUTOINCREMENT,altura_data TEXT," +
                "altura TEXT)";
        String table_perimetro = "CREATE TABLE "+TABLE2+"(perimetro_id INTEGER PRIMARY KEY AUTOINCREMENT,perimetro_data TEXT," +
                "perimetro TEXT)";
        String table_peso = "CREATE TABLE "+TABLE3+"(peso_id INTEGER PRIMARY KEY AUTOINCREMENT,peso_data TEXT,peso TEXT)";
        String table_vacina = "CREATE TABLE "+TABLE4+"(vacina_id INTEGER PRIMARY KEY AUTOINCREMENT,vacina_data TEXT," +
                "vacina TEXT)";
        String table_doc = "CREATE TABLE "+TABLE5+"(doc_id INTEGER PRIMARY KEY AUTOINCREMENT,num_cpf TEXT,num_sus TEXT," +
                "num_convenio TEXT,num_rg TEXT)";
        String table_dados_bebe = "CREATE TABLE "+TABLE6+"(dados_bebe_id INTEGER PRIMARY KEY AUTOINCREMENT,nome_bebe TEXT,sobrenome_bebe TEXT," +
                "data_nasc_bebe TEXT,tipo_sangue TEXT,naturalidade TEXT,maternidade TEXT,hora_nasc TEXT,tipo_parto TEXT,genero TEXT, foto_bebe TEXT)";
        db.execSQL(table_altura);
        db.execSQL(table_perimetro);
        db.execSQL(table_peso);
        db.execSQL(table_vacina);
        db.execSQL(table_doc);
        db.execSQL(table_dados_bebe);
    }
